PF1 SSR Power Controller Description
Rev 3 Ametek HDR Power Systems 3
CHAPTER 1 - Description
1.1 General Description
The PF1 is a Single-phase, phase-fired power controller, and can operate with a wide variety of input
signals and line voltages up to 575 Vac and currents ranging from 15 through 70 amperes. The PF1’s
output voltage is proportional to its input signal. The PF1 SSR Series utilizes an isolated base Solid-
State-Relay (SSR) Module which contains two SCRs connected back to back. The firing circuit is
based on a common phase firing integrated circuit which includes soft-start for loads which have a
large resistance change due to temperature or start-up. Terminals are provided to ease installation.
1.2 Application
The PF1 provides infinitely variable firing angles for precise control of single-phase power to resistive
or loads with large resistance change (cold to hot). The PF1 may also be used on straight resistive
loads as well, but the lower power factor and higher harmonics may present a problem to other
equipment mounted nearby. A zero fired model may be a better choice for non-transformer coupled
loads.
1.3 Specification
Specifications for the PF1 SSR power controller are given in Tables 1.1 and 1.2.
Table 1.1 PF1 Model Number Breakdown
PF1 – 480 – 25 – CL – FK – 01
NOTE: * Required for operation.
1.4 Option NO/NC (Thermostat)
Heatsink Thermostats (Option NO or NC) provide a dry contact either Normally Open (NO) or Normally
Closed (NC).
1.5 Option FK (Fuse Kit)
The Fuse Kit (Option FK) consists of a Semi-Conductor Fuse and a fuse block. It is the user's
responsibility to mount this fuse kit and connect in series with the Line of the Power Controller.
1.6 Option TX (24 Vac Transformer)
The PF1 requires 24 Vac @ 3VA control power. Appropriate sized transformer (Option TX) is available
with 120, 240, 400, 480 or 600 V ac primaries.

NOTE: The PF1 should be tested or operated with an adequate load since an open output will have line
voltage at the load connections.
1.7 Option OC (Overcurrent Trip)
The Overcurrent Trip Option (OC) provides circuit protection from output current overloads by serving
as a fast-gate shutdown (functions similar to an electronic fuse). Current transformers on the SCR
Power Control’s input lines allow Option OC to monitor instantaneous peak current. When the peak
current level exceeds the preset trip level, SCRs are gated off, and the load current is shut down within
1/2 cycle. Trip point is adjustable from 30% to 200% of the current transformer rating. The RESET
pushbutton on the OC Trip PCB must be manually reset to resume operation.
The Overcurrent Trip Option includes a Form C relay output and provisions for a remote overcurrent
reset push button. Reference Appendix G.
1.8 Option CL (Current Limit)
The Current Limit Option (CL) prevents the output current of an SCR Power Control from exceeding a
preset maximum current level, as determined by the current limit control setting (30% to 125%). The
current limit adjustment is located on the current limit PCB, reference Appendix F.

PF1 SSR Power Controller Installation
Rev 3 Ametek HDR Power Systems 5
CHAPTER 2 - Installation
2.1 Mounting the PF1
Determine space and mounting hole requirements by referring to the outline drawing (in the Appendix)
that applies to your model’s current rating. Mount the unit so the line and load connections are at the
top and ensure that upward airflow over the heat sink fins is unrestricted.
2.2 Load Wiring
Connect the load to the proper terminals (refer to the input/output connections schematic in Appendix
A) using appropriately sized and insulated conductors. All input/output conductors should be stranded
copper wire only; minimum temperature rating is 75ºC.
2.3 Line Wiring
Connect input lines from the fused disconnect or circuit breaker to the Line terminal (refer to the
input/output connections diagram) using appropriately sized and insulated conductors. (NOTE: Input
power should be routed through a fused disconnect or circuit breaker with a fuse or trip rating of 100%
to 125% of the current rating stamped on the nameplate of the PF1 series unit.)
Torque Line and Load connection to 45 in-lbs.
Mount and connect the Control transformer (Option TX) per the schematic in Appendix A. Select the
appropriate Transformer voltage tap as shown in Table 2.1 and solder wires to the primary terminals.
An insulator is also provided to install between the transformer and the mounting plate.

WARNING - ELECTRIC SHOCK CAN KILL
HAZARDOUS VOLTAGES exist at the (LINE and LOAD) terminals when the
input voltage is connected. This condition exists even when the Controller is
set to deliver zero output. Always remove power and properly lock out power to
the unit before attempting any service, including the load.
WARNING
Branch circuit overcurrent protection required is to be provided in accordance
with the national and local codes of the inspecting authority.

2.4 Wiring Input Fuse
An Option (FK) Fuse Kit is available with high speed fuses (I²T) to protect the Solidstate Relays (SSR)
from Load shorts. The fuses are NOT meant for over current protection, separate branch circuit
protection is required. Mount the fuse blocks, reference Appendix E for mounting details.
2.5 Optional Current Transformer
Install the Current transformer for option OC or CL near the Line connection, reference Appendix F &
G for mounting. Run L1 through current transformer the amount of turns shown in Table 2.2. Connect
the cable provided from the CT PCB to the Firing Circuit PCB and adjust pot to desired current or trip
level per 3.3.

2.6 Command Signal Input
HDR’s PF1 SSR Power Controllers have the capability of having a current, voltage or potentiometer
Command Signal input. For current command (4-20 mA) a 500 ohm 1/4 W resistor is connected
across terminals 1 and 2, for voltage command and remote potentiometer the 500 ohm resistor is
removed. A potentiometer may be located on a remote panel near other controls related to the
process being powered by the PF1. The potentiometer should be rated 5 kΩ, 1/2 Watt minimum.
Reference the schematic in Appendix A.
The Command Signal is NOT isolated from the Line. An isolated device such as an isolated PLC
output module to drive the command signal is required or damage can occur to the Power Controller.
2.7 Heatsink Thermostat Contacts
Normally-open (N.O.) or normally-closed (N.C.) thermostat is mounted to the heat sink when this
option is purchased. This thermostat, which close or open on high heat sink temperature (200 ºF),
may be used to initiate an alarm, shunt trip, or other device for SCR protection.

PF1 SSR Power Controller Operation
Rev 3 Ametek HDR Power Systems 7
CHAPTER 3 - Operation
3.1 General
The PF1 controls power by the switching action of two SCRs connected in a back to back
configuration. The gating of these SCRs is synchronized with the line frequency (either 50 or 60 Hz)
by the Phase Control Integrated Circuit and the 24 Vac control voltage. This IC provides timing pulses
along with a soft-start feature. The output may be adjusted by the on-board potentiometers or by a
voltage or current signal from a process controller. Zero and Span controls allow the user to calibrate
the SSR unit's output to the process command signal.
3.2 Command Indicator
The Command Indicator is a green Light Emitting Diode (LED) located on the Firing board. The
brilliance of this LED will change with a Command Signal. The flash rate increases with an increased
Command Signal and decreases with a decreased Command Signal
3.3 Command Input Control
Connect the control signal per the schematic in Appendix A. The PF1 Zero and Span is calibrated at
the Factory for the specified input type and normally does NOT need adjustment. However, should a
setup be required use the following methods. (Note: Adjustments requires a jeweler’s screw driver for
multi-turn bias & gain adjustments.)
The output voltage linearity for any given command is affected by the setting of the Zero and Span
adjustments.
a. Set the ZERO and SPAN controls fully CCW (counterclockwise). If Option OC or CL are installed
set the Trip Level potentiometer full CW.
b. Connect a voltmeter across terminals LINE and LOAD of the PF1. Set the voltmeter range to
measure full input voltage.
c. Close the fused disconnect or circuit breaker to apply power to the PF1. Turn the Process
controller on and set to demand zero power output or remote potentiometer fully CCW.
d. Adjust the ZERO control CW until the output just turns on, then turn the ZERO control CCW just to
the point where the output voltage reading is zero.
e. Set the Process controller to demand 100% output or the remote potentiometer fully CW.
Observing the voltmeter, adjust SPAN CW just to the point where the reading is below the
maximum output voltage. Then adjust SPAN CW just to the point where the meter reading is at
maximum.
f. Repeat steps 3.3d through 3.3e as necessary, to ensure proper control adjustments have been
made.
g. If Option OC or CL is installed, set the power controller at full output, adjust the Trip Level
potentiometer CCW until the output current is limited to the desired level. Then adjust the Trip
Level potentiometer slightly CW. If Option OC, Momentarily press the RESET pushbutton on the
Current Limit option PCB.
h. Turn off the line power to the PF1 and disconnect the test equipment. The PF1 is now ready for
operation.

PF1 SSR Power Controller Troubleshooting
Rev 3 Ametek HDR Power Systems 9
CHAPTER 4 – Troubleshooting
4.1 Customer-Service Program
Although service is seldom necessary, because of the inherent long-term reliability of solid-state
components and conservative design, Ametek HDR Power Systems emphasizes customer satisfaction
by maintaining a rapid-response and cooperative customer-service. If operational difficulties occur,
Ametek HDR Power Systems will provide replacement parts or units quickly, courteously and
efficiently. If servicing problems arise that are not within the scope of the following troubleshooting
guide, service is readily available, as detailed in Chapter 5.
4.2 Troubleshooting Typical Symptoms
The PF1 is considered to be operating properly when its output voltage can be satisfactorily varied
from 0% to 97% of the available input voltage by a control signal. Improper operation of the unit is
usually indicated by one of the following symptoms:
a. No output.
b. Full output at all times, with no change resulting from a control signal change.
c. Output variable from some intermediate value to maximum, but cannot be brought to zero.
d. Output variable from zero to some intermediate value, but cannot be brought to maximum.
The symptoms listed may be caused by one or more of the following: an environmental problem,
faulty input-power or load connections, and the PF1 itself. These possible causes should be
investigated as described in Chapters 4.4 through 4.6.
4.3 Static Precautions when Servicing
Servicing should be performed by qualified personnel only, following procedures described herein.
If troubleshooting indicates a need to replace a component on a printed circuit board or possibly the
entire board, measures to prevent electrostatic discharge (ESD) damage must be taken.
a. ALWAYS wear a wrist strap connected to ground through a 1-megohm resistor when working on
printed circuit boards.
b. Use soldering iron with a grounded tip.
c. Use a non-static solder sucker (metallic) or solder removal braid.
WARNING - ELECTRIC SHOCK CAN KILL
HAZARDOUS VOLTAGES exist at the exposed (LINE and LOAD) terminals
unless the line-source fused disconnect or circuit breaker is open or off.
This is true even when the SCR’s are turned off. Always remove power and
properly lock out power to the unit before attempting any service is
performed.
ATTENTION
Printed circuit boards contain sensitive components that can be damaged
by electrostatic discharge (ESD). Observe precautions for handling
electrostatic sensitive devices.

Troubleshooting PF1 SSR Power Controller
10 Ametek HDR Power Systems Rev 3
d. Transport static sensitive components in static shielding bags or rails. A new printed circuit board
should be treated as a static sensitive device. A part completely installed on a board does not
make the part static-safe.
e. If possible, perform printed circuit board maintenance at a work station that has a conductive
covering which is grounded through a 1-megohm resistor. If a conductive table top is unavailable,
a clean steel or aluminum table top is an excellent substitute.
f. Keep plastic, vinyl, Styrofoam or other non-conductive materials away from printed circuit boards.
They are good static generators that do not give up their charge easily.
g. Return goods to Ametek HDR Power Systems in static-safe packaging. This will limit further
component damage from ESD.
h. CAUTION. Do not touch any printed circuit board unless you are wearing a ground wrist strap, as
circuit damage may occur. Grounding kits are also available commercially and can be purchased
through most electronic wholesalers.
4.4 Environmental Problems
Check to see that none of the following environmental problems exist.
Inadequate Cooling. Allow at least 1 inch of air space (in any direction) between the heat sinks and
any item or structure near the PF1 power modules. Heat sink fins should be free of dust or dirt for
proper heat transfer, and free of obstructions which could prevent proper airflow.
Contamination. The unit should be periodically cleaned of all dust and dirt. However, certain kinds of
dust or particles are particularly conductive. A small accumulation of conductive material can cause
component failures from arc-over or complete shorts.
High Ambient Temperature. Lack of a proper ambient-temperature check before installation, or an
increase in ambient temperature, can result in numerous problems. Check the ambient temperature
under existing conditions. If it is 122 ºF (50 ºC) or lower, ambient temperature should not be a
problem. If it is above 122 ºF (50 ºC), steps should be taken to provide more cooling, or the PF1
should be moved to a cooler location, or call the Ametek HDR Power Systems service department.
Excessive Vibration. A significant degree of pitched or unpitched vibration can cause numerous
problems. If vibration is isolated as a probable cause of improper operation, standard vibration-
isolation mounting techniques should be employed.
4.5 Input Power and Load Connections
Turn off the power to the PF1 and check all power connections, input and output, to make sure they
are mechanically secure and free of corrosion. Make the same checks at the power source and load.
Visually check insulation on input and load wiring for evidence of damage or overheating.
