This instrument is intended for indoor use in an installation category I, pollution degree 2
environments. It is designed to operate at a maximum relative humidity of 80% and at
altitudes of up to 2000 meters / 6560 feet. Refer to the specifications tables for the ac mains
voltage requirements and ambient operating temperature range.
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage and the correct fuse is
installed.
GROUND THE INSTRUMENT
This product is a Safety Class 1 instrument (provided with a protective earth terminal). To
minimize shock hazard, the instrument chassis and cabinet must be connected to an
electrical ground. The instrument must be connected to the AC power source mains through
a properly rated power cord, with the ground wire firmly connected to an electrical ground
(safety ground) at the power outlet. Any interruption of the protective (grounding)
conductor or disconnection of the protective earth terminal will cause a potential shock
hazard that could result in personal injury.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal blow, time
delay, etc.) should be used. Do not use repaired Fuses or short circuit the fuse holder. To do
so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.

KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and
internal adjustments must be made by qualified service personnel. Do not replace
components with power cable connected. Under certain conditions, dangerous voltages
may exist even with the power cable removed. To avoid injuries, always disconnect power,
discharge circuits and remove external voltage sources before touching components.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering
first aid and resuscitation, is present.
DO NOT EXCEED INPUT RATINGS.
This instrument may be equipped with a line filter to reduce electromagnetic interference
and must be connected to a properly grounded receptacle to minimize electric shock
hazard. Operation at line voltages or frequencies in excess of those stated on the data plate
may cause leakage currents in excess of 5.0 mA peak.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or
perform any unauthorized modification to the instrument. Return the instrument to an
Adaptive Power Systems Sales and Service Office for service and repair to ensure that safety
features are maintained.
Instruments that appear damaged or defective should be made inoperative and secured
against unintended operation until they can be repaired by qualified service personnel.

3.3 Operating Modes
The CFS300 Series offers three modes of operation that are user selectable through the
System soft key.
Mode
Description
Output Mode
PROGRAM
Go/No Go Limit testing for AC powered product. This
mode uses one of 50 Memories that store up to nine
test steps each. Each test step will apply user set
output frequency, voltage and current limit to the unit
under test. Duration of each test step is set by the user
for each step. During each step, measurements are
taken and compared against user set pass/fail limits.
Any measurement that falls outside one or more limits
results in a FAIL.
AC
MANUAL
MANUAL mode provides interactive operation in AC
mode. In this mode, frequency, voltage and current
limit can be set. After applying power to the unit under
test, all measurements are shown in the Measurement
display. Two measurements – one of which is always
VOLTAGE - are shown in large font so they can be read
from a distance. The other measurements are shown
in smaller font in the top portion of the LCD display.
The ‘Meter” soft key allows the user to toggle the
second large readout between the other available
measurements. While in measurement display mode,
the shuttle can be used to adjust either voltage or
frequency.
AC
DC
DC Mode is the same as MANUAL mode but, provides
DC output mode instead. Measurements in DC mode
are limited to Voltage DC (Volts), Current DC (Amps)
and True Power (Watt)
DC

3.4 Voltage Programming
Voltage settings are similar between PROGRAM, MANAUL and DC modes. Two voltage
ranges are available, a LOW (AUTO) range and a HIGH range. Low range is always half the
maximum available voltage on the HIGH range. Maximum current in the LOW (AUTO) range
is two times that of the HIGH Range. The HIGH range allows the maximum voltage to be
programmed.
Range values are different for AC and DC modes as follows:
Mode
LOW RANGE (AUTO)
HIGH RANGE
PROGRAM or MANUAL
5 Vac – 150 Vac RMS (1 Phs)
8.7 Vac – 260Vac (3 Phs)
5 Vac – 300 Vac RMS (1 Phs)
8.7 Vac – 520Vac (3 Phs)
DC
5 Vdc – 210 Vdc
5 Vdc – 420 Vdc
Table 4-1: Available Voltage Ranges by Output Mode
See specifications in Sections 5.1and 5.2 for each mode.
3.4.1 Minimum Voltage
Programming resolution is 0.1V in all modes and on all voltage ranges. Notethat values
below 5Vac or 5Vdc cannot be programmed. At voltage lower than 5V, load regulation and
voltage distortion (AC mode) are difficult to maintain.
To apply zero volts to the output, turn the output OFF using the TEST button.
3.4.2 Voltage Range AUTO mode
The CFS will auto range when set to the AUTO (LOW) VOLTAGE range so values over 150Vac
or 200Vdc will cause the power source to switch to HIGH range automatically. When set to
HIGH Voltage Range, the power source will remain on the high voltage range at all times,
regardless of programmed voltage.
Note: If set to AUTO Range, the power source will switch from LOW range to HIGH range
when a set value of 150V in AC mode or 200V in DC mode or higher is programmed,
either in MANUAL mode or as part of a program memory step in PROGRAM mode.

3.5 Current Protection Modes
Current protection is an important feature on programmable power sources as it allows
protection of the unit under test against damage caused by over current conditions. The
default setting for current limit is the maximum supported value for the voltage range
selected. However, it should be set to a value appropriate for protecting the unit under
test, before applying power. Current limit set values are in Aac RMS for AC mode and Adc
for DC mode.
Current protection mode is available using one of two modes of operation:
Current Fold-Back: In this mode, load current is limited to the set current limit value by
reducing the output voltage. Thus, while in fold back mode, the
output voltage will be less than the programmed (set) voltage. As
the load impedance increases and thus the load current decreases,
the voltage will go up until the load current is at or below the
programmed current limit value and the voltage is at the set value.
Current Fault Mode: In this mode, the CFS300 will fault and open the output relay when
the load current exceeds the set current limit value for some period
of time. This time period depends on the amount of load current. At
current levels slightly above the set value, this time may be fairly
long. At load currents significantly higher than the set current level
– i.e. a short circuit condition - , this period will be very short.
The protection mode selection is available in the System setup menu under “OC Fold”.
Available settings are:
•OC Fold = ON Enables voltage fold back mode
•OC Fold = OFF Disables voltage fold back mode

3.6 Voltage & Current Output Profiles
The CFS series provides higher load current at lower voltage as long as the total output
power is within its power band. This results in a constant power voltage/current profile as
shown in the following charts for each model by output mode (AC or DC), and voltage range
(high (300Vac/420Vdc) or low (150Vac/210Vdc)).
