Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNIN
G
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
WARNIN
G
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance
equipment must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must
ensure that the output power lines are labeled properly as to the safety hazards and that any
inadvertent contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury,
loss or damage that results from improper use of the equipment and accessories.

1Features and
Specifications
Chapter 1 describes the XFR 2800 Watt Series
Programmable DC Power Supply and lists the features.

Features and Specifications
1-2 TM-F2OP-C1XN-01
Description
This series of power supplies provides low noise, precisely regulated,
variable DC output at 2800 watts of output power. Over voltage
protection (OVP) and thermal shutdown are standard. Front panel
controls and indicators are extensive. Select from several remote control
choices: standard analog programming, optional isolated programming or
readback, and optional GPIB programming or RS-232 control. Remote
monitoring of output voltage and current is a standard feature. Use this
power supply either on your bench or in a standard 19 in. (483 mm) rack:
the unit occupies only 3.5 in. (2 U) of vertical rack space. Designed for
continuous use in standalone or systems applications, this power supply is
typically used to power DC equipment, control magnets, or burn in
components. See Table 1-1 for the list of available models.

Features and Options
TM-F2OP-C1XN-01 1-3
Features and Options
• Simultaneous digital display of both voltage and current.
• Ten-turn front panel voltage and current controls for high resolution
setting of the output voltage and current from zero to the rated output.
• Automatic mode crossover into current or voltage mode.
• Front panel push-button control of output standby mode and preview
of voltage, current, or over voltage protection setpoints. Front panel
light emitting diode (LED) indicators for voltage and current mode
operation, OVP, remote programming mode, and shutdown. Front
panel control of OVP.
• Multiple units can be connected in parallel or in series to provide
increased current or voltage.
• Over temperature protection (OTP) shutdown; latches or
automatically resets.
• Remote analog voltage and current limit programming with selectable
programming ranges.
• External monitor signals for output voltage and current.
• Isolated analog remote programming control of the output voltage or
current and isolated readback of output voltage and current with the
optional ISOL Interface.
• Optional internal GPIB or RS-232 control for remote digital
programming and readback from a computer.
• Rack mount brackets at the front panel are standard.
