Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your
particular application.
WARNING
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.
WARNING
The equipment used contains ESD sensitive ports. 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.

1. INTRODUCTION
The XBT32-3FTP is a programmable benchtop power supply that provides
variable DC low voltage power to devices and assemblies in a laboratory setting.
This section provides an overview of the XBT32-3FTP DC Power Supply and
lists its features, functions and specifications.
1.1 Overview
The XBT32-3FTP is a programmable DC power supply with three (3) outputs:
Channel 1 and Channel 2 are linear power supplies and Channel 3 is a switching
mode power supply. XBT32-3FTP comes with 16 bits resolution. The maximum
total output power is 222 watts with both Channel 1 and Channel 2 providing 96
watts each (0 ~ 32V/3A) and Channel 3 providing a maximum of 30 watts (0 ~
15V/5A). This means that when the Channel 3 output voltage is set to 6 volts or
less, the output current can be up to 5A. If the Channel 3 output voltage is set
above 6 volts then the maximum output current depends on the voltage setting
with the output power of 30 watts. This is a unique feature that differs from
traditional power supplies.
1.2 Features and Functions
In addition to the triple independent output, other important features and
functions include:
•parallel mode for an output current up to 6A
•series mode for an output voltage up to 64V
•precision voltage and current measurement
•dual tracking
•digital rotary and push button controls
•LCD display

2.3 Power-Line Voltage
The power supply uses AC power 115V/230V 50Hz/60Hz. Before plugging in the
power cord, make sure the POWER switch (see Section 3.1) is in the OFF
position and the voltage input selection switch on the bottom of the unit is the
same as the required voltage.
Caution
Exceeding the maximum rated AC input voltage could result
in damage to the unit.
2.4 Fuse
There is one fuse installed in the rear panel. If and when it becomes necessary to
replace the fuse, first turn off the power and disconnect the AC power cord and
all other connections to the power supply. Open the fuse cover, located on the
rear panel below the AC socket, using a flat-head screwdriver or by holder from
under the AC socket.
Mark Range Fuse Max Power

230 207V~253V T2.5A /250V 500VA
50/60 Hz
Caution
For continuous protection against fire hazard, replace fuse
only with the same type and rating specified.
2.5 Connections
Of the interface connections available, RS-232 and USB are standard interfaces,
and the GPIB and Ethernet interfaces are options.
2.6 Warming Up
