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

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.

The equipment used contains ESD sensitive ports. When installing equipment, follow ESD Safety Procedures. Electrostatic discharges might cause damage to the equipment.

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

Installation and Maintenance

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.

Exceeding the maximum rated AC input voltage could result

Caution

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.
