User Manual Content

This User’s Manual contains the operating instructions, installation instructions and
specifications for the ALE 802 series high voltage power supply. The instructions refer to
standard power supply models, and include checkout, installation, and operation of the 802
series. Suggestions and requirements for connecting AC power, load cables and signal
cables are given. Various operating modes and programming modes are described.

The model 802 is just one model in a broad family of HV power supplies covering the power
range from 500J/sec to 30kJ/sec in a single package, and to 1MW and beyond in parallel
systems. For more information please visit our web site at:

NOTE

This manual contains information, instructions and diagrams which apply to standard

constructions. If special features or modifications have been installed, the instructions

specific to that modification are contained in Addenda and take precedence if conflicts

exist. Please take care to refer to the correct information for your unit.

Introduction

TDK-Lambda Americas ALE model 802 are state of the art constant current switch mode
high voltage power supplies, designed to rapidly and efficiently charge capacitors in laser
systems, modulators, pulse forming networks, and a broad range of pulse generator circuits,
without the need for a series current limiting resistor. They can also be used in many
continuous DC applications including beam power for RF devices such as magnetrons,
gyrotrons, klystrons and electron beam loads.

The 802 series utilize a high frequency IGBT based series resonant inverter topology which
operates as a constant current source. This makes the supply perfect for rapidly charging
capacitors which represent a challenging load for conventional HV DC supplies using
multiplier designs.

The 802 series is available with a choice of three different front panel configurations
designed to suit different applications and end uses. All models feature the same
comprehensive remote control interface which is detailed in Section 6.2.

The

802L

Model is fully instrumented with front panel meters displaying output voltage and

current, status LEDs, a key switch for OFF, LOCAL or REMOTE operation, HV ON/OFF
push-button switches, and a 10 Turn output voltage control. The rear panel features external
interlock, inhibit, remote control and slave (parallel operation) control connections.

The

802S

Model can only be operated by remote control and features only status LEDs and

a power switch on the front panel. The "S" Models have been designed to operate as a slave
unit to the "L" Models or in systems where local control is not a requirement.

The

802OEM

features a blank aluminum front panel and can only be operated by remote

control.

As many 802 supplies as required, can be connected in parallel to provide greater output
power.
