1. GENERAL INFORMATION
1.1 INTRODUCTION
Lambda Americas ALE series 203 and 303 are state of the art switch mode high voltage
power supplies, designed primarily for capacitor charging applications such as laser sys-
tems, modulators, and pulse forming networks. They can also be used in many continu-
ous DC applications including beam power for magnetrons, gyrotrons, klystrons and
electron beam loads.
The 203L and 303L Models are fully instrumented with front panel meters displaying
output voltage and current, status LEDs, a key switch for OFF, LOCAL or REMOTE op-
eration, HV ON/OFF push-button switches, and a counting dial for output voltage ad-
justment. The rear panel features external interlock, external inhibit, remote control and
slave (parallel operation) control connections.
The 203S and 303S Models can only be operated by remote control and feature only
front panel status LEDs. 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. As many 203 or
303 supplies as required, can be connected in parallel to provide greater output power.
