CW ARC LAMP LASER POWER SUPPLIES

General Specifications and Type


There are six Standard Models of CW Power Supply currently available. Operation is identical. Specifications differ because of the Line Input Voltage. For each line voltage a product is available in two sizes, '4U' high and '3U' high.

By Product Type these are:

 

'4U' high

and

'3U' high

.

Temperature - '4U' and '3U'

Continuous in an ambient of 0C to 60C with appropriate derating above 35C ('4U') and 32C ('3U').

.

 

Safety (all Types)

All control circuitry and wiring has full galvanic isolation from the line, and are low voltage. Should the lamp fail to ignite the trigger and boost voltages are removed from the output terminals. The build standards comply with EN61010-1 and conform to the requirements of the Low Voltage Directive 73/23/EEC and carry the CE Mark.

An appropriate EMC Filter is fitted. Units comply with the Emission and Immunity Standards EN50082-2 and EN50081-2 (Class A).

.

 

Protection

Protection on the line input is by VDE rated circuit breaker. Output protection is included in the event of a lamp failure or connection to earth. Thermal protection is included against overload.

.

 

Front Panel Controls

MCB line breaker.
ON-OFF Rocker switch (with automatic lamp ignition)
10-turn potentiometer for lamp current control.
3 1/2 Digit LED Display of lamp current.
Push Switch selecting 'Standby', Remote or potentiometer control of output lamp current.
