Elgar CW-M Series
1 INTRODUCTION
Elgar's ContinuousWave™ (CW) Series power sources deliver up to 1250 VA in a 2U
high (3.5 inches) rackmount chassis, and 2500 VA in a 5.25 inch chassis. This low
profile design is also suitable for benchtop use. The CW Series models have three
power ratings: 800 VA, 1250 VA, and 2500 VA. The switchmode, Power Factor
Corrected (PFC) design efficiently delivers clean AC power.
Voltage, current, and frequency settings are quickly adjusted from the front panel knobs
(10–turn potentiometers). Also, the sources can be programmed remotely from the rear
panel analog port. The output is protected against overvoltage, overcurrent, and over-
temperature conditions. They can be easily paralleled in the field with an additional
parallel cable. A two-speed fan results in quieter operation at lower power levels.
Key features of the CW Series AC power sources include:
•
High performance/value design
