Elgar
CW801P 800VA AC Power Source
The Elgar CW801P 800VA AC power source provides clean single phase power at an impressive price/performance ratio. This compact switch mode source is programmable with standard IEEE-488.2 or RS-232 control. It can be operated in a benchtop or rackmount configuration.
Power Factor Corrected (PFC) universal input voltage allows maximum power to be delivered from an AC outlet without the user selecting the range. Fully rated current is delivered for either output voltage range of 135 VAC or 270 VAC over a standard frequency range of 45 to 500
Hz. The Elgar CW801P can be paralleled to provide extra power. A separate output-on switch controls power to the load. Remote voltage sense is standard. Transformer coupled output is protected against overvoltage and overcurrent. The unit is also protected against
over temperature conditions. A two-speed fan results in quieter operation at lower power levels.
