The ContinuousWave (CW) Series of AC power sources provides clean single phase power at an impressive price/performance ratio. These compact switch mode sources come in two series, manual (CW-M) or programmable (CW-P) with standard IEEE-488.2 and RS 232 control. Both the manual and programmable models can be field configured for three phase operation or used in parallel (including parallel - three phase) with optional factory supplied cables. Both series have three power levels, 800 VA, 1250 VA and 2500 A. The 800 VA and 1250 VA models are 2U (3.5") high and allow the unit under test to be connected to the front or rear panel. The 2500 VA model is 3U (5.25") high with rear panel output connections. All models can be operated in a benchtop or rackmount configuration.The front panels have two bright four digit, seven segment displays. The 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 (45 to 1000 Hz with option H, CW-P only). Custom output voltages are available (consult factory for details).
