The BK Precision 1655A Isolated-Variable AC Power Supply offers continuously variable output voltage from 0 to 150 VAC. It has a built in dual-purpose meter measures output voltage from 0 - 150 V and output current from 0 - 4A. Load calculations is not required if the measurement is made at the standard value of 120 volts. The 0 - 2 A and 0 - 4 A current scales are also calibrated as direct reading 0 - 24 VA and 0 - 480 VA scales. The 1655A 0 - 5mA (0 - 5000 µA) leakage scale is expanded in most commonly used 100 - 500 µA portion, compressed to 5 mA full scale. Overload protected. Specifications. Output Isolation: Leakage less than 0.1mA (25C, 50% relative humidity). Voltage Adjustment Range: 0 - 150 VAC, with input at 120 VAC. Voltage/Current Sensing: Sine wave average, calibrated in RMS. Maximum Current (Isolated): 3A continuous, 4A intermittent (0 - 130 V), Intermittent not to exceed 4 minutes at 4 A followed by 5 minutes at 1 A max.. Meter Scales Voltage: 0 - 150 V. Meter Scales Current: 0 - 2 A, 0 - 4 A. Meter Scales Volt-Amps (Voltage Set to 120): 0 - 240 VA, 0 - 480 VA. Meter Accuracy Volts: ±5% of full scale (calibrated @ 120VAC). Meter Accuracy Current: ±5% of full scale.
