PR570 Condensed Specifications

Isolated Output - VOLTAGE: 0-140 VAC typical at 117 VAC input, continuously variable. CURRENT: 3 amps continuous; 3-4 amps, 470 watts maximum intermittent use (5 minutes on, 5 minutes off). OUTPUT LOADING: Less than 12 volts drop in output with 3 amp load at 120 VAC.

AC Volts Functions - AC LINE VOLTAGE TESTS: Measures and displays the selected voltage: Hot to External Earth Ground, Hot to Safety Ground or Hot to Neutral. RANGE: 0-150 VAC. ACCURACY: ±3% reading ±2 counts, calibrated at 117 VAC. RESOLUTION: 1 volt. PROTECTION: 240 VAC. ISOLATED OUTPUT VOLTAGE: Measures and displays voltage at isolated output. Same as Line Voltage Tests.

Output Current Monitor - MEASUREMENT: True Power. RANGE: 0 to 470 watts. ACCURACY: ±5% of reading, ±2 counts. RESOLUTION: 1 watt.

Adjustable Current Trip - RANGE: 0-4 amps. ACCURACY: ±10% of reading, ±20 mA. RESOLUTION: Adjustable in 10 mA increments. TRIP TIME: 0.3 seconds max. with 200% overload.

Hot Chassis Test - MEASUREMENT: Ties high and low lead of primary together and measures leakage to exposed metal with power off. RANGE: 0 to 1999 µA. ACCURACY: ±3% of reading, ±2 counts. RESOLUTION: 1 µA. PROTECTION: 150 mA RMS, 150 V max.

Safety Leakage Test - MEASUREMENT: Referenced to either side of isolated output jack. (Automatically toggles high and low line and opens and closes safety ground and displays highest reading.) RANGE: 0 to 1999 µA. ACCURACY: ±3% of reading, ±2 counts. RESOLUTION: 1 µA. PROTECTION: 150 mA RMS, 150 V max. CAL CHECK: 100 µA, ±3% of reading, ±2 counts with isolated output at 120 VAC.

Protection - AC INPUT: 4 amps, type 3AG slo-blow fuse. ISOLATED OUTPUT: Adjustable current trip, 1 to 4 amps.

General - SIZE: 6" x 11.5" x 12" (15.2 x 25.4 x 29.2 cm) HWD. WEIGHT: 22 lbs. (10 kg). POWER: 105 to 125 VAC, 60 Hz, 4 amps idle current with no output load.
