Constant Voltage / Constant Current Power Supply Up to 2500W
The PR Series power supplies provide SCR pre-regulated linear output with high power, good regulation and low ripple. They find application both in the laboratory and in systems where both versatility of operation and a high degree of regulation is required.The PR Series operates both as constant voltage (CV) and constant current (CC) mode power supply depending on the load and control settings. The mode status can be observed by panel indicators.

*220VAC 50/60 Hz 1 Phase Standard
Input: 115 VAC or 220 VAC ±10% 50/60 Hz Single Phase depending on the model.
Output: See specific model in table.
The output is floating and either side may be grounded.
CV Mode: 0.01% of the maximum rated voltage for a full load step.
CC Mode: 0.25% of the maximum rated current for full load voltage compliance.
CV Mode: 0.01% of maximum rated voltage for a line change within specified input voltage range.
CC Mode: 0.01% of maximum rated current for a line change within specified input voltage range.
Ripple: ≤1 mV RMS.
Response Time: The output voltage is within regulation limits in less than 100 microseconds for a ½ load step. The output voltage will remain within regulation limits for input line step within specified voltage range.
Remote Sensing: Units provided with remote sense terminals at the rear for regulation at the point of load.
Remote Programming: All units are voltage programmable at approximately 1000Ω / Volt.
Series / Parallel Operation: Two or more units may be operated in series. Two units of the same voltage and current may be operated in parallel.
Temp. Coef.: 0.02% / °C
Stability: Better than 0.05% / 8 hours at constant line, load and temperature after ½ hour warm up.
Operating Temperature: 0°C to +60°C at any combination of line, load and temperature without the need for external cooling.
Terminations: Barrier strip terminals are provided at the rear for AC input, output, sensing, remote programming, slaving and ground.
Protection: The power supply is protected by a fuse in the input line. 8¾” model is protected by a circuit breaker. The power supply is protected by means of a fully adjustable current limiting circuit.
Panel Controls: Voltmeter, Ammeter, 10 turn voltage control, 10 turn current control, pilot light, ON/OFF switch and five way binding posts. The voltage and current control is fully adjustable from 0 to Full Range by means of 10 turn panel potentiometers.
Finish: The standard front panel finish is light blue.
