PR Series – Linear Laboratory Power Supplies

Description

APPLICATIONS:

The PR Series SCR Pre-Regulated Linear Power Supplies are high reliability sources providing high power, stable output regulation, very low noise, and very low output ripple.

They are ideally suited for laboratory applications and in systems where both versatility of operation and a stable output regulation are required. The PR Series units operate as Constant Voltage/Constant Current Power Supplies with automatic crossover.

The PR Series offers stable DC Power in bench-mount configuration, or as 2U (3.5”) to 5U (8.75”) High, 19” Full Rack Design for power ranging from 300W to 3000W, respectively.

*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.

Load Regulation:
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.

Line Regulation:
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.
