Application

The RA Series of Power Supplies are all silicon, relatively high power, and tightly regulated. They find application both in the laboratory and in systems where both versatility of operation and a high degree of regulation is required. Adjustable solid state current limiting provides load protection.

Constant Voltage Linear Power Supplies


Specifications

Input:105-125 Volts AC 50 to 60 Hz single phase.
Output:See specific model in table.
The output is floating and either side may be grounded.
The voltage level is fully adjustable by means of a 10 turn potentiometer located on the front panel.
Load Regulation:0.01% of the maximum rated voltage for a full load step.
Line Regulation:0.01% of the maximum rated voltage for a line change from 105 to 125 or 125 to 105 VAC.
Ripple:Less than 1 millivolts RMS.
Response Time:The output voltage is within regulation limits in less than 100 microseconds for a 1/2 load step.
The output voltage will remain within regulation limits for a line step from 105 to 125 or 125 to 105 VAC.
Remote Sensing:To allow for point of load regulation all units are provided with remote sense terminals at the rear.
Remote Programming:All units are voltage programmable at approximately 1000 /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%/ degree C.
Stability:Better than 0.05%/8 hours at constant line, load and temperature, after 1/2 hour warm up.
Operating Temperature:0°C to +60°C at any combination of line, load and temperature including continuous operation at 125 VAC and full load 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. 8-3/4" models have a circuit breaker. The output of the supply is protected by means of the fully adjustable solid state current limiting feature.
Size:See specific models for panel heights. Width is 19" rack panel mountings. Depth is 16-1/2" behind the panel, except 8-3/4" models which are 22" deep.
Finish:The standard front panel finish is light blue. Markings are black.
Panel Controls:Voltmeter, ammeter, 10 turn voltage control, current limit control, pilot light and on/off switch.
