The SV Series SCR Pre-Regulated High Voltage Linear Power Supplies are high reliability sources with high voltage ranging from 600V to 1000V, relatively high power, and extremely stable output regulation. Their very low ripple and very low noise make them the preferred “Down Hole” power sources, as well as fixed and towed array systems power. The SV units have an adjustable current limiting circuit which provides output load protection. They are ideally suited for laboratory applications and in systems where both versatility of operation and a high degree of regulation are required.

The SV Series offers stable DC Power in 2U (3.5”) to 8U (14”) High 19” Full Rack Design for power ranging from 350W to 6000W (respectively) at 600-1000 Volts range.

Output: See specific model in table.
The output is floating and either side may be grounded.

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 within specified input voltage range.

Ripple: ≤3 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.:  0.01% / °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: AC line cord is provided for 3½” and 5¼”  models. All other models have barrier terminal strip for AC input.Barrier terminal strips are provided at the rear for output, sensing, remote programming, slaving and ground.

Protection: The power supply is protected by a fuse in the input line. 8¾” models and above are 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 and ON/OFF switch. 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.
