RA | Constant Voltage Linear Power Supplies |
| 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. |
