HWD | Constant Voltage/Current 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. | |
| LoadRegulation: | See Table. Regulation is for a full load step. |
| Line Regulation: | See table. Regulation is 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 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 ohms /Volt except Model HWD400-0.5B which is programmable at 400 ohms/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 +50°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 output, sensing, remote programming, and ground. |
| 5 Way binding posts are provided on the front panel for output and ground. | |
| A seven foot 3 wire line cord provides for AC input. | |
| Protection: | The power supply is protected by a fuse in the input line. |
| The output of the supply is protected by means of the fully adjustable solid state current limiting feature. | |
| Panel Controls: | Digital Voltmeter, ammeter, 10 turn voltage control, 10 turn current control, pilot light and on/off switch, Five way binding posts. |
| The voltage level is fully adjustable by means of a 10 turn panel voltage adjust potentiometer | |
| Finish: | The standard front panel and chassis finish is light blue. Cover is dark blue. |
| Size: | 4-1/2" high x 8" wide x 14" deep. Two units can mount in a 19" wide x 5-1/4" panel. See option 10 and 11 below. |
