Input: 105-125 Volts AC 50 to 60Hz single phase.
Output: See specific model in table
The output is floating and either side may be grounded.
Load Regulation: 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 1mv RMS
Response Time: The output voltage is within regulation limits in less than 100 ms for 1/2 load step.
The output voltage will remain within regulation limits for line step from 105 to 125 to 105VAC.
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.
Operation Temperature: 0C to +50C at any combination of line, load and temperature including continuous operation at 125VAC 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 detachable wire line cord 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.
