Acopian Power Supplies models may be programmed through their voltage ranges by means of external resistance. Models with adjustable current limiting have a constant-voltage/constant-current crossover characteristic, and so may be used as current regulated power supplies.

Voltage programmable using resistance.

SPECIFICATIONS

Input Voltage: 105-125 VAC, 50-400 Hz, single phase.

Regulation, Ripple (constant voltage operation): Load Regulation: ±0.005% or 2 mV, whichever is greater. Line Regulation: ±0.005% or 2 mV, whichever is greater. Ripple: 0.25 mV rms.

Regulation, Ripple (constant current operation): Load Regulation: ±0.2% or 5 mA. Line Regulation: ±0.1% or 2 mA. Ripple: 0.1% rms.

Remote Voltage Sensing: Provision for sensing the output voltage across the load, to compensate voltage drops in output wiring, is a standard feature.

Remote Voltage Programming: The output voltage of all models may be controlled by means of external resistance connected in series with the -S lead.

Voltage Programming Coefficient: See Output Specs. Calibration tolerance, ±2%.

Current Limiting/Programming: Models with fixed current limiting have a rolloff characteristic with automatic recovery. All others have current limiting with a constant-voltage/constant-current crossover characteristic.

Polarity: Output is floating; either positive or negative terminal may be grounded or floated up to 300 volts above ground.

Controls: Coarse and fine voltage adjustments, and the current limit adjustment, are located at the rear of the assembly.

Temperature Coefficient: 0.02%/°C. (Typical).

Ambient Operating Temperature: -20 to +71°C.

Storage Temperature: -55 to +85°C.
