The Kepco OPS500B is a 500 Volt / 40 mAmp / 20 W DC Power Supply.
Kepco OPS Series Power Managers are high voltage 20-, 25-, and 35-Watt fast programmable power supplies, which can stabilize a voltage or current against the effects of load, source, or temperature changes, yet respond with agility to programming signals requiring swift changes in output. A built-in uncommitted amplifier can be used for summing, scaling, and programming by passive resistance.
Output voltage is controlled by a built-in fixed feedback resistor which senses the voltage at the negative output/sense terminal ; and by a 0-1mA control current connected to the input summing terminal, which may be externally generated or derived from the built-in uncommitted amplifier. This amplifier, together with a built-in 6.2V reference, allows for low-level, passive element control over the output. A 0-5K ohm rheostat substituted for the internal feedback will control the high voltage output linearly through its entire range; or feedback can be taken from a sensor to stabilize heat, speed, force, or other physical phenomena.
Output current is controlled by a built-in current sensing and feedback circuit, compensated to account for the shunting effect of the voltage feedback circuit. a recessed trimmer, accessible through the front panel on the OPS X models, will control current from 2% Io to 100% Io max.
For a wider current control range, the voltage control channel may be connected so as to sample the drop across an external current-sensing resistor to obtain current feedback. Based on a 10V sample, control can be exercised from approximately 1mA to maximum output current. The current control channel can be controlled externally by an analog voltage (0-1V for full scale current), or by a potentiometer divider across the internal reference. Control of current is referred to the plus output terminal.
