DUAL VARIABLE OUTPUT

(INDEPENDENT AND TRACKING)

0 to ± 16 volts dual, 0 to 2 amps     TESTRONIX 35B

0 to ± 32 volts dual, 0 to 5 amps     TESTRONIX 93C

0 to ±32 volts dual, 0 to 2 amps      TESTRONIC 93B

OUT PUT VOLTAGES : Two independent (both positive or both negative or, one positive and one negative) output voltages of different values or of same values are available in independent mode of operation. Two tracking output voltages of equal value and opposite polarities are available in dual tracking mode of operation. Independent or dual tracking mode is selected by front panel control. The output voltages are continuously adjustable by coarse and fine front panel controls. Two output voltages are continuously displayed on 2 separate 3 ½ digit meters with accuracy of ± 0.5 ± 2 least counts. (Meters have 3 digit in model 930). Meters have LED displays of 12.5 mm height. Output voltages can be floated on any live voltage or any of the terminals of the output voltage can be grounded to get positive or negative voltages.

LOAD CURRENT : Load currents of both the outputs are displayed on two separate 3 ½ digit meters with accuracy of ±0.5% ±2 least counts. (Meters have 3 digits in model 93C). Meters have LED type of displays of 12.5mm height. Maximum values of output currents can be limited from less than 10% to 100% of the full capacity by continuously adjustable coarse and fine controls.

PROTECTION : Short circuit and overload protected. Constant voltage, constant current type of regulation provides constant voltage if load current is less than the current limit setting. If load tries to draw more current than the value of current limit setting, current becomes constant at the limit setting and output voltage comes down to limit the current at the current limit setting value.

REGULATION : ±0.05% from no load to full load and for ± 10% variations in input mains voltage.

RIPPLES : Less than 3 mill volts r.m.s.
