designed as a Constant Current (CC) and Constant Voltage (CV) source for use in laboratories, industries and field testing. With compact size, it provides DC output voltages for Analog and Digital testing. They provide high regulation and stability with either Digital 3-digit display for voltage & current is provided to read the values, the unit is equipped with coarse and fine controls for adjusting the voltage and current outputs These two parameters can be switched to display either voltage or Current. excellent line and load regulation and is provided with protective circuits to ensure trouble free operation. All the outputs are protected from short circuits and overload.
Technical Specifications
Input Power: 230VAC+/- 10%
Frequency: 50 3 Hz.
Line Regulation: Better than 0.05% for the Input variation of +/-10%
Load Regulation: Better than 0.05% from no Load to full load.
The output voltage is continuously adjustable by coarse and fine controls and is displayed on 3 digit, LED display of 12.5 mm height with accuracy of 0.5% 2 least counts. (Voltmeters in models 30C/ 30D/ 92A/ 92B/ 92C/ 92D/ 36A/ 36B/ 36C have 3 digit displays.) Output voltage can be floated on any live voltage or any of the two voltage terminals can be grounded to get positive or negative voltage.
LOAD CURRENT
Load current is displayed on 3 digit, LED display of 12.5mm height, with accuracy pf 0.5% least counts. (Current meters in models 30C/ 34C/ 36C have 3 digit displays.) Maximum value of output current can be limited from less than 10% to 100% of the capacity by continuously adjustable coarse and the controls.
PROTECTION
Short circuit and overload protected. Constant voltage constant current type of regulation provides constant voltage if load current is less than 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 limit setting value.
REGULATION
0.05% from no load to full load and for 10% variations in input mains voltage.
