SPECIFICATIONS FOR NI-81030D
S No. Description
Input Voltage 230V +/- 10% AC, 50Hz.
Output Voltage 0-30V DC, Continuously variable with fine and coarse variation.
Output Current 0-5 Amp, Continuously variable .
Mode of operation Constant voltage mode: When the load current is less
than the current limit set by current control.
When the load current limit requirement is more
than the current limit set by current control,
automatic switch over from constant voltage mode
to constant current mode takes place.
Load Regulation +/- 0.01% from no load to full load.
Line Regulation +/- 0.01% for +/- 10% variation in inputline voltage.
Ripple voltage Less than 1mV rms.
Meters Two digital meters provided to measure voltage and current with switch selection.
Meter Accuracy +/- 0.2% of reading, +/- 2 least counts.
Protection Continuous overload and short circuit protection.
