ANALOGUE REMOTE CONTROL (Single PL-P models only)
Non-isolated inputs and outputs to set voltage and current limit
Control input and output
scaling:
Rear panel control inputs (CV and CC) permit external 0V to 5V or 0 to10V
signals to set 0 to 100% of rated output voltage and current.
Set values of 0 to 100% of rated output voltage and current generate
0 to 5V signals at the rear panel V
out
and I
out
outputs.
These signals are referenced to the positive output.
Control input accuracy:
Voltage: 0.3% ±10mV. Input impedance 100kΩ; protected to 60V.
Current: 0.5% ±5mA. Input impedance 64kΩ; protected to 60V.
Control output accuracy:
Voltage: 0.3% ±10mV
Current: 0.5% ±5mA.
Output impedance: 125Ω; output short-circuit protected.
Remote Off:
Rear panel socket allows a switch closure or logic low to turn output off.
