Remote Monitoring of Output Voltage and Current

Remote Monitoring of Output Voltage and Current

Readback The J2 connector on the rear panel provides access to calibrated readback signals for Signals remote monitoring of the output voltage and current. Rear panel switches SW1-5 and SW1-6 allow you to select either a 0-5 Vdc or a 0-10 Vdc range for the output. The

readback signal represents 0 to 100% of the power supply’s output.

See Table 4.3 for the required J2 connections and switch settings for remote monitoring of readback signals with 0-5 Vdc or 0-10 Vdc outputs. Use shielded pair wiring (20 to 24 AWG) and ground the shield to J10 sense connector terminal 1 (return sense) or to the chassis.

Table 4.3 Power Supply Settings for Remote Monitoring of Readback Signals

	Readback Signal	J2 Connection	J2 Connection	Switch SW1 Setting
	Readback Signal	Signal (+)	Return (–)	Switch SW1 Setting
		Signal (+)	Return (–)
	Output Voltage	J2-10	J2-9	SW1-5 OFF (OPEN)
	(0-5 Vdc)
	Output Voltage	J2-10	J2-9	SW1-5 ON (CLOSED)
	(0-10 Vdc)

	Output Current	J2-12	J2-11	SW1-6 OFF (OPEN)
	(0-5 Vdc)
	Output Current	J2-12	J2-11	SW1-6 ON (CLOSED)
	(0-10 Vdc)

Note:Check the readback accuracy any time you reset switches SW1-5 and SW1-6. See Section 5. Calibration.
