6.6 REMOTE MONITORING OF OUTPUT VOLTAGE AND CURRENT

The J1 connector, located on the rear panel provides analog signals for monitoring the Output Voltage and Output Current. Selection of the voltage range between 0-5V or 0-10V is made by setup switch SW1-4. The monitoring signals represent 0 to 100% of the power supply Output Voltage and Output Current. The monitor outputs have 500 ohm series output resistance. Ensure that the sensing circuit has an input resistance of greater than 500 Kohm or accuracy will be re- duced.

Refer to Table 6-5 for the required J1 connection, SW1-4 setting and monitoring voltage range.

	Signal	Signal function	J1 connection		Range	SW1-4
	name		Signal (+)	Return (-)
	VMON	Vout monitor	J1-11	J1-12	0-5V	Down
	IMON	Iout monitor	J1-24

	VMON	Vout monitor	J1-11	J1-12	0-10V	Up
	IMON	Iout monitor	J1-24

Table 6-5 Monitoring signals setting

Notes:

1.Radiated emissions, RCC requirements:

2.Front panel encoders operation:

FCC requirements for radiated emissions; use a shielded cable for the analog control signals. If using unshielded cable, attach an EMI ferrite suppressor to the cable, as close as possible to the power supply.

In Remote analog mode, the output voltage and cur- rent can’t be set by the VOLTAGE and CURRENT encoders.

3. Front panel PREV button:

Use the PREV button to display the Output Voltage and Current setting, as defined by the encoders or digital communication.

4. Communication:	In Remote analog mode, all power supply parame-
	ters can be programmed and readback via the
	communication port, except the Output Voltage and
	Current setting.
