6.6 REMOTE MONITORING OF OUTPUT VOLTAGE AND CURRENT

The J1 connector, located on the rear panel provides analog signals for monitoring the Output Volt- age 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 reduced.

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

Notes:

1.Radiated emissions, FCC requirements: FCC requirements for radiated emissions; use 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.

2.Front panel encoders operation:

3.Front panel PREV button:

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

Use the PREV button to display the Output Voltage and Current setting defined by the encoders or communica- tion.

4. Communication:

In Remote analog mode, all power supply parameters

 

can be programmed and readback via the communication

 

port, except the Output Voltage and Current setting.
