TDK Genesys - Remote Monitoring of Output Voltage and Current

83-530-000 Rev J
7.6. 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 reduced.
Refer to Table 7-5 for 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 and connect shield to chassis (As
stud is provided near J1).
2. Front panel encoders operation:
In Remote analog mode the output voltage and current can’t be
set by the VOLTAGE and CURRENT encoders.
3. Front panel prev button:
Use PREV button to display the output voltage and current
setting defined by the encoders or communication.
4. Communication:
Remote analog mode, power supply parameters can be
programmed and readback via the communication port except
output voltage and current setting.
