NOTES:
1. The power supply can be programmed to up to 108% of the rated output voltage and current.
However, it is forbidden to operate the power supply over its voltage and current ratings.
Performance is not guaranteed when operating the power supply above its ratings.
2. Communication: In the Remote Analog mode, power supply parameters can be programmed
and read back via the Communication port, except for output voltage and current settings.
3. To maintain the temperature stability specification of the power supply, the resistors used for
programming should be stable and low noise resistors, with a temperature coefficient of less
than 50ppm.
4. Radiated emissions, FCC requirements: FCC requirements for radiated emissions: use a
shielded cable for the Analog control signals. When using a non-shielded cable, attach an EMI
ferrite suppressor to the cable, as close as possible to the power supply.
5. Front panel PREV button: Use the PREV button to display the output voltage and current
settings defined by the Encoders or Communication.

Monitoring of Output Voltage (V_MON) and Current (I_MON)
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 between 0-10V is made
via the Front Panel or communication.
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.
CAUTION
Ensure that the sensing circuit has an input resistance of greater than 500 Kohm or accuracy will
be reduced.
Perform range selection as follows:
1. Press the CONF button. CONF (GREEN) LED illuminates.
2. Rotate the Voltage encoder until RANGE appears on the voltage display.
3. Rotate the Current encoder to set 5 or 10 (5V or 10V monitoring range). Press the Current
encoder for selection, display blinks once to acknowledge the setting.
4. Exit CONF menu by pressing the Back button or the CONF button.
