Output voltage and current limit adjustment
The output voltage and output current limit of the power supply can be adjusted as using the multi-turn
potentiometers accessible from the front panel.
Both voltage and current can be adjusted from zero to the maximum value. Maximum 800W output power is
available within the adjustment range.
The power supply includes 16 pre-programmed output voltages that are set by the code switch. See the setting
table for this unit. Any of these 16 different voltage settings can be taken in use and additionally be adjusted within
±5% using the trimmer on the front panel. See the instructions for choosing the programmed voltage and the fine-
tune adjustment.
LED
An orange LED indicates a healthy power supply output voltage.
Overcurrent protection
The output of the power supply is protected against overcurrents and short circuits by an automatic, self-resetting
electronic current limiter.
Series/parallel connection
Parallel operation: No restrictions, passive load sharing
Series operation: Series operation: Up to 500V total voltage. For more information about use with an AI or S
option, ask the manufacturer.
Warning
Dangerous voltages, capable of causing death are present in the power supply. Do not remove the cover. There
are no operator serviceable parts inside the unit. Refer servicing to qualified service personnel only.

Alarm relay (Option R)
On models with an alarm relay, the alarm relay output indicates whether the output voltage is healthy or not. The
alarm signal is activated in case of an AC failure or charger failure. Both normally closed signals and normally
open contacts are available.
