ESCRIPTION
The output is electronically protected against no-load, overload and short circuit. In case of an overload or
short circuit, the device will operate intermittently (hiccup mode).
The device can supply resistive and inductive loads.
Avoid loads with large input capacitances. If the capacitive load is higher than the values specified, the device
operates in an intermittent mode (hiccup mode). See short-form data table for maximum values.
The output voltage is fixed and can not be adjusted.
The device is equipped with an over-temperature protection. In case of a high temperature, the output shuts
down and starts automatically after cooling off.
The device is equipped with an input under-voltage protection. If the input voltage is too low, the device does
not start or switches off.
In case of an internal defect, a redundant circuit prevents the output voltage from becoming excessive or
dangerous.
The device is equipped with a green DC-OK LED, which is visible from the outside of the device.
