Temperature Protection Switch; Overload Protection - VOLTCRAFT SWD Série Notice D'emploi

The voltage threshold for the undervoltage cut-off function is set in the factory but can be customised
with an optional display remote control (e.g. FB-02 SWD or FB-03 SWD). Setting is described in the
remote control's operating instructions.
The reactivation threshold is fixed in the factory and cannot be changed.

Temperature Protection Switch

The converter is equipped with an output- and temperature-controlled device ventilator. Where the tem-
perature inside the device is too high, the converter automatically switches off the output for reasons of
security. Do not switch off the converter and let it first reach normal operating temperature. The output is
reactivated automatically.

Overload Protection

The DC-AC converter cuts off automatically in case of an overload. Overloads may occur when the per-
manent output or power intake are exceeded or when there is a short circuit on the output.
The converter is equipped with an automatic reactivation (soft start) after overload. This restart especially
makes sense in case of consumers with a high start-up power. If reactivation is not possible even after
repeated attempts, the consumer is not suitable for operation at the converter.
The output is switched on automatically when the overload or short circuit at the overload was removed.
General information on operating alternate current consumers on DC-AC converters
In principle, you can operate all 230 V consumers on DC-AC converters. However, on order to estimate
the power requirement and the corresponding reserves, it is important to know some properties of typi-
cal 230 V consumers.
Many 230 V consumers require a much higher start-up output than the permanent output indicated on
the type plate.
The start-up output does not play a major role with mains operation, because the corresponding power
reserves are always available. However, converters are limited in their output and can only supply the
indicated peak output for short periods of time. When the start-up output of a consumer is higher than the
peak load, the DC-AC converter is not suitable for this consumer.
Example: A small compressor-operated refrigerator with a permanent output of approx. 50 W requires up
to 500 watt in the compressor start-up stage. This refrigerator requires a converter with a peak output of
at least 500 W.
Other Examples:
- Light bulb approx. 1 sec. up to 8 times higher start-up output
- Refrigerators approx. 3 sec. up to 10 times higher start-up output
- TVs approx. 1 sec. up to 10 times higher start-up output
