Protective Functions; Undervoltage Protection - VOLTCRAFT PSW 1000 Série Notice D'emploi

after connection of the inverter to the voltage source (e.g. a car battery), you may take
the inverter into operation:
• Connect a consumer to the mains socket of the inverter.
The rated power of the consumer (see rating plate on the consumer or in its operat-
ing instructions) must not exceed the output of the inverter.
• Switch the inverter on via the on/off switch (switch position "I").
If connected correctly, the "Power" LED will now light up and thus indicate correct operation
of the inverter. The consumer is ready for operation.
• The "Fault" LED will light up at overload, overtemperature or undervoltage recognition.
• To switch off the inverter, put the on/off switch in the "O" position.

8. PrOTECTIVE FuNCTIONS

a) undervoltage protection
The inverter emits an alarm sound when the input voltage drops below a specific value:
12 v inverter: voltage drops below 10.5 v/DC (tolerance ±0.5 v/DC)
24 v inverter: voltage drops below 21.0 v/DC (tolerance ±0.5 v/DC)
If the input voltage drops further, the inverter and the connected consumer are switched
off. This protects, e.g., a car battery that is used to operate the inverter, from harmful deep
discharge.
12 v inverter: voltage drops below 10.0 v/DC (tolerance ±0.5 v/DC)
24 v inverter: voltage drops below 20.0 v/DC (tolerance ±0.5 v/DC)
The "Fault" LED will light up if the inverter recognises undervoltage. In this case, switch
off the inverter via the on/off switch.
