The CSV 300 power supply is used to supply 12 volt devices such as submersible pumps, fans, lights and similar devices via a switching power supply (12 V with 24 A/300 VA). No external phono screen is required as the output voltage is sieved. The CSV 300 is particularly suitable for caravans that are mainly connected to the 230 volt network and only supply consumers from the vehicle battery for a short time. The switching between the supply from the vehicle battery and the (preferred) 230 volt power supply is automatically as soon as the mains voltage is present. No charging function. There are 5 separately fused 12 volt circuits and a 230 volt power distribution with preparation for 230 V circuit breakers available. Voltage: 12 V, 24 V, 230 V. Colour: blue. Dimensions (W x D x H): 225 × 210 × 85 mm. Weight: 1.5 kg.
