Dometic SMART-IN SM400-12 Instrucciones De Uso página 12

5 Intended use
The device is intended to supply 230 V to connected appliances generated from 12 V or 24 V input voltage. The de-
vice is designed to be used in motorhomes, campervans and coaches.
The model line includes two types of devices:
• The SM400-12, SM600-12, SM600-24, SM1000-12 and SM1500-12 models are inverters with modified sinu-
soidal wave output.
• The SP400-12 , SP600-12, SP600-24, SP1000-12, SP1500-12, SP1500-24, SP3000-12 and SP3000-24 models
are inverters with pure sinusoidal wave output.
The SP1000I-12, SP1500I-12 and SP2000I-12 models are featuring an integrated priority function (IVT) and a fuse-pro-
tected input (IEC) socket for the external power supply connection.

used, and has received safety training to identify and avoid the hazards involved.
7 Technical description
The device has two main circuit stages to convert the 12 V DC or 24 V DC input voltage to AC output voltage. The
first stage consists of an isolated high frequency DC/DC converter to convert the 12 V DC or 24 V DC input voltage
to an output voltage up to 400 V DC. The final stage consists of a H-bridge that converts the DC high voltage bus to
230 V AC voltage.
The device has the following main features:
• Low consumption.
• Galvanically isolated input and output for increased safety.
• Temperature-controlled fan speed for quiet operation.
• Integrated priority switch between external mains network and the battery.
• Ready for On/Off remote control.
