1000W Isolated DC/DC Converter
1. Overview
TDC-320-12IG Series of 1000W Series DC/DC converter can be installed in electric cars to supply 12V low-voltage DC power to be used for low-voltage equipment. The output terminal can connect a backup 12V battery and DC/DC converter can manage the charging of the backup battery automatically. The casing is fully sealed, water-proof, automotive level temperature resistance and vibration resist. Connection diagram as illustrated below. The high voltage DC input of the DC/DC converter connects directly to the positive and negative pole of the battery pack and the DC output connects to the 12V backup battery, then export to all the 12V electrical appliances.
2. Basic Function
2.1 It can convert the high voltage DC to 12V low voltage DC
2.2 The charging of 12V backup battery can be controllable
2.3 Indicate the working status, fault code etc through DC/DC panel by LED
2.4 Protection function such as input low voltage protection, input reverse connection protection, DC/DC over-temperature etc.
2.5 Fully sealed, water-proof, no fans, natural convection air-cooling

300W DC-DC Converter
Features
1.Natural heat dissipation, efficiency more than 94%, significantly reducing the size of the radiator and heating value.
2.Available for constantly operation with heavy load.
3.Static low-power, can reduce battery consumption.
4.Steady output voltage with soft-start technology, no over-charge of output voltge on power-on.
5.Output over-current limitation
6.Output short-circuit protection. DC/DC converter is free from damage if connects output directly in short or long time, constant short-circuit permissible, and can automatically resume working after the short-circuit disapperars.
7.Fully Protection functions such as low-voltage protection, output over-voltage protection, circuit malfunction protection etc., can enhance the reliability of the circuit.
