NI DC-DC Converter

IpDCNI series DC/DC converter applies advanced technology and is configured specifically for electric vehicles. It is very suitable to supply power to the lamp and audio system as it is very stable and clean. The advantages of high efficiency, stability and compact size, are achieved by adopting the advanced high frequency technology. It is sealed by silica glue to get water and vibration proof, which ensures the stability of the vehicle in atrocious condition.

Current equalizer is built in, which makes converters work in parallel possible in order to enlarge the capability.

No arc design, which can be controlled by the key switch directly and no contactor is required.

Some DC/DC converters modules can be used in parallel directly to increase current.

Protections

Water and Vibration Proofed: All sealed by silica glue to get water and vibration proof, which is suitable for all kinds of condition.

Input reverse polarity protection: Shut down, auto-reset.

Water Proofed Fuse: Input or output fuse, simple wring.

No Arc: Input with no arc, can be controlled by key switch directly, without contactorn

Short Circuit: Shut down with little plus current, auto-reset, ensure the wire safety.

Superheating Cutback: Reduce output current if the temperature is over 65u00b0C, ensure the continuous power for your car.

Reverse Polarity: Electronic protection, auto-reset.

Input Low Protection: Shut down, auto-reset, prevent the battery from over discharging
