  • Character

1.Main Circuit board: using fireproof board

2.Enclosure/Shell: The aluminum casing with shielding function reduces the conduction and radiation interference to peripheral equipment under the condition of heat dissipation.

3.Technology: Adopt high-frequency inverter technology and ISOLATED circuit design. The isolated converter is much more reliable and stable than non-isolated circuit design.

4.Input range: Support wide range input : 40~90V DC, which can meet the input of different battery voltage levels on different electric vehicles. Such as 48V/60/72Vdc Battery bank.

Short circuit protection: When the output is short circuited, the converter stops working, and automatically recovers after the short circuit is eliminated;

Over current protection: When the output current reaches the protection current value, the converter stops working;

Over-temperature protection: When the isolated dc-dc converter reaches the set temperature point, it will enter the automatic protection function, and resume the work after the temperature is drop. 

Under voltage protection: below 42V converter does not work

 

Connector definition

Red cable: input positive pole (connected to the positive battery)

lack cable: input negative (connected to the battery negative)

Green cable: ACC line Connect to ACC switch If there is no ACC switch, it can be directly connected with the input positive red line.

Thick yellow cable: The output is positive (connected to the positive pole of the load). The ACC line and the input are connected to have an output.

Blue cable: output negative (connected to the battery negative) Input negative and output negative can also be connected together for public use

Attention!!!! 

It is forbidden to connect the leads of the converter. Please confirm the function of each line and re-wire to avoid damage to the converter.

  • Application

1.Suitable for power conversion of various electric vehicles such as forklifts, electric handling vehicles, electric tour buses, electric golf carts, and elderly scooters.

2.The isolated dc-dc converter can work as an power unit to supply the power for electric vehicles instruments, accelerators, lights, etc

3.The isolated dc-dc converter suitable for all kinds of harsh environments. It is strong adaptability for low temperature, high temperature, dust, vibration environment with stable and reliable operation. It is suitable for occasions with high safety and low interference to the back-end electrical appliances also.
