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 line: input positive pole (connected to the positive battery)
Black line: input negative (connected to the battery negative)
Yellow line: 24V output is positive (connected to the positive pole of the load)
Blue line: output negative load negative
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.
