General description
The KL620 series OBC has been designed for larger power charger application, three phase AC input, 400VDC-700VDC output. It can use in bus, commercial truck, and can withstand harsh environments (vibration, thermal shock and extreme temperature ranges).
The KL620 series is design as Fan cooling or liquid cooling with IP 67 enclosure .
The KL620 series is programmable with the independent control unit inside, this make it flexible to achieve the individual needs of customers.
With the multi grid adaptability and the independent control unit , it is in full compliance with international standards such as SAE J1772 and EN61851.
The processor-driven charging algorithms provides optimal results in efficiency and it contributes to a longer life of the battery charger and the HV battery.
Main Feature
• Compliance with three phase AC input .
• Compliance with SAE J1772 and EN61851.
• Compact and lightweight construction.
• Constant power and constant current charging capable.
• Vibration-resistant and IP67 for on-board use.
• Firmware up-gradable over CAN bus.
• DC High Voltage Interlock Loop (HVIL) protection.
• Precise and efficient charging power.
