Product Description

Product Description

Feature

‌1.Externally Accessible Fuse‌
The externally accessible fuse design separates the fuse from the internal structure of the power supply, enabling direct replacement without disassembling the housing.

‌2.NO Switch Time
Compared to legacy models with a 0.03-second switching delay, ‌the new series achieves instantaneous switching‌, enhancing power conversion efficiency and stability.

‌3.Reverse Polarity Protection‌
Equipped with reverse polarity protection, ‌the power supply remains undamaged even if batteries are connected incorrectly‌, significantly improving operational safety

4.How to do cold start?

Connect the negative terminal of the battery and the negative terminal of the load

Need to connect it with another cable, connect it for a moment and it will switch, then remove the cable.
