Product description

It is a miniaturized, versatile, and ultra-wide voltage intelligent charger. It utilizes a fully digital control design with automatic battery voltage detection technology, with five key features including intelligent, versatile, user friendly, safe and compact. This model can pair with MEANWELL´s SBP-001 programmer for digital configuration, such as select 2/3 stage charging adjust charging voltage/current, and set charging cycle time to protect battery lifetime. Through the user-friendly DIP S.W. on front panel, user may also directly adjust 2/3 stage charging, current (50-100%), and select between the 4 types of preset charging curves. In addition, a CANBus communication protocol is built in to meet professional applications, which allows remote controlling and monitoring for the status of the charger.

FAQ When the cell voltage (3.65 V) is reached, the charger must be manually disconnected from the terminals. Disconnecting the charger from the mains only will cause the cell to discharge it.
