Intelligent power supply demands have been increased in recent years especially in Robotic Charging, Remote Installation and Ultra High-Power because these applications not only needs to Control output power but also monitor the entire the system stability. In response, MEAN WELL launched multiples digitalized product such as NPB Charger, HEP-2300, NCP-3200 and SHP-10K Series with PMBus or CANBus to fulfill application demands.
These protocols can R/W the current operating status and information. Supported information is as follows: Output voltage, current and internal temperature, alarm and status, system-configuration, and adjust the charging curve.
