Charging Curve (For charger type or setting HEP-1000 to charger mode)

  • By default, the HEP-1000 operates in power supply mode, and it can be configured to charger mode by PMBus, CANBus, or SBP-001.
  • By factory default, this charger performs the default curve which can be programmed via PMBus and CANBus.
  • To accommodate the parameters of the charging curve, SBP-001, the smart battery charging programmer designed by MEAN WELL, and a personal computer are needed. Please contact MEAN WELL for details.
