REC BMS | Adjustable Pre-Charge Delay


  • 11-68v Input Voltage; Compatible with 12, 24, 36 & 48v Systems
  • Installer-Adjustable delay; Can be set to 2, 4, 8 and 11 second delays.  Default setting is 4 seconds.
  • Compatible with any relay/contactor-based BMS, given the BMS allows the contactor to be installed on the positive terminal
  • Internal 3.15A fuse for contactor coil
  • Outputs 12vDC for TYCO Kilovac EV200ADANA or EV200AAANA Contactors


High input capacitance systems such as inverters, dc-dc converters, etc. can be exposed to large inrush currents during the initial power up procedure. If appropriate measures are not employed, these currents can overly stress or even damage the system components. The pre-charge unit eliminates high in-rush currents by charging the input capacitor before the main contactor switches on, prolonging lifespan of the contactor and other components dramatically.
