REC Master

The Master can support either High voltage series strings of SI-Q Series BMS strings up to 600V or High Current strings up to 7500 Ah at 62V by networking up to 15 Slave 16S BMS's.

 The REC BMS Master supports many battery chemistries including: Li-PO, LiFePO4, LiFeYPO4, LiCoO2, LiMnNiCo and LiMnO4 Lithium-Ion chemistry Master + max 15 Slave combination (max 240 cells) compatible with all REC BMS units single cell voltage measurement (0.1 – 5.0 V, resolution 1 mV) single cell internal resistance measurement single cell under/over voltage protection SOC and SOH calculation over temperature protection (up to 3 temperature sensors per Slave unit) under temperature charging protection passive cell balancing up to 1.3 A per cell with LED indication shunt current measurement (resolution 10 mA @ +/- 300 A) 3 galvanically isolated user defined multi-purpose inputs/outputs 4 programmable relays (normally open and normally closed option) 12 V galvanically isolated supply (Select your voltage) galvanically isolated RS-485 and CAN communication protocol error LED + buzzer indicator internal battery powered real time-clock (RTC) PC user interface for changing the settings and data-logging (optional accessory) LCD touch display for monitoring (optional accessory) hibernate switch
