Hardware Manual
BMS Master 4 / 4.5
Ref.: IR14417 A 15.01.2018 Page 52/76
Peak consumption while communicating with MASTER ~ 20 mA
Stand-by/sleep-mode with MASTER inactive ≤ 0.03 mA
Balancing current per cell without external resistors (voltage dependent) 70 ... 90 mA
3.5.9. ENVIRONMENTALS
Humidity: max 95%, non-condensing
Working temperature: -20°C ... +70°C
Storage temperature: -40°C ... +70°C
At pollution level 2 the Slave may be operated at voltages up to 650 VDC
At pollution level 3 the Slave must not be operated
In applications with voltage differences > 650 VDC non-conducting screws (e.g. Nylon)
have to use for fixing the molded module.
Maximum insulation voltage must not exceed 1000 VDC.
Environmental testing:
Temperature Test acc. ISO16750-4:
o 24 h at –40 °C
o 96 h at +85 °C
o 4 x Cycles at -40°C and +85°C
Insulationtest: 300GΩ / 5kV DC.
EMC: according EN 55022 and EN 55024 (industrial)
