This control board with the dimensions length = 162.5mm / width = 70mm / height = 35mm serves as current controller for the portable charger B3200. The control allows stepless adjustment of the charging current from 6A to 36A with a manually operated potentiometer (picture 2) and in parallel with external control voltage from 0V to 10V DC. This feature is interesting for photovoltaic system owners. The PCB can also be operated directly with charging currents of up to 16 amperes in one phase (figure 3), however, an additional relay must then be soldered to the slot provided for this purpose (please specify this application case when ordering). In the case of three phase operation and charging currents up to 36 amps (figure 5), a contactor must be used (please contact us for specific recommendations). The series resistors for the two supplied LEDs are on the control board. Scale examples in figures 4 and 6 or in scale 1:1 under Downloads.
