Charging and discharging resistor

Product introduction:
Charging and discharging resistor is used to discharge the electric energy after the capacitor is charged, and is usually in parallel with the capacitor. In case of power-supply fluctuation, the capacitor will be charged and discharged. If no charging and discharging resistor is set, the discharge current will flow from one end of the capacitor to the other end through the working circuit, seriously disturbing the stable operation of the circuit and possibly damaging ancillary equipment such as capacitors. If charging and discharging resistor is provided, the charge and discharge current will flow through the resistor to avoid the above problems. The resistor operation can be switched through intelligent control technology, so the resistor can work more accurately, reasonably and stably in the discharging process.

The discharging resistor for supercapacitor in rail transit system can flexibly adjust the discharging time through the switch. It is small in size and free of maintenance. Starting resistor can generally be metal or ceramic resistor; in particular, ceramic resistor is featured by small size and strong resistance to large current impact.
