Often installed friends all know, the internal chassis board too much means a lot of connection lines need to be processed, the connection is the most time-consuming thing, if not handled properly it will affect the appearance of the wiring layout, weight may be due to unreasonable wiring loop or interference noise. So, our new design of soft start and rectifying and filtering integrated plate perfectly solves the above problems, the board of large power soft start, rectifying and filtering in a body, and also supports large reservoirs or multi capacitance capacitor in parallel installation. With this board, it will greatly shorten the time machine and ensure clean and complete installation, the board used 2mm thick fiberboard, 70UM copper thickness and in the high current go online for tin processing, ensure the high current smoothly.

softThe starting circuit by high power relay, high power thermistor, low power standby power supply and control part, the board is set to two 220V output, can connect two independent transformers in addition, the board is additionally provided with a temperature protection circuit, with the board with 75 temperature switch two, a radiating fin can be two temperature or power the switch are respectively arranged on the left and right tube surface, when the temperature reached 75 degrees will automatically cut off the power, in order to avoid high temperature burn power tube, such as the need to change the shutdown temperature, temperature switch to buy other temperature normally open type value. In addition, when the protection line action, you may have to wait for a period of time, the actual temperature is lower than the temperature switch start temperature, you can open the machine again.

After loading the capacitor:
