Development of control panel for refrigeration dryer


Circuit board development technical parameters:


Structural features:


1. Wide application voltage range, voltage range from 180V to 260V can be used without transformer (380V can be customized).


2. Integrated remote control function, with remote switch machine and operation, fault monitoring (order option).


3. Start-up delay, start the compressor after 5~180 (adjustable) seconds after each startup, effectively preventing frequent startup.


4. With fault self-locking function, when the unit fails, it will be shut down and locked until manual recovery, effectively preventing the unit from running in a faulty state.


5. Using large-current small relays to isolate the output, the output current can reach 30 amperes, and the AC contactor or electric control box is omitted in the single-phase power supply unit, which effectively reduces the cost and energy consumption.


6. The use of micro-signal acquisition and control reduces the complexity of the circuit and improves the overall stability.


7. The operation interface is composed of one open and one stop two tact switches and five LEDs to indicate power supply indication, operation indication, high voltage fault, low voltage fault, and electrical fault. It is intuitive and easy to operate.


8. Strong versatility, the lamp position (hole position) is compatible with most refrigerated dryers on the market, such as: Jiuguangchang, Jiamei, Shengyuan, Xiangsheng, Ruipu, Ouzhuo, etc.
