The board is small in size and stable in operation. It adopts 2mm double-sided printing board. The control relay adopts Songle 30A high-power relay, full copper wire quality control transformer, original NE555 time base IC chip, copper foot metal film resistor, and imported capacitor.
The ON-OFF control terminates the power switch of the power amplifier without any changes to the original panel.
Basic parameters:
Control power: 50W-1000W Maximum 1500W (above 1000W, please add solder to the solder mask on the back side of the printed board.
Standby power consumption: 2W
Delay start: 3-5 seconds (press the switch, relay No. 1 is turned on, power is supplied to the transformer through the thermistor, the thermistor will heat up after loading, and increase the resistance value, thus offsetting the impact of large current, 3 After 5 seconds, the relay No. 2 is turned on. At this time, the thermistor stops working, and the relay is directly energized by the relay.
Board size: 92 X 70 X 40 mm
Indicator light: plug in the listing power plug for standby mode, the red LED will also light up (this light can be connected to the machine panel for power indication, you can also use the common cathode two-color LED) 3-5 seconds after pressing the power switch The green indicator light is on, and the road has been turned on for normal operation.
