2. This board uses a large current (100A) pure copper foot relay and a large thermistor NTC 20D-20, effective protection of the machine, to prevent excessive start-up current
3. This board does not need auxiliary power, only 2 terminals, one connected to the power input (before connecting a switch control), an output connected to the load, very convenient to use
4. Market sales with amplifier soft start with high-voltage capacitors are omitted the discharge resistor, which leads to soft start circuit board in the unplugged power supply is still charged extremely unsafe, resulting in plug charged easy to hurt the family, the board is with a safe discharge resistor can be used with confidence
5. The product is not suitable for 40W 100W 200W 300W and other small power equipment soft start, belongs to the high current soft start, power on instantly give about 300-400W soft start current, about 3 seconds relay suction on
Note: This product is not suitable for motor class use
Name: high-power power soft start circuit board
Relay: RGL high-power super current 100A pure copper foot relay
Scope of application: suitable for high-end audio power input, or other large start-up current machine applications
Power: suitable for use within 2400W, long-term load is best within 1400W!
Power supply voltage adaptation range: AC150V-280V
Initially connected to the power supply, through the two negative temperature coefficient of the thermistor to the load power supply, as the thermistor temperature rises, the resistance value decreases, the voltage rises slowly, thus effectively suppressing the impact of inrush current on the line and the impact on other appliances. About 2 seconds later the relay will be closed, short-circuiting the thermistor, the power will be supplied directly to the load through the relay contacts, and the load will enter normal operation.
Wiring sequence: power supply - switch - soft start - transformer
1 x High Frequency Filter Module
