Overview of the two-channel speaker protection board:
Overview of the two-channel speaker protection board:
1. UPC1237 speaker protection chip dual-channel protection design,
2. Direct 220V AC power supply, built-in sealed small transformer on the board.
3. Use high-current terminal blocks for easy wiring.
4. Each channel uses a relay independently, the mono channel control current is 30A, suitable for power amplifier output protection below 2000W
5. When the designed LED lights up, it means it works normally.
performance:
Power-on delay: about 3S (3 seconds)
Midpoint protection: about 1V
Working voltage: AC 220V
Board size: length 85mm, width 66mm, height 26MM, net weight: 158g
Protection category: startup protection, shutdown protection, DC midpoint protection
Remarks:
1). The relay adopts 30A sealed relay, one channel is controlled by one relay, and each channel is controlled by 30A current. The compact design of the small board saves installation and use space.
2). AC 220V power supply requires professional operation, high voltage is dangerous! ! ! !
Special attention is paid to the UPC1237 speaker protection circuit which is only suitable for ordinary power amplifier boards shared by the ground wire, and is not suitable for BTL, balanced output power amplifiers, or power amplifier circuits with capacitor output such as 1969.
