UPC1237 Speaker Amplifier Protection Board Dual Relay Board Kit for Japan

Descrizione di UPC1237 Speaker Amplifier Protection Board Dual Relay Board Kit for Japan

uPC1237 serves as the core component, equipped with functions such as power- delay, protection, and anti-shock during power failure
Use fully sealed high-current relays as core components to prevent contact sparking and oxidation. Double parallel connection allows each channel to be independent, doubling the current while reducing internal resistance by half, beneficial for lossless sound transmission
Use 7812 for voltage stabilization, with a wide power supply range, capable of reaching any range from AC12V to AC24V
The circuit is simple and reliable. It is very easy to manufacture and requires no debugging
Description
Please pay attention to the installation of UPC1237; the letters should face outward. If installed backwards, there will be no delay; normal delay is 3 seconds

The board uses double-sided immersion gold double-sided panels with low internal resistance

High sensitivity and low contact resistance can ensure the use of dual-channel amplifiers to 200WX2 (2-8) ohms. It can also be used in parallel with contacts 400W amplifiers
