AC 12V 10A Dual Channel Speaker Horn Protection Board Finished Transparent Relay with LED
Description:
- Dual channel horn protection board. Finished plate.
- Adopt a fully discrete transistor element., a set of independent detection of DC signal for two channels respectively.
- Different from the UPC1237 IC two channel that shared a set of detection. Avoid two channels at the same time will be asymmetric DC
- On board, two sets of 10A large current, silver contact relay.
- AC 12 V power supply. With voltage regulator, maximum voltage is AC 18V.
- Note: protection board supply power, can not share the same set of voltage with the former,Will be short-circuit damage.
- Input DC voltage > + - 0.6V, then cut off IN OUT.
- On board with LED display, boot delay, or under DC protection, LED will be flashing state.
- Normal work, LED is a long light state.
Testing on protective board:
- With a digital universal table, pull to position 2 pole .
- Red pen connect to IN, black pen to GND, relay, LED flashing.
- Then use black pen to IN, red pen to GND, relay is cut off, LED flashing, then it is normal.
