Overview
This product is designed for 12V automotive electronic equipments. 12V constant power behind the relay is a backup auxiliary power supply. The module does not need power supply after electronic devices in the vehicle are turned off.
Parameters
- Voltage: 12V
- Dimension：61.1mm × 19.9mm x 18mm
- Current: about 40ma during working; no current during standby
- Max. output current: 5A
- Default delay：30s
Operating mode
When there are ACC (12v) signals, the load (connection) works; when there are no ACC signals, relay will be switched on and it will be automatically turned off after a delay of power supply (ACC output terminals stops outputting voltage ) . And it prevents the devices from restarts.
Applications
Can be applied in cars for delay-off features after vehicle is shut down: after shutting down, automatic delay off of headlights (fog lights, high beams, reading lamps, etc.) and windows; delay-off functions for automotive navigation systems, car audio, reversing radar , radio , CD or DVD and MP3.
