Keetec AUTORELAY 12V
AUTORELAY 12V is a practical automatic relay for controlled charging of a second battery in a vehicle, primarily intended to power dashcams, recording devices and other auxiliary electronics. It helps effectively separate the starter and auxiliary battery so devices can be safely powered even when the vehicle is parked, without unnecessarily draining the main battery needed to start the engine. It is an appropriate solution for users who want to use camera parking modes or operate other devices while keeping the assurance of reliably starting the vehicle.
A major advantage of this relay is the automatic switching on and off based on battery voltage. The relay engages at 13.3 V and disconnects when the voltage falls below 12.8 V, so charging of the auxiliary battery occurs only at the appropriate time. The device also monitors the voltage of both batteries, offers overvoltage protection and operates without voltage drop, contributing to efficient and safe operation of the entire installation.
AUTORELAY 12V is suitable for charging currents up to 140 A and uses a 3-wire battery connection with M6 terminals. A practical addition is an indicator LED for status monitoring. The relay consumes 16 mA when open and 320 mA when closed, and the product dimensions are 67 × 67 × 53 mm. Thanks to this, it represents a compact and functional solution for installations where reliable charging of a second battery while driving is required.
