GYS 12V/140A αυτόματος διαχωριστής μπαταρίας (082564)

The GYS 082564 stands apart from simple relay-based isolators by combining a 140A continuous rating with automatic voltage-sensing control in a sealed IP65 housing. It connects or disconnects a secondary battery based on the alternator voltage, eliminating manual switches or ignition wiring in dual-battery setups.

Highlights

• 140A continuous current rating, 160A peak for 5 seconds
• Automatic cut-in at 13.3V and cut-out at 12.8V
• Overvoltage, undervoltage, reverse polarity, and short circuit protection
• IP65-rated ABS housing with M6 stud terminals and status LED
• Low standby consumption under 10mA

In daily use

When the engine runs and the alternator raises the main battery above 13.3V, the coupler engages and charges the auxiliary battery. When the engine stops and voltage drops below 12.8V, it disconnects, preserving the starting battery. The surface-mount design suits RVs, boats, 4x4s, and commercial vehicles.
