Automatický nabíjecí relé série m - 12/24 V DC 65 A

The Blue Sea m-Series 7601 automatic charging relay (ACR) is designed to automatically manage dual-battery bank systems. It combines batteries during charging for efficient power distribution and isolates them during discharge or shutdown, protecting the starter battery and optimizing energy availability.

This automatic charge relay has a continuous current capacity of 65 amperes. Its intermittent current capacity is 115 amperes, maintained for 5 minutes.

Yes, the Blue Sea m-Series 7601 automatic charge relay is designed to work with 12V DC or 24V DC electrical systems.

Main functions include automatic battery bank combination during charging, battery isolation during discharge, dual charge detection on either battery bank, and a start-up isolation (SI) function to protect sensitive electronic equipment.

The relay includes a soft-start isolation function (SI) that protects sensitive electronic equipment from voltage drops and spikes that can occur when the engine starts.

Compared to traditional diode-based battery isolators, the m-Series 7601 charge relay offers higher efficiency. It generates less heat and consumes minimal charging power.

Yes, this relay is flame-resistant and compliant with external ignition protection requirements per ISO 8846 and SAE J1171, making it safe for installation on gasoline-powered boats.

The Blue Sea m-Series 7601 automatic charge relay is rated IP67, ensuring protection against temporary immersion up to 1 meter for 30 minutes.

To prevent corrosion of wires and connection terminals, it is recommended to mount the relay in a dry and protected location if possible. Avoid locations directly above battery banks.

The recommended tightening torque for terminal studs is 60 in-lbs (6.8 Nm).

For a continuous load capacity of 65 amperes, it is recommended to use a minimum cable size of 6 AWG (16mm²) and a fuse of 90A-100A. The maximum supported cable size is 1/0 AWG (50mm²).

The starter isolation line (SI) must be connected to the terminal or wire running from the ignition switch to the starter solenoid. This connection must be positive only during starting and must be made via an inline fuse of one to ten amps.

No, the m-Series 7601 charge relay is not designed to handle starting currents. If batteries need to be combined for emergency starting, a battery switching system with a combining/parallel function must be used.

Connect the positive terminal of one battery bank to one of the 1/4"-20 studs, and the positive terminal of the other battery bank to the other 1/4"-20 stud. Both positive connections must be made through appropriately sized circuit protection (fuse).

The quick-connect terminal marked GND (ground) must be connected to the DC system ground via a 1 A inline fuse. This prevents fault currents in this wire.

This automatic charge relay can support alternators up to 65 amperes.

For a 12V system, the relay will combine the batteries if the voltage at either terminal is above 13.6V DC for 30 seconds or above 13.0V DC for 2 minutes.

For a 24V system, the batteries are isolated when the voltage at either terminal drops below 25.5V DC for 30 seconds or below 24.7V DC for 10 seconds.

Yes, the relay includes undervoltage protection (lockout at 9.5V DC for 12V systems and 19V DC for 24V systems) and overvoltage protection (lockout at 16.0V DC for 12V systems).
