Automatinis įkrovos jungiklis m serijos – 12/24 V DC 65 A

The Blue Sea m-Series 7601 automatic charge 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 when stopped, protecting the starter battery and optimizing energy availability.

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

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

Main functions include automatic battery combining 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 integrates a Start Isolation (SI) function that protects sensitive electronic equipment from voltage drops and spikes that can occur during engine start.

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

Yes, this relay is flame-resistant and meets the external ignition protection requirements of 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, providing protection against temporary immersion up to 1 meter for 30 minutes.

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

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

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

The start 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 charging relay can support alternators up to 65 amperes.

In 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.

In a 24V system, 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).
