Blue Sea Systems - ML-Series Heavy Duty Automatic Charging Relay

An Innovative Solution for Control and Safety

Introducing our advanced manual control switch, designed to revolutionize your power management system. With its cutting-edge features and exceptional performance, this switch offers unparalleled control and safety for a wide range of applications. Two variants of this remarkable product are available:

7622 - A Reliable 12V Powerhouse

The 7622 model is equipped with a 12V coil voltage, ensuring efficient power management in various setups. Its standout feature is the manual control switch, which provides an added level of safety. This switch allows you to control your system with or without power, offering a unique "Locked Off" capability for convenient servicing.

Additionally, the 7622 includes the ML-Series Remote Control Contura Switch PN 2146, further enhancing the ease of use and functionality. With a continuous rating of 500 Amps, this device delivers outstanding performance for demanding applications.

The Magnetic Latch (ML)-ACR technology in this model draws very low current, less than 10 mA, to monitor terminal voltage in both the "ON" and "OFF" states. It also draws moderate current for a very short time when changing state, ensuring efficient power usage.

The 7622 offers versatile configuration options, including Start Isolation (SI) and Engine Isolation (EI). These features enable temporary isolation of house loads from the engine circuit during engine cranking, protecting sensitive electronics and maximizing alternator output. The switch senses charging on two battery banks, providing valuable information about your power system.

Designed to accommodate high-output alternators up to 500 Amps, the 7622 ensures optimal performance even in demanding situations. The LED output allows you to remotely monitor battery status, indicating when batteries are combined, isolated, in voltage lockout, or in Start or Engine isolation modes.

Featuring 3/8"-16 tin-plated copper studs, this switch ensures maximum conductivity and corrosion resistance. The 7/8" (22mm) stud length readily accepts multiple cable terminals, providing flexibility in your installation. The switch also incorporates label recesses for circuit protection and utilizes silver alloy contacts for high reliability in switching live loads.

7623 - Unmatched Performance with 24V Capability

For those seeking a higher coil voltage, the 7623 model offers exceptional performance with its 24V capability. This variant includes all the outstanding features of the 7622 model while accommodating the specific power requirements of 24V systems.

Like its counterpart, the 7623 switch boasts the manual control switch, ML-Series Remote Control Contura Switch PN 2146, and a 500 Ampere continuous rating. The Magnetic Latch (ML)-ACR technology ensures efficient power management, with low current draw in the "ON" or "OFF" states and a short burst of moderate current during state transitions.

The Start Isolation (SI) and Engine Isolation (EI) features enable temporary isolation of house loads from the engine circuit, protecting sensitive electronics and optimizing alternator output. Charging monitoring on two battery banks provides valuable information for efficient power management.

Supporting high-output alternators up to 500 Amps, the 7623 model is ready to meet the demands of your power system. The LED output feature allows you to remotely monitor battery status, ensuring you stay informed about the power flow.

With the same superior construction and design as the 7622 model, the 7623 switch features 3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance. Its
