Charge Mate 2502 — Automātisks bateriju slēdzis

The Mastervolt Charge Mate 2502 is an automatic battery relay designed to optimize the management of two battery banks in marine installations and recreational vehicles. It automatically connects both batteries during charging phases so they charge simultaneously, then isolates them the rest of the time to prevent the main battery from being drained by auxiliary equipment. It can also be used for emergency starts via an optional remote switch.

The Charge Mate 2502 has compact dimensions of 90 mm (height) x 80 mm (width) x 85 mm (depth).

The weight of the Charge Mate 2502 is 0.65 kg.

The Charge Mate 2502’s electrical consumption is very low, under 1 mA when the relay is open (solenoid not activated), whether on 12 V or 24 V DC.

The Charge Mate 2502 can handle a maximum continuous current of 500 A.

The Charge Mate 2502 is robust and can support a starting current (over 250 ms) of up to 2000 A.

The Charge Mate 2502 offers several operating modes to suit your needs:

On: Batteries remain connected in parallel.Off: The relay stays open, batteries are isolated.Auto: The relay automatically connects and disconnects batteries based on voltage.Start Assist: Allows temporary parallel connection of batteries for emergency start.

Yes, the Charge Mate 2502 is universally compatible with 12 V and 24 V systems. It automatically detects the nominal voltage of the installation (12 V or 24 V).

The Charge Mate 2502 is compatible only with 12 VDC or 24 VDC installations with a common negative ground.

The Charge Mate 2502 should be installed as close as possible to the batteries and the charging source (charger/alternator). However, it must never be installed directly above the batteries due to possible corrosive fumes. It must be installed on the positive cable between the two battery banks.

During installation, it is imperative to take the following precautions:

Ensure the power source is disconnected and remove all electrical connections to the charger/alternator and batteries.Check that no loads are connected to the batteries to avoid dangerous situations.Use cables with the appropriate cross-section and keep connections as short as possible.Use reliable terminals and tighten connection nuts firmly, but do not overtighten.

Yes, you can use an optional single-pole ON-OFF-ON switch to remotely control the Charge Mate. Here’s how it works:

If the switch contact is connected to the negative pole, the relay remains open (Off mode).In the center position (OFF), the Charge Mate operates in automatic mode.A brief contact with the positive pole (ON) will connect the batteries for 30 seconds for emergency starting (Start Assist mode).Continuous contact with the positive pole (ON) will keep both house batteries connected in parallel (On mode).

The recommended cable cross-sections for the Charge Mate 2502 depend on the DC current:

For 75 – 100 Amp DC: 25 mm² (AWG 3)For 100 – 140 Amp DC: 35 mm² (AWG 1-2)For 140 – 200 Amp DC: 50 mm² (AWG 0)It is critical to use cables with the appropriate cross-section and to keep connections as short as possible to optimize performance and safety.

Yes, an optional external status LED (with a maximum current of 120mA) can be connected to the 'STATUS' contact of the Charge Mate 2502 for remote indication.
