Charge Mate Pro 40 - Electronics Charge Relay

Current limited electronic charge relay with high efficiency and reverse current protection

A secondary battery on board requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example.

In automatic charging mode the Charge Mate Pro limits current to the second bank, prioritizes the primary battery and blocks reverse current even when the secondary bank has a higher voltage. An optional remote switch supports emergency starting by overriding automatic operation. In ON mode the banks are connected in parallel and bidirectionally; PULSE connects them for 30 seconds. This differs from the current-limited automatic charging mode and disables the current limit.

A marine application example is the connection of a bow thruster battery to a service battery. The Charge Mate Pro ensures that the service battery is always charged with priority. The blocking of the return current from the bow thruster battery guarantees that the bow battery remains charged while the current limiting also prevents power dips of the onboard electrical network.

The Charge Mate Pro series consists of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications.

Charge Mate Pro: for controlled charging from a single source.

Applications

• Leisure and professional marine and mobile applications. An effective solution for high power demand on board and/or the need for prioritized or current limited charging.

Features

• Electronic charge coupling with very low voltage drop
• Makes effective dual charging possible
• Suitable for compatible battery types; lithium-ion installations require the specified Multipurpose Contact protection (product code 77030500).
• Automatic-mode charge current to the secondary battery is limited to 40 A.
• High system reliability by prioritized charging of the main battery
• Automatic charging mode blocks reverse current. Remote ON/emergency-start operation overrides automatic operation and can connect the banks bidirectionally.
• Prevents power dips of the onboard electrical network
• Use with compatible chargers or alternators within the selected model’s voltage, current and battery requirements.
• Monitoring with LED status indication
• IP65 electronics in a corrosion-resistant casing with aluminum heat sinks
• Fast and easy installation

Installation and operating modes

Use the selected 40 A model only in a 12 V or 24 V system with a common negative and battery banks with matching charge characteristics. Default automatic mode limits current to 40 A; the optional remote switch changes that operating mode as described in the manual.

Turn off electrical power and disconnect battery loads before installation. Install in the positive lead between banks, provide the specified negative connection, keep cables short and free of loops, and route positive/negative cables close together. Mount in a ventilated location with vertical fins, never directly above batteries. Follow the selected-model manual’s wiring, protection and local safety requirements; inspect connections at least annually.
