Product description

The Victron BCD 402 – 2 Batteries 40A (Combiner Diode) is a high-quality diode battery coupler that ensures an uninterrupted power supply in DC systems. The use of high-performance diodes allows two separate batteries or power sources to be connected in parallel without any reverse currents between the sources. This ensures that the connected consumer is supplied at all times – even if one energy source fails.

This principle is particularly suitable for safety-related systems such as motor controls, emergency power supplies, or communication systems where power failure must be avoided at all costs. The BCD 402 ensures stable power distribution at a maximum current of 40 amps and is suitable for 12 V and 24 V systems.

Thanks to its compact design, robust construction, and high efficiency, the diode coupler is a reliable component for use in maritime, industrial, or mobile energy applications.

Typical applications

Parallel connection of two battery systems
Secure power supply in the event of a power source failure
Marine and vehicle installations
