Product Details
The Victron Energy BCD 402 2 Batteries 40A (Combiner Diode), is a reliable solution designed to ensure continuous DC power to mission-critical equipment by combining two DC power sources. This diode battery combiner allows two batteries to supply power in parallel, ensuring that failure of one source will not interrupt power to the critical load.
It is suitable for both 12V and 24V systems and features M6 bolt connections for secure and efficient installations. The device boasts a maximum continuous current of 40A, making it ideal for various applications.

Standards & Compliance
- Safety: EN 60950, CSA/UL 62368-1
- Emission: EN 61000-6-3, EN 55014-1
- Immunity: EN 61000-6-2, EN 61000-6-1, EN 55014-2

Installation Requirements
- Mounting: Must be installed on a well-ventilated vertical surface close to (but not directly above) the batteries.
- Wiring: Use at least 0.75 mm² wire for negative, positive, and midpoint connections. For UL compliance, fuse wires near the batteries with a 10A DC-rated fuse.
- Scalability: For 48V systems, three balancers are used. Several balancers can be connected in parallel to manage large battery banks (typically one balancer per three parallel 200 Ah strings).
