Victron Energy BCD Diode Battery Combiners ensure continuous DC power to mission-critical equipment by allowing two or more DC power sources to be used in parallel; failure of one source will not interrupt power to the critical load. The combiners use Schottky diodes to achieve a low voltage drop (approximately 0.3 V at low current and approximately 0.45 V at rated output). Typical applications include mission-critical systems such as electronic engine control systems. Warning: hot surface—mount the Diode Battery Combiner on a non-flammable surface only.
