A rectifier converts an alternating current (AC) to a direct current (DC).
The RU-3424 is a single phase rectifier that converts 100V/110V/115V/220V/230V AC applied to its input terminals to 24V direct current voltage and 20 Amperes direct current.
Rectifier Unit RU-3424 needs to be installed in a dry, place that is well-ventilated. This is to protect it from moisture and the ventilation is to allow for cooling. Since a wide and varying range of input voltage can be supplied to this rectifier, there is a provision for altering the internal connection of the rectifier using jumper wires accordingly depending on input voltage supplied at its input terminals.
