Selection Guide

This power supply supports AC input and can be directly connected to the mains supply.The previous two models (45-0043-B00 and 45-0056-D00-R1.02) are DC-input secondary voltage conversion modules. These modules require an external DC power source at the front end to provide the required input voltage.
