RAC03-GA/GB & RAC04-GA/GB AC-DC Converters

RECOM Power RAC03-GA/GB and RAC04-GA/GB AC-DC Converters are designed to supply smart building infrastructures continuously and efficiently. The 3W and 4W converters feature high efficiency and no-load power consumption of 75mW for energy-saving solutions. Standard 3.3, 5, 12, 15, and 24V_DC outputs are suitable for power relays, gateways, and building automation nodes. The RECOM RAC03-GA/GB & RAC04-GA/GB converters feature a universal input voltage range from 85V_AC to 305V_AC for worldwide use. These converters are EN55022 Class A (RAC-GA) or Class B (RAC-GB) certified without additional components. The RAC03-G and RAC04-G series are ideal for IoT and smart home applications.
