Information about the MEAN WELL WDR-240-48

The MEAN WELL WDR-240-48 is a robust industrial DIN rail power supply engineered to thrive in challenging electrical environments by supporting a wide single and two-phase input range of 180 to 550V AC. This versatility makes it an indispensable component for high-voltage industrial grids, effectively eliminating the need for a neutral wire in many two-phase applications. Designed with a built-in active PFC circuit, the unit maintains an impressive 91% efficiency rating, which significantly reduces internal heat generation and ensures long-term stability. Its slim 63mm metal chassis is optimized for space-constrained control cabinets, utilizing fanless natural convection cooling to maintain peak performance without the noise or maintenance concerns associated with mechanical fans.

Delivering a precise 48V DC output at 5A, this power supply is specifically tailored for sensitive industrial electronics, telecommunications equipment, and high-voltage motor controls. It features an integrated DC OK relay contact for simplified system monitoring and a voltage adjustment range of 48V to 55V to account for potential line drops in complex installations. The WDR-240-48 is built to withstand rigorous conditions, meeting heavy industry immunity levels (EN61000-6-2) and carrying UL 508 approval for industrial control equipment. With comprehensive protection against overloads, short circuits, and thermal runaway, it provides a highly secure and durable power solution for automation professionals seeking mission-critical reliability in a compact form factor.
