Description
The TDK-Lambda DRB240-24-3-A0 is a high-performance DIN rail-mounted 3-phase power supply delivering 240W output at 24VDC / 10A. Designed for reliability in demanding industrial environments, this model is ideal for applications such as control systems, machine automation, and industrial enclosures where space, efficiency, and performance are critical.
Operating from a wide 3-phase input range (350–575VAC), the DRB240-24-3-A0 supports global deployments and ensures stable power delivery with minimal heat loss thanks to its high efficiency of up to 92.7%. The adjustable output voltage (22.5–28.5VDC) and boost mode output of up to 288W for 600 seconds make it suitable for starting high inrush loads and maintaining voltage stability under load variations.
Equipped with screw-type terminals, the supply includes DC-OK relay contacts and a remote inhibit input for enhanced control and system integration. Built-in protections such as constant current overload mode, overvoltage shutdown, and thermal derating safeguard both the load and the power supply itself.
With compact dimensions (65mm wide), convection cooling, and compliance with key international standards including CE, UKCA, UL, and IEC/EN 61010-1, the DRB240-24-3-A0 is engineered for long-term reliability in mission-critical DC systems.
