Information about the MEAN WELL TDR-240-48

The MEAN WELL TDR-240-48 is a high-performance three-phase industrial DIN rail power supply designed to provide 240W of reliable 48V power in a slim 63mm width body. This compact form factor is specifically engineered to maximize cabinet space while maintaining high power delivery. A standout feature of this series is its wide-range input capability, supporting 340 to 550 V AC across three phases, and even allowing for dual-phase operation or high-voltage DC input up to 780 V DC. With an efficiency of 92%, the unit operates with minimal thermal loss, allowing for a fanless design that relies on free air convection for cooling across a wide ambient temperature range of -30 °C to +70 °C.

For enhanced operational monitoring and safety, the TDR-240-48 includes a built-in passive PFC function to meet EU harmonic current regulations and a DC OK relay contact for real-time status feedback. The integrated constant current limiting circuit for overload protection makes this power supply exceptionally well-suited for inductive or capacitive applications, such as those found in semiconductor fabrication and industrial automation. Furthermore, its compliance with UL61010 and Overvoltage Category III (OVC III) standards ensures the device can withstand significant voltage transients, making it a robust and competitive choice for mission-critical industrial control systems.
