DIN Rail DC-DC Converter Ideally Suited for Flexible, Compact, and High-Reliability Applications


Single, Flexible and Configurable “All-in-One” Unit Covers Multiple Applications

Santa Clara, CA - Bel Power Solutions and Protection introduces the LDD240-WU, a revolutionary DIN Rail DC-DC converter ideally suited to applications where flexibility, compactness and high reliability are required.  It is fully isolated and highly efficient over a broad operating range of input and output voltages. In addition, its compact size and ease of installation make it ideal for most industrial applications, such as control panels, instrumentation, machine building and railway, and  can complement or even replace existing models and families of DC-DC converters.

The LDD240-WU is a 240 W, 4.2 kV isolated DC-DC converter that can convert any DC voltage between 11 to 55 V to any DC voltage between 5 and 55 V, with 10mV resolution, using Digital Power regulation to give up to 240 W output (max 10 A). Existing converters are based on a fixed input and output voltage, which generates many individual models (for example: 24 Vin, 48 Vin, 5 Vout, 12 Vout and 24 Vout) that need to be individually qualified and stocked. With Bel Power’s new LDD240, only one model needs to be qualified and stocked, resulting in a significant cost savings.

The output voltage setup can be done through the front panel, or through a Modbus over a USB interface (using either Windows or Android) for remote monitoring and control. Integrated ORing circuitry allow the units to be paralleled for power or redundancy. Multiple self-protection mechanisms and user-settable constant current or hiccup mode limitation is also a key feature.  

The LDD240-WU is currently in stock with Digi-Key. For more detailed information, visit belfuse.com/power-solutions.
