DC/DC converter offers internal redundancy

The rugged mechanical construction has no internal wiring, which increases its vibration-withstand capacity. Internal printed circuits are conformal coated for protection from moisture. Natural convection cooling provides sufficient cooling for operation over a 0 to +50°C temperature range without de-rating. Wider temperature ranges are available on request.

The BHR 65X2-4U2NF converter operates from DC-inputs of 48VDC or 125VDC and deliver a single output of 24, 48 or 125VDC. A ± dual output configuration is also possible. Typical conversion efficiency is 85% at full load. Two 500W internal modules are connected redundant parallel, which provides inherent redundancy: the failure of one internal module would result in a 50% drop in output power while the unit remains functional at 500W. The converter can also be used as a 500W redundant power supply.

The BHR 65X2-4U2NF is designed for compliance with EN/UL60950-1 and equivalent safety standards. It is well suited to a broad range of heavy-duty industrial applications where fan cooling is not permitted, and where replacement or repair of electrical equipment is not practicable. An EN50155-compliant railway quality version is also available.
