The KHHD004A2B41-SRZ is an isolated DC-DC converter module from ABB Power Electronics, part of the Hammerhead series. It delivers a regulated 12V output at 4.2A (50W) from an ultra-wide input voltage range of 18V to 75Vdc. The module achieves 90% efficiency at full load (48V input) and features a constant switching frequency.
This converter is designed for use in wireless networks, hybrid power architectures, optical and access network equipment, enterprise networks with Power over Ethernet (PoE), and industrial applications. It includes protections such as overcurrent, overvoltage, overtemperature, and under-voltage lockout. The output voltage can be adjusted from 80% to 110% of nominal.
The module is surface-mount in an 8-SMD package with dimensions of 33.0mm x 22.9mm x 9.3mm (1.30 x 0.90 x 0.37 inches). It operates over a temperature range of -40°C to 85°C. The part is RoHS3 compliant and carries UL, CSA, IEC, EN, and CE safety approvals.
