High power density rectifiers exceed 90% efficiency for enhanced DPA front end

Ultimate Renaissance (UR) has added a new range of high efficiency front-end modules to its solutions for distributed power architectures (DPAs). The modules are up to 91% efficient, raising the performance of any DPA. Further features include a wide AC input range, high power density design allowing 1200W and 1500W power levels in a 1U format and 2700W in 2U, and field replaceable front mounted fans for easy maintenance.

UR's TDI Mercury power modules deliver military grade features, plus HALT and HASS test certification, in commercial cabinet and telco form factors at commercial cost. 1200W, 1500W and 2700W modules are

available, with custom front cover colours if required.   The 1200W and 1500W modules deliver standard output voltages of 12V, 24V, 27V, 48V and 56V, from 90-275VAC input for the 1200W model, or 176-275VAC input for the 1500W model. The 2700W model has input voltage range 185-275VAC, and available outputs 24V, 27V, 48V and 56V. All models may be specified with custom output voltages.

The modules can be easily paralleled, and UR can supply turnkey full-shelf systems built on the Mercury platform, for power requirements up to 10.8kW. Available solutions include 1U/3kW and 2U/10.8kW shelves, with further options including the 4.8kW single shelf Pico system with built-in monitoring and status reporting, RS 232 interface and integral micro-based controller. UR also offers TDI power systems up to 42kW, combining Mercury modules with backup batteries and power controller. These are available in standard cabinet or rail mount configurations.
