TDK-Lambda has added a 1000W brick-sized power supply in its PFE range of AC-DC supplies.

Called the PFE1000F, it combines the AC to HVDC front-end with DC-DC converter into a single module with a baseplate-cooled design.

Up to six PFE1000F units can be operated in parallel, achieving outputs of up to 5.1kW. For use in high reliability equipment, N+1 redundant parallel operation is possible.

In a 100x13.4x160mm package, models are available in 12, 28 and 48V nominal outputs and can be adjusted +/-20%. The 12V versions deliver 720W with a maximum baseplate temperature of 100°C, while the 28V and 48V models provide 1008W.

A wide-range AC input allows operation from any voltage between 85V and 265V at 47 to 63Hz. As standard, they incorporate active power factor correction and input-to-output isolation of 3000VAC for one minute. Over voltage, over current and over temperature protections are also included.

The PFE1000F Series also has additional features such as remote on/off control, inverter operation good (IOG) signal and an auxiliary power supply for external signals (nominal 12V/20mA).

The modules have circuitry to improve lightning surge withstand capability up to 6kV when installed using recommended reference design.
