TDK Lambda Announces Improved Efficiency 1000 Watt AC-DC Baseplate Cooled Modules
TDK Corporation introduces the TDK-Lambda PFE1000FA series of AC-DC power modules, a
significant upgrade to the popular PFE1000F series launched eight years ago. The new series
achieves up to a 4% efficiency improvement (up to 90%). Like the existing models, the
innovative PFE series enables designers to utilize a single device containing power factor
correction, regulation and input-output isolation. These modules have been widely used in
outdoor and liquid cooled power systems, addressing the need for fan-less applications in the
industrial, COTS, signage and communications markets.
Operating from a universal input of 85-265Vac, the PFE1000FA models are available with
nominal outputs of 12, 28 and 48Vdc and can be adjusted +/-20% via a trim-pin. All the power
modules can deliver full power with an operating baseplate temperature range of -40 to +100oC
(+85oC for the 28V and 48V models below 170Vac). An isolated module good signal, remote
on/off, 12V standby output, over voltage, over current and over temperature protection is
included on all models.
The package size and pin-out is in the same 100 x 13.4 x 160mm format as the original series,
allowing an easy upgrade of existing designs for up to 30% lower power losses and reduced
temperatures. An enhancement to the PFC circuit gives a more sinusoidal input current wave
form, providing lower harmonic currents as defined by the IEC 61000-3-2 standard. The
warranty has been extended to 5 years.
The TDK-Lambda PFE1000FA series is certified to the safety standards of UL/CSA/EN 60950-1
and is CE marked according to the Low Voltage and RoHS2 Directives.
