1200W full brick 200-425V input DC-DC modules aresuitable for high voltage distributed power systems
November 30, 2022
TDK Corporation (TSE:6762) announces the introduction of the TDK-Lambda brand PH1200A280 full brick DCDC converters. Rated at 1200W with an input of 200 to 425Vdc, the modules deliver isolated, regulated 12V, 24V,
28V, 36V and 48V outputs. The converters are very suitable for 380Vdc input distributed power systems using
non-isolated AC-DC power supplies. Other applications include semiconductor fabrication, communicationsystems, test and measurement and custom power supplies utilizing a power module-based solution.
The PH1200A280 is packaged in the industry standard full brick footprint, measuring 116.8mm in length, 61mm
wide and 12.7mm high (4.6 x 2.4 x 0.5 inches) enabling low profile designs. The modules can operate reliably inambient temperatures from -40 oC to 85oC and baseplate temperatures from -40 oC up to 100oC. With efficienciesof up to 94% less internal waste heat is generated, simplifying cooling using either an optional heatsink orconduction into a cold plate.
Standard features include remote sense, remote on/off, inverter good signal and a 10 to 14V auxiliary voltage. Upto 11 modules may be connected in parallel with current sharing to provide additional power and an internal
ORing FET is provided for redundant operation. The PH1200A280 has wide range output adjustment of -40% to+20% from nominal using the trim terminal for non-standard voltages.
The input and output isolation is 3,000Vac, input to baseplate 2,500Vac and the output to ground is 500Vac.
Safety certification is to the IEC/EN/CSA/UL 62368-1 standard and has CE / UKCA markings to the Low Voltage
and RoHS Directives. With external circuitry the PH1200A280 will meet radiated and conducted emissions andcomply with the IEC 61000-4 immunity standards.
