PH300A 300 W DC-DC Converter Series

TDK Corporation announces the introduction of 300 W models to the TDK-Lambda's PH-A280 series of DC-DC power modules with high voltage DC input. Operating from a wide range DC input of 200 VDC to 425 VDC, which is widely used in high voltage DC current (HVDC) applications, the PH-A280 range now includes 50 W, 75 W, 100 W, 150 W, and 300 W outputs.

The PH300A280 power modules are available in four output voltages: 12 V, 24 V, 28 V, and 48 V. These outputs are adjustable over a very wide range of -60% to +20% to suit non-standard voltages. Efficiencies of up to 92% are achieved, an improvement of 5% over the prior PH series.

All modules operate at full load over a baseplate temperature range of -40°C to +100°C making them suitable for liquid, air cooled, or conduction cooled systems. The dimensions follow the industry standard half brick format (61.0 mm x 12.7 mm x 57.9 mm).

As standard, the PH-A280 units are equipped with remote sense, remote on/off, overvoltage and overcurrent protection circuitry, and include a 5-year warranty. All models have an input-to-output isolation of 3 kVAC, are safety-approved to UL/CSA/EN 60950-1, and carry the CE mark in accordance with the LV Directive.

Features
  • Industry standard ½ brick format
  • High efficiency of up to 92%
  • 200 VDC to 425 VDC input
  • Output voltages of 12 V, 24 V, 28 V, and 48 V
  • Five-year warranty
