This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

TDK-Lambda 500W AC/DC Power Modules

TDK-Lambda’s PFH500F series of 500W high-efficiency quarter-brick power modules are ideal for industrial, test, communication, and commercial applications. 

The modules operate from a universal AC input and provide a 28V, 18A output, with the output voltage adjustable by ±20%. The PFH500F has remote on/off control, a Power Good output, and multiple protections. An optional PMBus interface can be used to program the output voltage, configure fault management functions, and monitor status.

The modules can also be used in droop mode current sharing to drive larger loads. The PFH500F series is suitable for conduction cooling and can operate in high ambient temperatures as the baseplate can withstand temperatures up to 100°C.

  • Input Voltage: 85VAC to 265VAC, 47Hz to 63Hz
  • Output: 28V / 18A
    • Adjustment range: 22.4V to 33.6V
    • Efficiency: up to 92%
  • Protections: OVP, UVP, OCP, OTP
  • Optional PMBus communication
  • Optional Droop Load Share (parallel operation)
  • Suitable for conduction cooling
    • -40°C to +100°C baseplate operation
