The TDK-Lambda PH50S280-28 is an isolated DC-DC converter module from the PH-S series. It provides a single regulated output of 28V at up to 1.8A, delivering 50W of power. The converter accepts a wide input voltage range of 200V to 400V DC, making it suitable for high-voltage bus applications in industrial and commercial equipment.
Key electrical specifications include line regulation of 0.4% or 20mV and load regulation of 0.8% or 40mV. Ripple and noise are limited to 280mV pk-pk. The module includes protection features such as overcurrent (105-140% with auto recovery), overvoltage (125-145%), and overtemperature protection with internal sensing and self-resetting. Remote on/off control is provided (active low).
The converter is housed in a through-hole module package measuring 86.0mm x 41.0mm x 12.7mm. It is designed for conduction or forced air cooling. The operating baseplate temperature range is -20°C to +85°C. Safety certifications include UL60950-1, CSA60950-1, EN60950-1, and CE Mark. The product is RoHS3 compliant and has an MSL of 1 (unlimited).
