PH300S280-3.3 Description

Short technical summary and product information.

The PH300S280-3.3 is a high-density DC-DC converter from TDK-Lambda's PH-S Series. It delivers 300W of output power at 3.3V from a wide input voltage range of 200V to 400V DC. This module is designed for commercial ITE applications and offers a compact through-hole package measuring 86.0mm x 41.0mm x 12.7mm.

 

Key electrical specifications include line regulation of 0.4% or 20mV and load regulation of 0.8% or 40mV. Ripple and noise is limited to 100mV pk-pk. The converter provides comprehensive protection features including overvoltage protection (150-180%), overload protection (105-140%), and thermal protection with internal sensing and self-resetting.

 

The PH300S280-3.3 includes remote on/off (active low), remote sensing, and an inverter good signal. It offers high isolation of 3000VAC input to output and 2500VAC input to baseplate. The module can be cooled via conduction or forced air, with an operating baseplate temperature range of -20°C to +85°C.

 

Safety certifications include UL60950-1, CSA60950-1, EN60950-1, and CE Mark. The converter is backed by a 2-year warranty.
