TDK-Lambda PFH05W Evaluation Boards are designed to evaluate the PFH500F 500W High-Efficiency AC-DC Power Modules. Two types of evaluation boards are available: one type is populated with the PFH500F module configured for droop mode current share, and the other is without the droop mode current share. When AC power is applied, the board has high voltage present and may take time to decay after AC power is removed. External forced air cooling may be needed.
