vector-VID DC Power Supply WP-775B power supply Repair Service

Professional diagnostic and board-level repair service for this vector-VID DC Power Supply WP-775B power supply.

The WP‑775B is a 30 VDC/5 A regulated power supply with selectable 110 / 220 VAC input (SW3). Common failure points in this model are the primary filter capacitors and the output voltage regulator IC; overheating or a blown fuse often causes loss of regulation. First‑check steps: verify mains voltage and that the internal fuse is intact, then measure the output voltage with a load to confirm regulation; finally inspect for bulging electrolytics or burnt components on the main board.
