The BA PS3000A-FW is a 3 A power supply that accepts 24 VAC input and delivers a regulated 1.2 VDC to 24 VDC output with full‑wave rectification, part of BAPI's PS3000 voltage‑converter family. It uses 16–22 AWG wiring for connections and is designed for installation in commercial control panels powering BAPI ETA interface devices and other low‑voltage building‑automation modules. Note: the PS3000A-FW is documented as a “without backplate” model; the backplate‑equipped variant is the PS3000B-FW, which shares the same output and full‑wave operation for integrated mounting on backplates.
