4731 AC/DC Power Adapter with Universal Inputs

Overview

The 4731 is a power adapter manufactured by Mean Well that takes universal inputs (90 to 264 Vac, 47 to 63 Hz) and outputs 24 Vdc at 1.5 A. It float charges the sealed rechargeable batteries of the ET107 weather station via ac power. It can also be used with some retired weather stations such as the ET106, W2000, NW8000 series, and 010 series. The 4731 is included in the 10522 ac-power kit for ET stations.
