Warm-Up Board

WECO 9050

The WECO 9050 Warm-Up Board from Radian Research provides a safe, easy-to-use solution for AMI meter functional testing — allowing shops to validate meter power-up, displays, AMI communications, firmware version, disconnect switch operation, and error status clearance quickly and efficiently. By handling these basic functional checks on a dedicated warm-up board, shops avoid tying up accuracy Test Boards with meters that haven’t yet passed basic operational validation, keeping throughput moving and test assets focused on accuracy work.

Built with the highest quality meter socket design Radian Research is known for, the WECO 9050 is available in single or double-sided configurations with up to 56 meter capacity. Each vertical bank of four sockets is independently isolated with its own power switch and resettable circuit breaker, and selectable ANSI meter form and voltage switches give each column the flexibility to accommodate a wide range of meter types without reconfiguration of the board itself. Note: the WECO 9050 does not include an Energy Reference Standard or current source.

Product Highlights

Safety is central to the WECO 9050’s design. Each socket is equipped with a dead front safety interlock mechanism, and the addition of a plexiglass socket shield guides meter blades into the zero insertion force jaws while minimizing the risk of inadvertently dropping meter seals onto socket conductors. Manual lever jaw release and all-aluminum frame construction round out a platform built for years of reliable shop use.

The WECO 9050’s selectable ANSI meter form switch covers 1S, 2S, 3S, 4S, 5S/35S/45S, 6S/14S, 9S/16S, and 12S/25S forms, while the voltage selection switch accommodates 69V through 600V across ten settings — making the board compatible with the broadest possible range of residential and commercial AMI meters without requiring socket bypass adapters.

Features

The WECO 9050 Warm-Up Board delivers safe AMI meter functional testing for up to 56 meters with selectable ANSI form and voltage switches and zero insertion force sockets.
  • Zero Insertion Force meter sockets — highest quality socket design guides meter blades into jaws without requiring force, reducing wear and blade damage risk.
  • Dead front safety interlocks and socket shield — plexiglass shield guides meter blades during insertion and prevents seals from contacting socket conductors.
  • Up to 56 meter capacity — available in single or double-sided configurations to match shop throughput requirements.
  • Selectable ANSI meter form switch — covers 1S, 2S, 3S, 4S, 5S/35S/45S, 6S/14S, 9S/16S, and 12S/25S forms; no socket bypass adapters required.
  • Selectable voltage switch — ten voltage settings from 69V to 600V: 69V, 120V, 138V, 208V, 120/240V, 240V, 277V, 347V, 240/480V, 480V, and 600V.
  • Isolated column breakers — each vertical bank of four sockets has its own power switch and separate resettable safety breaker for independent column control and fault isolation.
  • All-aluminum frame with locking wheels — durable all-aluminum construction with roll-around locking wheels for safe shop floor mobility.
