The Edwards 3-EVPWRA is the assembled power-supply subassembly used with the EST3 3-ANNCPU1 graphic annunciator CPU. First, the assembly mounts to the 3-ANNCPU1 carrier. Then, supplied cable assembly 360136 lands on connector J5 of the 3-ANNCPU1. As a result, the annunciator CPU receives regulated power without site-built harnessing.
Specifically, the “A” suffix on the catalog number indicates “assembled” — the unit ships pre-built with mounting plate and cable. Therefore, installers skip the bench-assembly step required by the bare 3-EVPWR. In addition, the assembly is intended specifically for the 3-ANNCPU1 carrier rather than a generic chassis.
Edwards 3-EVPWRA install notes
Mount the 3-EVPWRA per the EST3 installation sheet (P/N 3100051). Furthermore, connect cable 360136 (supplied with the assembly) to J5 on the 3-ANNCPU1. Also, observe the polarity and pin orientation called out on the install sheet to avoid CPU damage.
Verified facts
- Catalog number: 3-EVPWRA (assembled variant of 3-EVPWR)
- Application: power supply for the EST3 3-ANNCPU1 annunciator CPU
- Cable: assembly 360136 (supplied) terminating at J5 on the 3-ANNCPU1
- Documentation: EST3 Installation Sheets P/N 3100051
- Listing scope: covered by EST3 system listings (no standalone UL listing at the subassembly level)
For annunciator service replacements, the 3-EVPWRA is the faster swap because it arrives pre-assembled. However, the bare 3-EVPWR board is functionally equivalent if mounting and cabling are built on site. As a result, choose the variant that matches the carrier hardware already in place.
