PANALARM (AMETEK) 90P18X6D1C4D Series‑90 Annunciator Power Supply Module
The PANALARM 90P18X6D1C4D is a 450‑watt regulated power supply unit for the Panalarm Series‑90 alarm annunciator system. It accepts 125VDC input and delivers stable regulated 24VDC output to power alarm window modules, annunciator logic boards and alarm horn devices, providing steady power source for plant alarm annunciation in power‑plant, petrochemical and refinery control‑room systems.
This enclosed NEMA‑1 rated power supply adopts forced‑air fan cooling, built‑in over‑voltage, over‑current and short‑circuit protection circuits, and provides status LED indicators for power‑supply health monitoring. It is housed within metal enclosure with wiring terminal box, widely used as aftermarket spare part for annunciator cabinet overhaul, power‑loop debugging and plant safety‑alarm‑system retrofitting projects.
