Product Brief:

1661D89G03 is Emerson Ovation MMI dedicated power supply module, wide‑range universal AC input variant iterated from 1661D89G01 and 1661D89G02. It supports 85‑264V wide‑range AC input, converts AC power into multi‑channel stable DC power to supply Ovation man‑machine interface operator station and related display components. It integrates complete protection functions including over‑voltage, over‑current, short‑circuit and over‑temperature protection, effectively avoids damage to MMI hardware caused by power‑supply abnormality. It supports power‑fault signal feedback for system status monitoring. LED indicators show power‑on and fault conditions for convenient on‑site inspection. This is EOL discontinued spare part,widely used for maintenance and renovation of thermal power plant Ovation DCS system. Please confirm MMI hardware configuration and input power condition before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement.
