GE IC695PSD040 – PACSystems RX3i DC‑DC Power Supply Module (40W, 24VDC Input)

In stock

Product Introduction: The IC695PSD040 is a compact, high‑reliability DC‑DC power supply for the Emerson PACSystems RX3i PLC platform, designed for 24VDC nominal input systems. It converts a wide 12–30VDC input into three regulated outputs (+3.3VDC, +5.1VDC, +24VDC) to power the RX3i backplane, CPU, and I/O modules. Engineered for industrial DC power environments (e.g., battery‑backed systems, solar installations, 24VDC plant grids), it offers robust protection, high efficiency, and a streamlined form factor for space‑constrained control panels.

Key Features

Wide DC Input Range: Operates reliably from 12–30VDC (run mode), compatible with 24VDC plant power, battery banks, and renewable energy systems.
Triple Regulated Outputs: Dedicated outputs for logic (+3.3VDC), backplane (+5.1VDC), and relays/sensors (+24VDC) ensure stable power distribution.
High Efficiency: ≥85% efficiency minimizes energy waste and heat generation, critical for sealed or low‑ventilation control panels.
Robust Protection: Overload, overvoltage, short‑circuit, overtemperature, and reverse polarity protection safeguard the module and connected devices.
LED Status Indicators: Front‑panel LEDs for Power, P/S Fault, Overload, and Overtemperature enable real‑time diagnostics and quick troubleshooting.
Compact 1‑Slot Design: Occupies a single RX3i slot, optimizing space in control panels with limited rack real estate.
Rugged Industrial Design: Withstands vibration, shock, and wide temperature ranges for reliable operation in industrial DC power environments.
