• Status Indicators: Power OK, Fault, DC‑OK LEDs on front edge

• Redundancy: Supports parallel redundant operation with load sharing

Core Functions

• Dual‑Node Isolated Power: Delivers independent, noise‑isolated power to two nodes

• Wide‑Range AC Input: Adapts to global industrial voltage standards

• High Efficiency: Low heat dissipation for long‑term reliability

• Fault Tolerance: Auto‑shutdown on faults; alarm signaling to host system

• Hot‑Swap Ready: Can be replaced in redundant systems without downtime

Application Scope

• Honeywell TDC3000 / Experion PKS DCS control nodes and I/O subsystems

• Process industries: chemical, power, oil & gas, refining, pharmaceuticals

• Compact DCS cabinets where 5/10‑slot file supplies are oversized

• Redundant control systems requiring dual‑node power isolation

Operation & Maintenance Instructions

• Install with system powered off; follow ESD protection procedures

• Confirm AC input voltage is within 85–265 VAC range before power‑on

• Verify Power OK/DC‑OK LEDs are on; Fault LED off in normal operation

• Periodically clean ventilation slots and connectors; ensure unobstructed airflow

• Store spares in dry, ESD‑protected environment; avoid extreme temperatures
