Description

Power Performance:

Input Voltage: 100–240 VAC (50/60 Hz) or 110–300 VDC, with wide-range tolerance (±15%) to handle grid fluctuations.
Output Voltage: 24 VDC ±2% (adjustable), with rated current up to 10 A (total for both channels) to support multiple I/O modules.
Efficiency: ≥85% at full load, reducing energy loss and heat generation.

Redundancy & Reliability:

Dual Channels: Two independent power paths with automatic load sharing; if one channel fails, the other assumes full load without interruption.
Protection Mechanisms: Overcurrent (12 A trip), overvoltage (28 VDC cutoff), short-circuit, and overtemperature (70°C shutdown) protection.
Diagnostics: Real-time status monitoring via LEDs (power on, channel active, fault) and digital output signals (for integration with DCS alarms).

Integration & Compatibility:

Mounting: Designed for S800 I/O racks (e.g., CR301, CR310) and ABB controller enclosures, with front-panel installation for easy access.
Hot-Swappable: Supports module replacement without powering down the system, minimizing maintenance downtime.
System Compatibility: Works with ABB S800 I/O modules (e.g., PFXA401F), Profibus interfaces (PFVO143), and AC800M controllers.
