Product Description
Eaton MTL 8910-PS-DC | 12V DC System Power Supply Module
Regulated 12V DC Power for Process Control & Industrial Automation Systems
1. Product Overview

The Eaton MTL 8910-PS-DC is a high-reliability regulated DC system power supply module, engineered to deliver stable 12V DC power to critical control equipment in industrial automation and process control systems. As a modular power solution from MTL (now part of Eaton Corporation), it accepts a wide 18.5–36V DC input (compatible with standard 24V DC industrial supplies) and provides a precise 12V DC ±5% output with up to 4.9A current capacity, ensuring consistent power delivery to sensors, transmitters, and low-voltage control components. Designed for harsh industrial environments, it operates from -40°C to +70°C (with load-dependent derating), features input-output isolation (50V AC rms / 720V DC continuous per EN61010‑1), and supports redundant parallel operation for uninterrupted system uptime during single-module failure. Equipped with over-voltage, over-current, and short-circuit protection, plus LED status indicators for power, fault, and redundancy, it serves as a robust power backbone for mission-critical applications requiring continuous and reliable power.

4. Installation & Maintenance
Installation: Mount on standard DIN rail; connect 18.5–36V DC input (24V DC nominal); wire 12V DC output to load circuits; set redundancy jumpers if using parallel operation; verify isolation and proper grounding; check LED indicators for normal status.
Maintenance: Inspect input/output terminals for tightness and corrosion; monitor LED fault indicators for early issue detection; clean module vents to prevent dust buildup; replace faulty modules promptly to maintain redundancy; test hold-up time and protection functions annually.

Fault Diagnosis: Use LED status to identify power loss, over-current, or redundancy failure; measure input voltage for under/over-range conditions; check output for regulation errors; verify load current does not exceed 4.9A rating; inspect isolation integrity with a multimeter.
