Product information

Description

The MEAN WELL SDR-120-12 120W Metallic is a compact industrial-grade DIN-rail power supply designed for stable 12 V DC output in control cabinets, automation systems and other electrical installations. It accepts a wide AC input range of 88–264 V, delivers a continuous 120 W with 150% short-term peak capability and reaches up to 91% efficiency. Constructed with a metal housing and intended for TS-35/7.5 or TS-35/15 DIN-rail mounting, the unit includes active PFC (power factor > 0.93), a built-in DC OK relay contact and meets recognised safety standards for industrial use.

Advantages

The SDR-120-12 offers high conversion efficiency (up to 91%) which reduces heat dissipation and lowers energy losses in continuous operation. Its 150% peak load capability and 100% full-load burn-in testing improve reliability under transient conditions. The built-in active power factor correction (PF > 0.93) ensures better mains compatibility and lower harmonic distortion. A metal enclosure and compliance with EN60950-1 and UL508 provide mechanical durability and safety certification for industrial environments.

Suitable for

  • Industrial control cabinets and PLC power supply
  • Automation and machine control systems
  • Security and access control equipment
  • Building management and HVAC controllers
  • Telecommunications and network devices requiring 12 V DC

  • Built-in DC OK relay contact
  • Full-load burn-in test: 100%
  • Safety standards: EN60950-1, UL508
  • Dimensions (W×D×H): 40 mm × 113.5 mm × 125.2 mm

How to use

Mount the SDR-120-12 on a standard TS-35 DIN rail and secure the unit according to installation instructions. Connect the AC supply within the 88–264 V range to the input terminals and verify correct polarity on the 12 V DC output before connecting loads. Observe the built-in DC OK relay to monitor output status and allow integration with supervisory systems. Ensure adequate ventilation around the metallic housing and follow local wiring regulations and grounding requirements during installation.

Usage recommendations

For reliable long-term operation, place the power supply in a ventilated enclosure free from excessive dust, vibration and heat sources. Consider the 150% peak capability when sizing backups or transient-heavy loads, and use proper wiring and overcurrent protection on both input and output circuits. Periodic inspection of connections and verification of the DC OK relay contact are recommended as part of preventive maintenance.
