ABB SAFT112POW Power Module: Technical Specifications (English Introduction)

The ABB SAFT112POW Power Module is a high-performance DC power supply unit designed for industrial automation, robotics, and machinery applications requiring reliable, high-efficiency power conversion. Below is a detailed technical overview:

1. Key Features & Applications

Purpose: Provides regulated DC power to ABB’s drive systems (e.g., ACS880, ACS580), PLCs, servo controllers, and other automation equipment.
Applications:
- Industrial Robotics (powering robot controllers and servo drives).
- Machine Tools (CNC, lathes, milling machines).
- Material Handling (conveyors, AGVs, cranes).
- Renewable Energy (wind turbine controllers, solar inverters).
Certifications:
- UL, cUL, CE, IEC 61010-1 (safety compliance for industrial use).
- EMC Compliance (EN 55011, EN 61000-6-2 for electromagnetic compatibility).

3. Advanced Functionalities

High Efficiency:
- Active PFC reduces harmonic distortion, improving energy efficiency and compliance with grid standards (e.g., EN 61000-3-2).
- 94% efficiency at full load minimizes heat generation and operating costs.
Protection Mechanisms:
- Overvoltage Protection (OVP): Shuts down if output exceeds 28.8 V DC.
- Overtemperature Protection (OTP): Fan speed increases or shuts down if internal temperature exceeds limits.
- Input Undervoltage Lockout (UVLO): Prevents operation during unstable input voltage.
Monitoring & Diagnostics:
- DC OK Signal: Relay contact indicates power status (normally closed/open).
- Remote Sense: Compensates for voltage ｄｒｏｐ in long cables.
- LED Indicators: Green (Power ON), Red (Fault).

4. Mechanical & Environmental Specifications

Enclosure: IP20 (NEMA 1) (standard), suitable for indoor installations.
Mounting: Wall-mounted or DIN rail-mounted (optional DIN rail adapter).
Vibration Resistance: 5–500 Hz, 2G (IEC 60068-2-6) (for harsh industrial environments).
Shock Resistance: 15G, 11 ms (IEC 60068-2-27).

5. Optional Accessories

Parallel Operation Kit: Allows multiple SAFT112POW units to share the load (for redundancy or higher current).
Remote On/Off Control: Enables external control of power module activation.
Output Voltage Trim Pot: Fine-tunes output voltage within ±10%.
