Modicon Quantum Power Supply, 120/230V AC, 5.1VDC 3A, Conformal Coated

General Information

  • Manufacturer: Schneider Electric

  • Model: 140CPS11100C

  • Series: Modicon Quantum PLC

  • Type: Standalone AC Power Supply Module

  • Status: Discontinued / Obsolete

  • Function: Provides 5.1 VDC logic power to Quantum backplanes and I/O; “C” = Conformal Coated (for harsh environments)

Description

140CPS11100C is the conformal‑coated version of 140CPS11100, a compact, standalone AC power supply for Modicon Quantum PLC systems. It converts 120/230 V AC into 5.1 VDC / 3 A to power the PLC backplane, CPU, and I/O modules. The conformal coating protects against dust, moisture, and corrosive gases (e.g., salt, H₂S), making it suitable for industrial, coastal, or high‑humidity environments.

  • Input Current: 400 mA @ 115 V; 200 mA @ 230 V

  • Inrush Current: 20 A @ 115 V; 10 A @ 230 V

  • Output Voltage: 5.1 V DC

  • Output Current: 3 A (continuous)

  • Rated Power: 50 VA

  • Operating Temp: 0 °C to +60 °C

  • Protection: Internal overvoltage, overload, short‑circuit

  • Fuse: 1.5 A slow‑blow

  • LED: 1 × green “PWR OK”

  • Weight: ~0.65–0.66 kg

  • Certifications: CE, UL 508, CUL, CSA C22.2, FM Class 1 Div 2

  • Coating: Conformal coated (140CPS11100C only)

Key Features

  1. Conformal Coating (“C”): Enhanced protection for harsh, humid, or corrosive environments

  2. Wide AC Input: 100–276 V AC, global compatibility

  3. Compact & Standalone: Mounts directly to Quantum backplane; no external DC needed

  4. High Efficiency: Low harmonic distortion (≤10%)

  5. Built‑in Protection: Overvoltage, overload, short‑circuit safeguarding

  6. Discontinued: Replaced by newer Quantum power supplies

Applications

  • Modicon Quantum PLC systems (CPU, backplane, I/O power)

  • Harsh environments: chemical, water/wastewater, coastal, mining

  • High‑humidity, dusty, or corrosive industrial sites

  • Hot standby kits: 140CHS41010 / 41020 (standard power supply)

Differences

  • 140CPS11100: Standard (non‑coated), 5.1 VDC 3 A, 120/230 V AC

  • 140CPS11100C: Conformal coated version (harsh environment)

  • 140CPS21100: Higher power (8 A), wider temp range, non‑coated

  • 140CPS21100C: 8 A + conformal coated
