140CPS51100C

Modicon Quantum – 5.1 VDC Backplane Power Supply

1. General Information

• Manufacturer: Schneider Electric

• Part Number: 140CPS51100C

• Series: Modicon Quantum PLC

• Type: Rack‑mount backplane power supply (standalone / summable)

• Input: 100–150 VDC (nominal 125 VDC)

• Output: 5.1 VDC (logic power for Quantum backplane)

• Application: Quantum racks with 125 VDC plant supply; small/medium racks; parallel summable (2 units max → 6 A)

• Coating: Conformal coated (Humiseal 1A33) – harsh environment version

• Difference vs 140CPS51100: Same electrical specs, C = coated

• Key Trait: No redundancy, no alarm contact (basic 125V coated supply)

4. Key Features

1. 100–150 VDC wide‑range input: for 125V DC industrial systems。

2. 3A compact 5.1 VDC output: for small/medium Quantum racks。

3. Summable (2 units max): parallel up to 6 A total。

4. Conformal coated: dust, moisture, chemical resistance (harsh environments)。

5. Basic protection: OVP/OLP/SCP/thermal shutdown。

6. Green “PWR OK” LED: local status only (no alarm relay)。

7. Hot‑swappable: replace without rack shutdown。

5. Certifications

• CE

• UL 508

• CUL / CSA C22.2 No 142

• FM Class 1 Div 2

• RoHS compliant

6. Ordering Notes

• 140CPS51100C: 100–150 VDC, 3 A standalone/summable, conformal coated, no alarm contact。

• Compare to 140CPS51100: 51100C = coated; 51100 = non‑coated。

• Compare to 140CPS2xxx/4xxx: 51100C = 125V input; 2xxx=24V; 4xxx=48V。
