140CPS22400C

Modicon Quantum – 5.1 VDC Backplane Power Supply

1. General Information

• Manufacturer: Schneider Electric

• Part Number: 140CPS22400C

• Series: Modicon Quantum PLC

• Type: Rack‑mount backplane power supply (redundant + summable)

• Input: 20–30 VDC (nominal 24 VDC)

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

• Application: High‑availability Quantum racks; N+1 redundant + parallelable up to 4 units = 32 A total

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

• Difference vs 140CPS22400: Same electrical specs, C = coated

• Difference vs 140CPS21400C: redundant + summable vs summable only

4. Key Features

1. 24 VDC wide‑range input: 20–30 VDC, industrial standard.

2. 8A high‑current 5.1 VDC output: for medium/large Quantum racks.

3. Redundant + summable: N+1 redundancy + parallel up to 4 units → 32 A.

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

5. NC alarm contact: remote fault monitoring (6 A / 220 VAC).

6. Hot‑swappable: replace without rack shutdown.

7. Full protection: OVP / OLP / SCP / thermal shutdown.

5. Certifications

• CE

• UL 508

• CUL / CSA C22.2 No 142

• FM Class 1 Div 2

• RoHS compliant

6. Ordering Notes

• 140CPS22400C: 24 VDC, 8 A redundant/summable, conformal coated, NC alarm.

• 140CPS22400: Non‑coated (standard version).

• Compare to 140CPS21400C: 22400C = redundant + summable; 21400C = summable only.

• Obsolete: Replaced by BMXCPS3500 (M340 platform).
