140CPS42400C

Modicon Quantum – 5.1 VDC Backplane Power Supply

1. General Information

• Manufacturer: Schneider Electric

• Part Number: 140CPS42400C

• Series: Modicon Quantum PLC

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

• Input: 48–60 VDC (nominal 48 VDC)

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

• Application: Critical Quantum racks with 48V DC plant supply; supports 1+1 redundancy and parallel summing (up to 4 units → 32 A)

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

• Difference vs 140CPS42400: Same electrical specs, C = coated

• Difference vs 140CPS41400C: 42400C = redundant + summable; 41400C = summable only

2. Electrical Specifications

Input (DC)

4. Key Features

1. 48–60 VDC wide‑range input: for 48V industrial systems。

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

3. Redundant + Summable: 1+1 redundancy (fault‑tolerant) + parallel up to 4 units → 32 A total。

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

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

6. Green “PWR OK” LED: local status。

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

8. Hot‑swappable: replace without rack shutdown。

5. Certifications

6. Ordering Notes

• 140CPS42400C: 48–60 VDC, 8 A redundant + summable, conformal coated, NC alarm。

• 140CPS42400: Non‑coated (standard version)。

• Compare to 140CPS41400C: 42400C = redundant + summable; 41400C = summable only。

• Compare to 140CPS22400C: 42400C = 48V input; 22400C = 24V input。
