140CPS41400

Modicon Quantum – 5.1 VDC Backplane Power Supply

1. General Information

• Manufacturer: Schneider Electric

• Part Number: 140CPS41400

• Series: Modicon Quantum PLC

• Type: Rack‑mount backplane power supply (summable only, non‑redundant)

• Input: 48–60 VDC (nominal 48 VDC)

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

• Application: Quantum racks with 48V DC plant supply; parallelable (up to 4 units → 32 A total)

• Coating: Non‑coated (standard)

• Key Difference vs 140CPS21400: 48V input (21400 = 24V)

• Key Difference vs 140CPS42400: 41400 = summable only; 42400 = redundant + summable
