Schneider Electric 140CPS52400C Modicon Quantum – 5.1 VDC Backplane Power Supply (8 A Redundant / Summable, 100–150 VDC Input, Conformal Coated, No Alarm Contact) 1. General Information Manufacturer: Schneider Electric Part Number: 140CPS52400C Series: Modicon Quantum PLC Type: Rack‑mount backplane power supply (redundant / 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; large/heavy‑load racks; 1+1 redundancy; parallel up to 16 A Coating: Conformal coated (Humiseal 1A33) – harsh environment version Difference vs 140CPS52400: Same electrical specs, C = coated Key Trait: Redundancy capable (1+1), no alarm contact 2. Electrical Specifications Input (DC) Voltage: 100–150 VDC (nominal 125 VDC) Input Current: 0.5 A @ 125 VDC Inrush Current: 28 A max @ 125 VDC Hold‑up Time: ≤ 1 ms @ 125 VDC External Fuse: 2 A time‑lag (slow‑blow) Output Voltage: 5.1 VDC ±1% (regulated) Current (@60°C): 0.5–8 A continuous (redundant / summable) Redundancy: Supported (1+1 mode) Total Parallel Current: Up to 16 A (2 × 8 A modules, summable only) Ripple & Noise: < 50 mVpp typical Protection: OVP / OLP / SCP / thermal shutdown (all internal) Power Dissipation: 6 + (1.5 × Iout) W (Iout in A) Efficiency: ≥ 85% typical Signaling & Alarm Local Indication: Green “PWR OK” LED Alarm Contact: None (no relay output) 3. Environmental & Mechanical Operating Temperature: 0 °C to +60 °C Storage Temperature: −40 °C to +85 °C Relative Humidity: 95% RH max, non‑condensing Altitude: Up to 5,000 m Protection Class: IP20 (indoor use) Mounting: 1 slot in Quantum backplane; hot‑swappable Dimensions: 103.9 × 40.3 × 250 mm Weight: Approx. 0.65 kg Conformal Coating: Yes (Humiseal 1A33) – C suffix 4. Key Features 100–150 VDC wide‑range input: for 125V DC industrial systems。 8A high‑current 5.1 VDC output: for large/heavy‑load Quantum racks。 Redundant (1+1): two units for fault‑tolerant operation。 Summable (2 units max): parallel up to 16 A total。 Conformal coated: dust, moisture, chemical resistance (harsh environments)。 Basic protection: OVP/OLP/SCP/thermal shutdown。 Green “PWR OK” LED: local status only (no alarm relay)。 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 140CPS52400C: 100–150 VDC, 8 A redundant/summable, conformal coated, no alarm contact。 Compare to 140CPS52400: 52400C = coated; 52400 = non‑coated。 Compare to 140CPS51100/51100C: 52400C = 8A redundant; 51100C = 3A non‑redundant。 Compare to 140CPS2xxx/4xxx: 52400C = 125V input; 2xxx=24V; 4xxx=48V。
