140CPS11420C Modicon Quantum Power Supply | 115/230 VAC Input 11 A Output

Schneider Electric 140CPS11420C: Power Your Quantum System

The Schneider Electric 140CPS11420C is the heart of your Modicon Quantum rack. It takes 115 or 230 VAC input and delivers clean, stable 5.1 VDC power at 11 Amps. Built for continuous industrial duty. No fans. No noise. Just reliable power.

Why This Power Supply Stands Out

• Dual-voltage input: 115 VAC or 230 VAC – auto-selecting, no jumper
• 11 Amp output capacity – powers full Quantum racks with spare margin
• Built-in relay contact (NC) for external alarm or interlock
• Low ripple and noise on 5.1 VDC bus
• 0 to 60°C full-load operation without derating
• Compact 40 mm width – saves panel space

• 2. Connect AC power to terminal block
• 3. Power up – green LED confirms DC OK
• 4. Wire relay contacts for alarm monitoring
• No software. No configuration. Instant power.

Real-World Applications

• Main power source for Modicon Quantum CPU and I/O racks
• Critical process control systems in oil, gas, water
• Factory assembly lines with 115/230V site power variance
• Redundant power configurations with dual supplies
• Legacy Quantum system upgrades and spare parts

Diagnostics & Status at Glance

• Front LED: Green = DC OK, Off = no output
• Relay: Normally closed, opens on power fail
• Connects directly to PLC input for remote failure alert
• No web server or software needed – pure hardware reliability

Frequently Asked Questions (Real Answers)

• Can 140CPS11420C run on 120 VAC?Yes. It accepts 100-132 VAC. No jumper change. Auto-senses input.
• What happens if output current exceeds 11 A?Unit shuts down. Reduce rack loading or add second supply.
• Is this module hot-swappable?No. Power down rack before removal. It supplies rack backplane power.
• Relay rated 6 A at 220 V. Can I switch motor directly?No. Use relay as signal to contactor. Direct motor load will weld contacts.
• My rack has 12 slots. Will 11 A be enough?Yes. Typical Quantum slot draws 0.5-1.2 A. 11 A covers full rack + margin.

Buying Guide & Field Tips

• Spare strategy:Store one 140CPS11420C per site. Power supply failure stops entire rack. Swap takes 3 minutes.
• Input voltage check:Module accepts both voltages. But verify site supply before wiring. 277 VAC will damage unit.
• Relay wiring:Use shielded pair for alarm signal. Avoid routing with AC power lines.
• Temperature placement:Install near bottom of cabinet. Cool air enters low. Heat rises. This extends capacitor life.
• Our recommendation:Order pre-tested units. We load-test at full 11 A for 2 hours. Ensures no infant failure.
