IMO SPS-1-015-12DC 15W DIN-Rail Power Supply, 12V DC, 1.25A
Space-saving Class 2 DIN-rail power supply with universal AC/DC input, adjustable 12V DC output, 1.25A capacity, and integrated fault protection.
Why Choose the IMO SPS-1-015-12DC Power Supply?
The IMO Precision Controls SPS-1-015-12DC converts 85–264V AC or 120–370V DC input to 12V DC at up to 1.25A. With 15W of output in a housing only 0.7 inch wide, it fits compact machine-control panels that power 12V relays, sensors, interface devices, indicators, and other low-power automation components.
This Class 2 supply combines 88% efficiency with Class II isolation and free-air convection cooling. Overload, overvoltage, and hiccup-mode short-circuit protection help isolate faults, while the 10.8–13.8V DC trim range supports controlled output adjustment for the installed circuit.
🔋 12V DC Output
Supplies up to 1.25A and 15W for 12V control and automation loads
📏 Slim DIN Profile
0.7-inch-wide housing makes efficient use of limited rail space
📈 88% Efficiency
Reduces conversion loss in compact enclosed control panels
🛡️ Fault Protection
Provides overload, overvoltage, and short-circuit protection
⚠️ Confirm 12V DC Load Requirements
Verify the required voltage and polarity for each device before connection. Combined steady-state and startup demand must remain within the 1.25A and 15W output ratings, with any required environmental derating or design reserve applied.
📋 Selecting Capacity for 12V DC Controls
Total the nameplate current of every 12V DC relay, sensor, controller, indicator, and interface device on the branch. A 0.9A continuous load leaves 0.35A below this supply’s 1.25A maximum before application-specific reserve or derating is considered.

📋 12V DC Panel Integration Overview
1. Identify Every Load: Confirm which panel devices require 12V DC and record their normal and startup current.
2. Check Available Capacity: Keep total demand within 1.25A and 15W after applying the design reserve required by the application.
3. Verify the Source: Confirm that incoming power is within the listed universal AC or DC input range.
4. Install on DIN Rail: Provide suitable clearances for wiring and free-air convection cooling.
5. Commission the Circuit: Check polarity and output voltage before energizing connected controls.
Installation and commissioning should be completed by qualified personnel in accordance with the product instructions, panel design requirements, and applicable electrical codes.
🏭 Recommended 12V DC Uses
• 12V DC relay and interface circuits
• Industrial sensors and indicators
• Compact controllers and process instruments
• Small automation panels that need a narrow Class 2 supply
