Overview
The document details the S8EX series of Switch Mode Power Supplies, including new 15-W and 30-W models, alongside existing 50-W, 100-W, and 150-W models. These power supplies cater to various applications with input voltages from 100 to 240 VAC and are available in configurations such as open models, models with chassis, and models with chassis and covers.

Specifications

Output voltages available: 5, 12, 24, and 48 V.
Compact design with consistent connectors.
Complies with EN 61000-3-2 for harmonic current.
Approved standards: UL 60950-1, cUR CSA C22.2 No. 60950-1, EN 50178, EN 60950-1.

Model Number Structure
Model numbers indicate power boost function, power factor improvement, power ratings, output voltage, configuration, and options like remote control and coating.

Ordering Information
Includes a detailed list of models with configurations, input voltage, power ratings, output voltage, output current, and model numbers.

Ratings, Characteristics, and Functions

Efficiency varies by model and input voltage.
Input voltage range: 85 to 264 VAC or 120 to 370 VDC, frequency: 50/60 Hz.
Features: overload protection, overvoltage protection, parallel operation capability, EMI and EMS compliance.
Environmental specs: operating temperatures from -10 to 70°C, storage temperatures from -25 to 75°C.

Additional Notes

Inverter outputs should be avoided due to temperature rise and ignition risk.
Output voltage adjustable by ±10% using V. ADJ feature.
Protection reset requires turning off input power for at least three minutes.

Output Specifications
Output voltage adjustable by ±10% using V. ADJ. Ripple voltage varies by output voltage, with a max of 960 mV for 48 V output. Input variation influence capped at 0.5%, load variation influence at 2% max, temperature variation influence at 0.05%/°C max.

Protection Features
Overload protection with automatic reset, overvoltage protection included. Parallel operation supported for up to two power supplies, series operation not recommended without external diodes.

Environmental Conditions
Operating temperature range: -10 to 70°C, storage temperature: -25 to 75°C, humidity: 25% to 85%.

Compliance and Standards
Complies with UL 60950-1, CSA C22.2 No. 60950-1, EN50178, EN60950-1, SEMI F47-0706, EMI and EMS standards including EN 55011 and EN61000 series.

Mechanical and Connection Details
Features input and output connectors, specific models and harnesses for different configurations. Weight varies by model, with the 150 W model weighing up to 315 g without chassis and cover.

Engineering Data
Derating curves provided for different mounting methods and power ratings, indicating load rate against ambient temperature. Overload protection reduces output voltage during short circuits or overcurrents.

Power Supply Usage and Limitations
Avoid applications with frequent inrush current or overloading. Overvoltage protection shuts off output if it exceeds 130% of rated voltage. Reset by turning off input power for at least three minutes.

Startup and Hold Time
Max startup time: 1,000 ms. Systems should consider startup time of other devices. Output hold time: minimum 20 ms.

Model Specifications
Models with and without power boost functions available, each with specific output voltage and current ratings. Dimensions and mounting hole specifications provided.

Safety Precautions
Do not disassemble, modify, or repair the product. Avoid touching the product while powered or immediately after power-off. Ensure no metal pieces enter during installation. Proper heat dissipation is crucial.

Wiring Guidelines
Ensure complete grounding and correct wiring of input and output terminals. Use appropriate wire diameters and materials to prevent overheating. Do not exceed current rating of output terminals.

Installation Environment
Avoid locations with shocks, vibrations, or strong noise sources. Store at temperatures between -25 to 75°C and humidity of 25% to 90%. Avoid direct sunlight and corrosive environments.

Output Voltage Adjustment
Output voltage adjustable to ±10% of rated voltage using V.ADJ on the front panel. Ensure output capacity does not exceed rated limits after adjustment.

Series and Parallel Operation
Series operation possible with precautions, parallel operation not recommended. Backup operation with external diodes possible.

Overload Protection
Avoid applications with frequent inrush current or overloading. Internal parts may deteriorate if overload conditions persist.

Power Boost Function
Boost current should not continue for more than 10 seconds, and duty cycle conditions must be met to prevent damage.

Additional mounting methods are also available. Ask your OMRON representative for details. Mounting method A Mounting method B (Standard mounting method) Use a metal sheet* for the mounting surface. Internal parts may occasionally deteriorate or be damaged. Do not use the Power Supply in areas outside the derating curve (i.e., the area shown by shading (T) in the above A natural convection system is used for derating. Mount the Power Supply so that air convection will occur around it. For 50,100, and 150-W models, check the derating characteristics for the input voltage before using the Power...
