System Architecture & Signal Flow
The S82G-1024 employs a forward converter topology with active power factor correction (PFC) on the AC input stage, ensuring compliance with EN 61000-3-2 harmonic current limits. The regulated 24VDC output is derived through a high-frequency transformer (switching frequency ~100 kHz), followed by synchronous rectification and LC output filtering to achieve the specified ≤150 mVp-p ripple.
Typical Panel Wiring Architecture:
- AC Input → Circuit Breaker (6A MCB) → S82G-1024 AC Terminals (L / N / PE)
- S82G-1024 DC Output (+24V / 0V) → 24VDC Bus Bar → PLC CPU / I/O Modules / Field Devices
- DC OK Relay Contact → PLC Digital Input (DI) for power health monitoring
- Parallel units connected via Schottky diode OR-ing module for redundancy
Ground the PE terminal directly to the panel chassis. Maintain minimum 25 mm clearance above and below the unit for convection airflow. Derate output current linearly from 10A at 50°C to 6A at 60°C.

Technical FAQ
Q: Can the S82G-1024 replace an S82G-1024D or S82G-1024J?
A: The base S82G-1024 is the standard 24VDC/10A model. Suffix variants (D, J) may indicate regional certifications or connector options — confirm the exact suffix requirement with your panel documentation before ordering.
Q: Is parallel operation supported without additional hardware?
A: Parallel operation requires external Schottky diode OR-ing (e.g., OMRON S82V-ORG) to prevent reverse current flow between units. Direct parallel connection without OR-ing is not recommended.
Q: What is the derating curve above 50°C?
A: Output current must be linearly derated from 10A at 50°C to 6A at 60°C. Operation above 60°C is not permitted.
Q: Does the S82G-1024 support 48VDC output?
A: No. The S82G-1024 is fixed at 24VDC output (adjustable ±10%, i.e., 21.6–26.4 VDC). For 48VDC requirements, refer to the OMRON S8FS-C or S8VK-G series.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit for standard orders. Volume pricing available for orders of 5 units or more.
