This document introduces the functions and classifications of switching power supplies, with a focus on the characteristics and selection methods of switching power supplies. Switching power supplies have advantages such as small size, light weight, and high efficiency, but they also have disadvantages such as generating noise and having a large primary side transient current. When selecting a switching power supply, factors such as input voltage, input current, and efficiency need to be considered.
This manual describes the purpose, advantages, and basic operation of Omron switch‑mode power supplies. It explains how commercial AC power is converted to stable DC for electronic components and outlines the selection criteria for input voltage and output capacity.
Detailed sections cover terminology, input and output specifications, protection functions (over‑current, over‑voltage, leakage), parallel and series operation, remote sensing and control, harmonic current suppression, and wiring recommendations.
| Output Power (S82K) | 90 W / 100 W |
|---|---|
| Power Factor | 0.4 ~ 0.6 |
| Efficiency | Not specified (depends on model) |
Remove the shorting jumper between the FG terminal and the ACG terminal as shown in the manual.
The over‑current protection circuit shuts down the output to limit the current.
