Application Examples: Printers, scanners, desktop phones, network
switches (non-core models).
Solution Requirements: Ensure stable, interference-free operation
of these devices within complex office electromagnetic
environments.
4. Industrial Control and Automation (Auxiliary Equipment)
Application Examples: Auxiliary power supplies for PLC modules,
sensors, small human-machine interfaces (HMIs), industrial
controller peripherals.
Solution Requirements: Deliver cost-effective, reliable EMC
protection for low-power devices within space-constrained
industrial control cabinets, enhancing system immunity to
interference.
