🔌 Why use multiple components when one module can do the job?

For equipment manufacturers, the AC power entry is more than just a connector.

A well-designed Power Entry Module can integrate essential functions such as:

• IEC power connection
• EMI filtering
• Fuse protection
• Power switching
• Terminal connections

That means fewer individual components, simpler panel design, easier assembly, and a more compact power input solution.

DOREXS Power Entry Modules are designed for OEM equipment manufacturers, industrial automation, medical equipment, test instruments, and other electronic systems.

Need a customized configuration?

We can support customization of voltage, current, EMI filtering, fuse, switch, terminals, mounting dimensions, housing, labeling, and cable length.

⚠️ Your equipment isn't failing because it's poorly designed.

It may simply be missing the right EMI filter.

Three-phase industrial systems generate significant electrical noise, especially when using:

⚡ VFDs
⚡ Servo Drives
⚡ Inverters
⚡ Industrial Controllers

Without effective EMI suppression, that noise can affect both your equipment and everything connected to it.

The DOREXS 10A Three-Phase EMI Filter helps reduce conducted interference, improve system stability, and support EMC compliance—making it an ideal choice for industrial OEM applications.
