Product Details：

Product Dimensions：

PHOENIX Filter Modules are designed for seamless integration into industrial control cabinets, mounting directly onto standard NS 35 DIN rails. These single-phase and multi-phase line filters suppress symmetrical and asymmetrical high-frequency noise generated by frequency converters, switching power supplies, and external grid disturbances. Advanced variants feature integrated Type 2 or Type 3 surge protection, protecting both the input and output sides of the filter. The module housings incorporate optical status windows and floating remote signaling contacts to allow real-time monitoring of internal protective elements within centralized control systems.

Product Advantages

Dual protection capabilities combine high-frequency noise attenuation and surge suppression within a single housing, eliminating the need for separate filter and arrester installations.

Extremely compact form factors, including ultra-slim 6.2 mm wide models, maximize available space on mounting rails in high-density control panels.

Integrated protective ground connections and dedicated PE terminals provide improved high-frequency noise dissipation directly to local equipotential bonding.

Maintenance effort is minimized due to optical visual diagnostics and dry changeover contact connections for remote fault signaling to supervisory PLCs or SCADA platforms.

Available Push-in terminal technology allows quick, tool-free wiring that reduces installation time and resists vibration-induced loosening over long-term operation.

Important Considerations and Precautions

Installers must strictly adhere to maximum continuous operating voltage limits, as overvoltage conditions exceeding rated thresholds will trigger permanent MOV degradation or thermal disconnection.

Line filters must be installed as close as possible to the protected equipment or cabinet entry point to prevent high-frequency noise from coupling back into clean wiring runs.

Ensure low-impedance ground connections by making the earth conductor as short and direct as possible, as poor earthing severely impairs filter attenuation efficiency.

Always verify that the line supply breaker or backup fuse rating does not exceed the maximum allowable back-up fuse specification stated for the specific filter model.

Never perform high-voltage insulation resistance testing or megger testing across lines connected to the filter without disconnecting the module first, as high voltages will trip protective components.

Product Applications

Programmable Logic Controller Power Mains: Filtering supply power entering PLCs, I/O racks, and industrial PCs to prevent processor resets caused by grid noise or inductive switching surges.
Sensitive Measurement and Process Instrumentation: Protecting flow transmitters, gas analyzers, weigh scales, and temperature transmitters from high-frequency signal interference.
Drive Systems and Motion Control: Suppressing switching noise generated by variable frequency drives and servo amplifiers from propagating back into control power circuits.
Telecommunications and MCR Technology: Protecting low-voltage MCR and data lines against transient overvoltages and noise in telemetry applications.
Industrial Cabinet Power Supplies: Installing directly ahead of 24 V DC power supplies to ensure clean AC input power and stable secondary voltage output.
