Description
Application Scenarios
Picture a system integrator building a packaging machine for a European customer. The control cabinet houses three PowerFlex 525 drives, a CompactLogix PLC, and a vision sensor that inspects bottle labels at 120 frames per second. During factory acceptance testing, the machine fails EMC pre-compliance: the vision sensor loses lock and the PLC logs sporadic communication timeouts whenever the drives ramp a conveyor. Rather than redesign the cabinet, add expensive shielding, or reroute every cable, the integrator installs a 25-RF7P5-AL on the input power terminals of each Frame A drive. The integrated LC filter network immediately attenuates the high-frequency conducted noise, and the machine passes certification cleanly — no cabinet redesign, no delays, no rewritten bill of materials .
Now imagine a water treatment plant that has just retrofitted its raw-water pump drives to PowerFlex 523 units for an energy-saving project. The new VFDs run beautifully, but the plant’s flowmeters and pressure transmitters — and with them the chemical dosing logic — begin showing erratic readings whenever a pump starts. The culprit is conducted EMI riding the 24 V DC control circuits and communication lines. Retrofitting the existing drives with the 25-RF7P5-AL suppresses that line-borne interference, restoring accurate telemetry and allowing the plant to return to precise, compliant chemical dosing. In both stories the value of the 25-RF7P5-AL is the same: it turns a hidden, expensive compliance and reliability risk into a predictable, off-the-shelf line item.
Parameter
| Main Parameters | Value / Description |
|---|---|
