Product Description:

The 132L4590 is an AC variable frequency drive produced by Danfoss for the VLT EZ FC 321 Automation Drives series. In an automation cell, it changes motor speed by adjusting output frequency and voltage, letting pumps, fans, and conveyors match process demand while lowering energy use. This gives connected motors smoother acceleration and more flexible speed control than fixed-speed starters. User interaction is handled through the Graphical Local Control Panel, which offers direct parameter editing, plain text alarms, copy functions for cloning settings between drives, and local viewing of operating data.

The drive supplies up to 50 HP, which is equivalent to 37 kW. It accepts a three-phase 525–600 VAC mains feed, so it can be wired directly to standard 575 V industrial networks without an autotransformer. Enclosure protection is rated at IP20 chassis; live terminals are finger-safe inside a cabinet, and the heat sink remains open for forced or natural airflow. A built-in brake chopper clamps regenerated energy during fast deceleration, protecting the DC bus during stopping cycles and overhauling conditions. Because there is no RFI filter and no optional mains adaptation, line-side filtering or reactors must be provided externally when electromagnetic compatibility or harmonic mitigation is required.

Control boards use an uncoated PCB, so the unit is intended for clean electrical rooms rather than corrosive or high-humidity zones. The drive is supplied with latest release standard software and the standard language pack for compatibility with current Danfoss tools. Cable glands use standard cable entries for routine cable routing into the enclosure. The product also omits A, B, C, and D hardware options, leaving the standard baseline configuration without added mains or RFI accessories.
