178B1390 Danfoss Variable Frequency Drives (VFD)

Part number 178B1390 from Danfoss, listed in Variable Frequency Drives (VFD). KKM Solutions quotes this part with pricing and availability confirmed per order.

The 178B1390 is an AC variable-frequency drive manufactured by Danfoss for the VLT 2800 Low Voltage Drives series. In automated process lines it regulates induction-motor speed by altering output frequency, letting operators match torque to load while lowering energy use and mechanical stress. This model accepts a mains supply of 200-240 V AC , and its input terminals are designed for Single Phase power, a configuration suited to light industrial panels where three-phase service is unavailable. The inverter delivers a continuous mechanical output of 0.55 kW , which corresponds to 0.75 HP on the motor shaft, making it appropriate for small pumps, mixers, and conveyors. A protection category of IP20 indicates that the housing prevents finger contact with live parts but requires a clean, cabinet-mounted environment for safe operation. Physical layout and interface features support the drive’s role in space-restricted cabinets. The Bookstyle enclosure narrows the footprint so multiple units can be mounted side by side with minimal clearance. A Built In Display (SLCP) presents setpoints, status codes, and basic diagnostics without external tools. The drive is supplied without coating on its circuit boards, a detail acceptable in dry control rooms where conformal protection is unnecessary. Its hardware configuration is classified as Standard , meaning no optional I/O or application-specific firmware is fitted, which aligns with the catalog note of “no application option” and positions the product for general process-control duties.
