Product Description:
The 178B1570 is a frequency converter produced by Danfoss within the VLT 5000 Frequency Converters series. As an AC drive, it generates variable output frequency and voltage so three-phase induction motors can match process demands instead of running at a fixed utility frequency. This regulation supports energy savings and precise torque control in conveyors, mixers, and similar automated equipment. The unit is intended for cabinet installation in general industrial environments, where its enclosure can be protected by the surrounding electrical cabinet.
The converter accepts a 380–500 V three-phase supply, making it compatible with common industrial power distribution systems. Regulation is handled by an internal process control card that manages pulse-width modulation patterns, monitors faults, and provides digital references. The converter provides a continuous motor output of 18.5 kW for applications using 110% overload torque for one minute. Reliability in areas with airborne contaminants is improved by coated circuit boards that protect conductive tracks from condensation and dust. All electronics are contained in a compact IP20 housing suitable for installation inside a ventilated electrical cabinet. A front-panel display supports parameter entry and operating-status review, while an external RFI filter can be added when conducted or radiated emission suppression is required.
For duties that require 160% torque, the drive provides a sustained output rating of 15 kW, allowing it to accommodate high peak demands while operating from a lower thermal base. Regenerative energy produced during braking is managed by a factory-installed standard brake chopper, which routes excess DC-bus power to an external braking resistor. Network connectivity is limited because the converter has no fieldbus option, so communication must use the interfaces available in the base configuration. The application slot has no built-in option, leaving auxiliary functions dependent on compatible external equipment or separately installed accessories. These interface arrangements keep the base unit focused on motor regulation, local parameter access, fault supervision, and braking control without adding an integrated industrial network module.
