Product Description:
The 136N8921 is a variable-frequency micro drive produced by Danfoss within the VLT FC 51 Micro Drives series. Designed to control the speed of small AC induction motors, the unit converts fixed-frequency line power into an adjustable electrical output. This controlled output lets automated equipment regulate flow, pressure, or conveyor speed without relying on mechanical flow controls. The compact design is intended for low-power motor applications in control cabinets and automated machinery.
The drive delivers a continuous power rating of 0.37 kW, equivalent to 0.50 HP, making it suitable for fractional-horsepower pumps, fans, and small conveyors. Its input section accepts a line voltage of 200-240 VAC from a single-phase feeder, so it can connect to standard low-voltage utility circuits without a transformer. The enclosure carries an IP20 chassis rating, which helps prevent accidental contact with live parts when the drive is properly installed inside a control cabinet. The controller uses a coated printed circuit board that helps protect electrical traces from airborne moisture, conductive dust, and other contaminants commonly found around industrial equipment.
Adaptation A provides standard cable entries with metric gland openings, allowing power and signal conductors to enter the housing without additional drilling. The drive includes no brake chopper, so an external method of managing regenerative energy may be necessary when the connected motor must stop rapidly. The front panel has no local control panel, and parameter changes must therefore be made through compatible remote serial communication or PC-based tools. Adaptation B does not add optional equipment, and the drive has no additional mains option installed. The internal series index is 051, which identifies its position within the VLT Micro Drive product group.
