Product Description:
The 136N8941 is a variable-frequency micro drive produced by Danfoss within the VLT FC 51 Micro Drives series. This chassis-mounted inverter modulates AC power to regulate induction motor speed in compact conveyors, pumps, and general industrial automation where cabinet space is limited. It belongs to the VLT Micro Drive product group and carries the 051 internal series code, so its frame dimensions and terminal layout remain consistent with related models. The drive provides essential speed control for applications that do not require advanced communication or harmonic mitigation options. Its compact format supports installation in control cabinets where available mounting space is restricted.
The power stage delivers up to 22 kW of continuous output, allowing the drive to operate midsize motors without derating under normal conditions. It accepts an input supply of 380–480 VAC from a three-phase mains network and tolerates common plant voltage variations within that range. The enclosure meets the IP20 touch-safe classification, which protects against finger contact with live internal parts when the unit is installed inside a cabinet. Integrated dynamic braking is provided through a built-in brake chopper, allowing regenerative energy to be dissipated through an external resistor during rapid deceleration. This arrangement helps manage energy returned by loads with high inertia or frequent stopping cycles.
The factory configuration uses standard cable entries, allowing wiring glands to align with conventional metric knockouts. The control electronics have a coated printed circuit board that protects copper traces from airborne oil and moisture in humid process areas. No local control panel is fitted, so operation and parameter access require a compatible external interface or control connection. The drive does not include special adaptation modules, leaving the standard control arrangement available for basic motor-speed applications. It is also supplied without a mains filter option, which keeps the installed configuration focused on essential inverter functions. These features allow power, motor, and control wiring to be routed through a compact chassis without additional integrated option hardware.
