Product Description:

The NXL00125-C2H1SSS-0000 is an AC variable frequency drive assembled by Danfoss in the VACON NXP Air Cooled Drives series. This unit converts fixed-frequency, three-phase mains power into a modulated output that allows plant controllers to adjust induction motor speed and torque. Within an automation line, the drive regulates conveyors, pumps, or fan loads, allowing process throughput to be varied without mechanical throttling. The compact format and integrated power electronics make the model suitable for panel mounting in production machinery.

The enclosure is classified as IP21, so live parts are protected against finger contact and vertically dripping water is deflected when the unit is mounted upright. On 380 V networks, the inverter can deliver 5.5 kW of power, while both the continuous output current and nominal input current are rated at 12 A. The high-overload current rating is 9 A during continuous operation, while a line fuse rated at 16 A provides short-circuit protection. During a 10 percent overload, the current may rise to 13.2 A, and the control circuitry activates an internal brake chopper to manage regenerated energy. DC-link protection trips at 911 VDC on the high side and at 333 VDC on the low side, preventing component stress during supply fluctuations.

Thermal management requires an airflow of 70 m³/h to keep semiconductor junction temperatures within acceptable limits when the inverter handles a 50 percent overload current of 13.5 A. On 500 V supplies, the drive can support motors rated up to 7.5 kW, providing additional power capacity for high-speed machinery. The aluminum housing measures 128 × 292 × 190 mm and weighs 5 kg, so it fits in narrow control-cabinet columns without placing excessive mass on the mounting panel. Four mounting slots have holes with a diameter of 7 mm, accept standard M6 hardware, and position the heat sink fins in line with the forced-air path.
