Product Description:
The VACON0020-3L-0012-4+EMC2+QPES+DLFR Drive from Danfoss offers enhanced reliability with automatic fault recovery and smooth start/stop with DC brake control. It performs efficiently on a stable 3 phase electrical supply for industrial automation applications.
The VACON0020-3L-0012-4+EMC2+QPES+DLFR drive comes with an adjustable switching frequency feature. It is housed in an enclosure rated as IP20 which means it is safer from solid objects larger than 12 mm and it also meets safety standards defined by UL. It is rated to operate in environments where the relative humidity is less than 95 percent as long as there is no condensation. It comes with a simple logic which allows users to program custom start, stop and reverse behavior based on external signals. It sets the nominal operating frequency of the motor to 50 hertz which is typical for many industrial and residential applications worldwide. Its continuous current rating is 3.3 amperes over long periods without overheating or damaging internal components. It features a brake chopper that controls the regenerative energy produced by the motor during deceleration. It includes a programmable U / f curve feature which allows for custom control over the voltage to frequency relationship.
This VACON0020-3L-0012-4+EMC2+QPES+DLFR drive EMC2 rating means it meets specific standards for electromagnetic emissions. It uses the motor pre heat function to warm up the motor before it begins its full operation. The maximum power it can handle during periods of high overload is 5.5 kW without damaging the motor or the drive itself. It can function between 380V to 480V AC which allows for variation in the power supply. Its allowable storage temperature range is -40…+70 °C which makes it well suited for harsh environments.
