Product Description:
The VLT 2800 is a low-voltage variable frequency drive built by Danfoss for the VLT 2800 Low Voltage Drives series. As a compact inverter, it converts fixed three-phase mains power into a modulated output so asynchronous motors can be speed-controlled in conveyors, pumps, and general factory machinery. The drive provides controlled motor acceleration, deceleration, and energy-saving speed regulation within automated systems.
Within the control circuitry, the drive supplies a 24 V DC auxiliary rail that can provide up to 130 mA for sensors. The analog command channel has an accuracy of 1% of full scale and uses a 10-bit converter for speed references. Five isolated digital inputs accept up to 28 V DC, while the pulse feedback ports accept signals at frequencies up to 67.6 kHz. Output frequency accuracy remains within 0.2%, and the output frequency reaches a maximum of 10 kHz. Motor power is rated at 11.0 kW, which is equal to 15 HP, and the true power factor is 0.90. Stable operation is possible with a supply imbalance of ±2.0%. The internal relay switches 250 V AC at 2 A, with a capacity of 500 VA, and the transistor output supports an unlimited number of switching operations. A 10 mm² grounding conductor is required for fault clearance.
Heavy-load starting conditions are supported by a torque surge of 180% for 0.5 seconds, which allows the inverter to start conveyors or compressors with high breakaway friction. When dynamic braking is required, the integrated chopper terminal tolerates up to 850 V DC, so energy generated during rapid deceleration can be dissipated through external resistors without causing an overvoltage trip. For line-fault protection, the unit is tested to withstand prospective currents of 100,000 A, allowing installation on industrial feeders protected by high-capacity fuses.
