Product Features:
Senlan SB70 seriesfour-quadrant vector control inverter is applicable to potential energy load orsharp slowdown large inertia load. It feeds regenerated energy generated in thebraking process back to grid, enabling two-way flow of energy. Without energyconsumption braking unit and braking resistor, regenerated energy will not beconsumed in the form of heat energy, resulting in greater energy efficiency andmore stable and reliable slowdown. The use of the IGBT PWM rectifier technologyenables optimized SVPWM control algorithm and the power factor close to 1,reducing the harmonic pollution on the grid. This makes it a green inverter.
Applications:
Applicable to potentialenergy load, e.g. downward belt conveyors of mines, pumping units of oilfields, mine hoists and lifting equipment at ports, or high inertia load, e.g.centrifuges, cement pipes, dynamic balancing machine, planing machine, aachinetool spindle and other occasions that require fast stop.
