PF series universal feedback unit adopts Canadian technology to produce high-performance transmission energy-saving products from IPC Technology, using "flexible PWM technology", "LCL filter technology", "full voltage automatic tracking" and "zero point current" processing technology to improve the zero-crossing of the feedback current Under the premise of time current quality, feedback stability and power factor, the regenerative energy generated during the operation of the motor is fed back to the grid to achieve a saving effect. It has been widely used in elevators, cranes, mine hoists, centrifuges, oil field pumping units, wind power grid-connected power generation and other occasions.

(1) Using "LCL filtering technology", THD is less than 5%

(2) Support parallel mode, easily realize capacity expansion

(3) Intelligent fan control mode, more economical and energy-saving

(4) The comprehensive energy saving rate is as high as 20%~60%

(5) Using automatic phase sequence discrimination technology

Employing the automatic phase sequence identification technology, the phase sequence of the three-phase power grid can be connected at will, and there is no need to manually distinguish the phase sequence

(6) Built-in reactor and filter, plug and play

PF series universal feedback unit adopts integrated structure design, built-in reactor and filter, users do not need to purchase separately

(7) Completely replace resistance braking

PF can completely replace resistance braking, turning energy-consuming components into power-generating components, and can save more than 60% of installation space

(8) Eliminate potential safety hazards

Remove the heat-generating high-power resistors, greatly reduce the temperature of the production environment, and eliminate potential safety hazards

(9) Simple selection does not require tedious calculation of resistance, torque, etc.

Main circuit wiring method

Remarks: The main circuit wiring of the IPC-PF series feedback device is very simple. When this series of products are used in conjunction with the inverter, only the DC input terminals "DC (+)" and "DC (-) of the feedback device need to be correctly connected to For the positive and negative terminals of the inverter's DC bus, connect the AC feedback output terminals "A", "B", and "C" of the feedback device to the same power source as the input terminal of the inverter.
