The carrier frequency range of GD5000 is 0.8KHZ-1.2KHZ.

120% of the rated current: 120S,150% of the rated current: 5 s.

 1) The inverter outputs three levels for each phase, so that the line (phase) voltage has more step waves to simulate sine waves, and the output waveform distortion is reduced;
2) The output voltage change rate (du/dt) is low, and the voltage spike is low, which can reduce the damage to the motor insulation;
3) The use of three-level inverter can effectively reduce the common mode voltage at the motor end, thereby reducing the voltage end shaft voltage and shaft current, and reducing the damage to the motor bearings;
4) Low three-level harmonic content, reducing EMC costs
5) Low three-level loss at the same carrier frequency, reducing heat dissipation costs;
6) Reduce the inductance of the feedback reactor and increase the sine of the input side waveform, which is more suitable for four-quadrant applications;
7) The reverse voltage of the IGBT is half of the DC bus voltage. For example, a 1140V inverter can use a 1700V IGBT, which has high reliability

INVT can find partners to provide heat pipes and backplanes.

INVT provides communication drawings corresponding to the Machine core (peripheral dimensions, opening size, movement loss, etc.). Customers carry out heat pipe/water cooling plate/back plate design and need to send the heat pipe + back plate to INVT. Install the Machine core with the heat pipe and back plate, complete the factory test, pack and ship, and hoist it into the explosion-proof shell after the customer receives the goods

Two-quadrant machine core comes standard with rectifier unit + inverter unit, and four-quadrant products come standard with front LCL + rectifier unit + inverter unit

1140V two-quadrant VFD is a standard 6-pulse rectifier, 3300V two-quadrant VFD is a standard 12-pulse rectifier, but a phase-shifting transformer is required；

GD3000 are equipped with Modbus as standard and support extended Profibus;

Support the master-slave control mode. Each inverter needs to be equipped with a CAN master-slave card，and it support the master-slave speed mode and torque mode.
