2D QR Code Scanner Wireless BAR-2DCWL04

Meet the needs of 380-480V three-phase power grids including Europe, North America, India, etc.

The maximum output frequency under vector control is 500Hz, which can achieve high-precision speed output within 10 times the field weakening speed range.

0.4kW-75kW(G) built-in braking unit; strong braking ability: short-term braking can reach 1.1-1.4 times the stable power of the frequency converter; braking protection is more comprehensive. Intelligent: with brake resistance short circuit protection, brake circuit overcurrent protection, brake tube overload protection, brake tube through detection belt

In the closed-loop vector mode, the torque linearity deviation is within 3%, the torque output is stable, the low-frequency torque is large, and it can achieve ultra-low speed 0.01Hz stable driving with load. The torque mode and speed mode can be easily switched. Perfect DC braking circuit scheme.

The design with independent air duct can prevent dust from entering the inverter effectively,avoid failures by short-circuit , and improving reliability; the long-life cooling fans with large air volume can effectively reduce the temperature rise of the inverter and ensure the reliable and stable operation of the inverter.

It can avoid over-current faults caused by direct start and realize a smooth start; it can reduce the impact of instantaneous power failure on production; it can reduce the impact on the grid.

Through the voltage flux vector algorithm, the closed-loop control of the output voltage is realized; when the motor torque requirement is low, the excitation current is reduced according to the load current; the motor efficiency is maximized; the motor loss and energy loss are reduced.

Real-time monitoring of the load current passing through during operation automatically limits it to not exceed the set overcurrent suppression point to prevent fault tripping caused by excessive current. This function is especially suitable for some loads with large inertia or severe changes.

60s at 150%, 10s at 180%, 0.5s at 200%; overload protection is more powerful.
