Factory wholesale Neutral Ground Resistor Purpose - Braking Resistor Box for converter resisotor, inverter resistor – Wepower
Factory wholesale Neutral Ground Resistor Purpose - Braking Resistor Box for converter resisotor, inverter resistor – Wepower Detail:
█ Description:
Resistance boxes are used to add resistance in to an electric motor circuit for modifying the performance characteristic of slipring induction motors of EOT cranes, rubber mills, steel rolling mills, cement mills, power plants, conveyors, coke oven, blowers etc for speed control and developing staring torque with low starting currents.
They are also used as Dynamic breaking resistor for VVVF. A.C. Drives electric loading of ac alternators, de generators and dynamometers. Resistors are designed to meet requirements of both A.C. and D.C. Applications.
The RBRU series of products are resistor boxes that are assembled with Wire Wound Resistor and are applicable to power-consuming circuits of inverter for braking equipment with large rated power and current, testing equipment, elevator and crane.
█ Important Notice:
All kinds of brake resistors manufactured by Teamwill can be customized for customers, our products are widely used in ship and military industry, photovoltaic, wind power generation, ports, oil drilling, industry transmission, rail transit, new energy vehicles, etc.
