Energy Consumption Dynamic Braking Resistance Box Elevator Parts

Product application:

Suitabil for high-power,high current braking equipment,measure and test equipment,elevator,harbour machinery,lifting power brakecircuits of inverter etc...

Description of products:

BRB series braking resistor unit is used for motors in the slow process of renewable energy, in the form of energy consumption on the braking resistor, a inverter braking performance and shorten the inverter braking time.Mainly used in the converter drag system requires a sharp slowdown, brakes, positioning, etc;Inverter in the slowdown, due to the drag system of large inertia, the motor is in a state of power generation, mechanical energy rapid feedback to the dc bus, make dc bus voltage rise rapidly, so as to endanger the safety of the inverter, so the feedback energy must be consumed quickly, keep the dc bus voltage under a safe range, otherwise the inverter will overvoltage protection or malfunction.Generally large inertia, or need a sharp slowdown, the situation can use the brake unit.

Technical features:

1. Big power,small volume, strong-overload,shockproof abilityis strong,Low temperature rise
Small resistance rate;

2. Wide voltage range, Suitable for all kinds of voltage level of inverter, the voltage is adjustable continuously from DC250V to 1140V, Permissible to be used at places big grid change;

3. The design was correct , Selection of high-quality components, Plenty of hot redundancy guarantee, electromagnetic compatibility is complete, Suitable for harsh industrial environments. Have good human-machine interface, with simple and convenient operation.

4. The customer can be set up according to the mechanical characteristics of different and more suitable operation parameters and the startup mode, bus voltage and the running state of real-time display;

5. H ave perfect protection function(With short circuit, under voltage, overvoltage, over current, overheating, etc;

6. Structure of the firm, Strong vibration resistance, Easy to maintain.

7. long time operation, Winding resistance paint surface.

8. Original resistance diversification, winding resistance, Aluminum shell resistance, metal tube resistance, metal tube resistance Original high-power resistance are optional.
