They are braking resistor modules that aim to ensure maximum protection of your critical loads by increasing the operating performance of the device in re-generative loads such as CNC Machines, Electric motor loads, and to reduce your cost of ownership by extending the working life of durable materials such as batteries and capacitors.
TESCOM offers solutions for all types of UPS with different braking modules according to the appropriate UPS power.
An example of such loads is electric motors. Electric motors draw current from the network while rotating, but in case of a sudden force (braking effect) they start to produce electricity themselves, this energy is sent back to the source they are fed.
If the electric motor is supllied by the UPS, in the braking mode, the UPS applies extra energy to the DC BARA through the reverse diodes of the output power transistors, which causes the DC BUS voltage to rise.
By connecting to the DC bus of the UPS, when the allowable limit value in DC rises is exceeded, it activates the resistor loads with the help of contactors driven by a transistor on it, providing the necessary voltage drop and converting the excess energy into heat energy.
In regenerative load applications (CNC Machines, Electric Motor Loads), it is recommended to use a DC Brake Unit in order to absorb the DC voltage that is pressed back into the mains (UPS) during braking.
