As a manufacturer of Braking Resistors, we are frequently asked by users, "Can braking resistors operate continuously for extended periods?" The answer depends on the product's design parameters and actual operating conditions. Not all braking resistors are suitable for long-term continuous operation; the key is whether their rated power and heat dissipation capacity match the requirements.
From a product design perspective, Braking Resistors are divided into two categories: short-time duty and long-time duty. Short-time duty braking resistors are designed for short-term operation (e.g., 1-5 minutes). If they operate continuously for extended periods, the heat cannot dissipate in time, leading to overheating and potentially burning out the resistor or shortening its lifespan. Long-time duty braking resistors, by increasing the heat dissipation area and using high-temperature resistant materials (such as aluminum alloy casings and corrugated structures), can continuously dissipate heat, meeting the requirements for continuous operation for more than 8 hours. They are suitable for scenarios requiring frequent braking, such as elevators and port machinery.
In actual use, if the equipment has a high braking frequency and a long single braking time, a long-time duty braking resistor should be selected, ensuring good ventilation in the installation environment. If necessary, a cooling fan or water cooling device should be used. We will specify parameters such as rated duty cycle and continuous operating time in the product manual to help users determine compatibility.
If you are unsure about the required operating time of the Braking Resistor for your equipment, or if you need a customized product for long-term operation, please provide us with information such as the braking frequency and single braking time. We will provide a precise product solution to ensure stable equipment operation.
