Specifications

Description

The SAFUR 80F500 SAFUR80F500 is a high-performance dynamic braking resistor primarily used in variable frequency drive (VFD) systems to absorb and dissipate regenerative energy generated during rapid motor deceleration. This component effectively prevents DC bus overvoltage, thereby ensuring the stable and safe operation of the inverter.

Applications

Port machinery plants: Used for frequent starting and rapid braking of cranes, hoists, and other equipment.

Mining plants: Used for long-distance inclined conveyor belts and heavy-duty winch systems.

Steel and iron metallurgical plants: Manage regenerative energy for rolling mills and large production line drives.

Pulp and paper mills: Ensure the safe release of energy from winding systems during emergency shutdowns.

Elevator plants: Used for energy handling during descent or deceleration of traction systems.

Mechanical installation

Placing the brake resistors

Install the brake resistors outside the drive in a place where they can cool properly.

Arrange the cooling of the brake resistor in a way that:

1. no danger of overheating is caused to the brake resistor or nearby materials

2. the temperature of the room the brake resistor is located in does not exceed the allowed maximum.

Supply the brake resistor with cooling air or water according to the brake resistor manufacturer's instructions.

FAQ

Q: What is SAFUR 80F500 SAFUR80F500 SAFUR 80F500 SAFUR80F500?
A: It is a braking resistor.

Q: Must SAFUR 80F500 SAFUR80F500 SAFUR 80F500 SAFUR80F500 be installed inside a cabinet?
A: Not recommended. Due to extremely high operating temperatures (up to several hundred degrees Celsius), it is recommended to install it outside the cabinet in a well-ventilated area, ensuring there are no flammable materials nearby.

Q: Can a third-party resistor be used instead of SAFUR 80F500 SAFUR80F500 SAFUR 80F500 SAFUR80F500?
A: Yes, but the resistance must not be less than 6 Ohms, and it must have equivalent power dissipation and thermal protection capabilities.

Q: How to handle the inverter reporting "Brake Resistor Hot" in SAFUR 80F500 SAFUR80F500 SAFUR 80F500 SAFUR80F500?
A: Check the fan status (if any) or extend the braking cycle, waiting for the resistor to cool down naturally.

Q: Are there any special requirements for the wiring cable of SAFUR 80F500 SAFUR80F500 SAFUR 80F500 SAFUR80F500?
A: It is recommended to use a shielded cable of the same specification as the drive input power cable, and the length is generally not recommended to exceed 10–20 meters.
