Frequently Asked Questions
What is the purpose of a braking resistor with variable frequency drives?
Braking resistors are used with variable frequency drives for applications requiring faster deceleration or when motor speeds exceed synchronous speed, dissipating regenerated power to prevent bus voltage from exceeding drive limits.
What is the purpose of a braking chopper (module)?
Braking modules monitor the DC bus of the drive and activate external braking resistors to dissipate regenerated power, preventing over-voltage trips and improving system performance.
What is the voltage range for ACS150 and ACS355 three-phase drives?
The ACS150 and ACS355 drives are available for three-phase 200-240V and 380-480V applications.
What is the voltage range for ACS250 three-phase UL Type 4X drives?
The ACS250 UL Type 4X drives are available for three-phase 200-240V and 380-480V applications.
What is the voltage range for ACS550 three-phase drives?
The ACS550 drives are available for three-phase 200-240V and 380-480V applications.
What is the voltage range for ACS150 and ACS355 single-phase drives?
The ACS150 and ACS355 drives are available for single-phase 200-240V applications.
What is the voltage range for ACS250 single-phase drives?
The ACS250 drives are available for single-phase 100-120V and 200-240V applications.
What is the voltage range for ACS250 three-phase drives (non-UL Type 4X)?
The ACS250 drives are available for three-phase 575-690V applications.
What is the function of the thermal switch in enclosed resistor units?
The normally closed thermal switch detects resistor temperature overloads, providing a safety mechanism to prevent overheating.
When should 200ºC rated wire be used with Type ED enclosures?
200ºC rated silicone or Teflon wire should be used when attaching directly to resistor coils if installing without the optional terminal connections.
