Frequently Asked Questions

What is the purpose of a braking resistor with variable frequency drives?

Braking resistors are used to increase braking torque capability, producing faster and more controlled braking. They dissipate regenerated power to prevent bus voltage from exceeding the drive's rated limit.

What is the purpose of a braking chopper (module)?

Braking modules monitor the drive's DC bus and activate external braking resistors as needed to manage regenerated power and avoid over-voltage trips.

How are Powerohm Type CR resistors constructed?

They feature a nickel-chromium wire helically wound inside a ceramic fixture, placed in a corrosion-resistant aluminum case. Coil ends are terminated to high-temperature wire leads and encapsulated.

What is the voltage range for ACS150 and ACS355 single-phase applications?

These drives are for single-phase 200-240V applications.

What is the voltage range for ACS150 and ACS355 three-phase applications?

These drives are for three-phase 200-240V and 380-480V applications.

What is the voltage range for ACS250 single-phase applications?

These drives are for single-phase 100-120V and 200-240V applications.

What is the voltage range for ACS250 three-phase applications?

These drives are for three-phase 200-240V and 380-480V applications.

What is the voltage range for ACS550 three-phase applications?

These drives are for three-phase 200-240V and 380-480V applications.

What is the function of the thermal switch in Type GCE and ED enclosures?

A normally closed thermal switch is provided to detect resistor temperature overloads and alert the system.

When should 200ºC rated wire be used with Type ED enclosures?

If installing without optional terminal connections, always use 200ºC rated silicone or Teflon wire when attaching directly to resistors.
