Frequently Asked Questions
What is the KRF filter's primary function?
The KRF filter reduces high frequency distortion and noise in the 150 kHz to 30 MHz range, protecting sensitive equipment from interference.
What system voltages are supported by KRF filters?
KRF filters support 480 VAC systems (applied to 240-520 VAC) and 690 VAC systems (applied to 600-760 VAC).
What are the amp ratings for KRF filters?
Amp ratings range from 8 to 2500 for 480V systems and 25 to 2500 for 690V systems.
What environmental conditions are suitable for KRF filters?
KRF filters can operate in ambient temperatures from -25° to 100° C and at altitudes up to 1,000 m without derating.
What types of equipment can benefit from KRF filters?
KRF filters are useful for motor drives, elevators, commercial buildings, wind farms, photovoltaics, UPS, and power supplies.
What is the overload rating for KRF filters?
The filter can handle 150% of rated current for 3 minutes every 60 minutes, or 250% for 3 seconds every 60 minutes.
What common issues can KRF filters help prevent?
They help prevent computer system failures, remote I/O glitches, encoder errors, and other disturbances caused by power line noise.
What agency approvals does the KRF filter have?
The KRF filter has ENEC and UL Recognized agency approvals.
What are the termination options for KRF filters?
KRF filters are available with Termination Block (TB) or Copper Bus (CB) terminations.
How does the KRF filter reduce high frequency distortion?
It uses inductors that act as open circuits and capacitors that act as short circuits at high frequencies.
