9509, KBRF-250, CE Approved AC Line Filter (Class A) Mounts Under KBVF and "L" Bracket Controls
The KBRF-250 is a Radio Frequency Interference (RFI) filter designed to suppress electrical noise generated by motor speed controls, including systems using SCRs, transistors, PWM, and inverters. These systems often generate high-frequency switching noise, which can:
-
Travel through AC power lines.
-
Radiate from wires acting as antennas.
-
Cause interference in sensitive electronics, especially in the AM radio band (0.5 MHz – 1.5 MHz).
Compliance
-
Meets CE Directive 89/336/EEC.
-
Designed to satisfy EMC Class A Industrial Standards (suitable for industrial environments).
Design Features
-
Integral mounting base designed for direct mounting of speed controls (e.g., KBVF Series, PWM DC, SCR speed controls).
-
Includes 8 threaded mounting holes (10-32) for flexible mounting configurations.
-
Housed in a plated steel case for shielding.
-
Requires grounding via external ground screw or mounting tab.
-
Quick-connect terminals for easy installation.
