The Allen Bradley 1336-RFB-27-B serves as an essential RFI input filter within the 1336 Adjustable series. This component functions by mitigating radio frequency interference and ensures that the AC mains supply does not introduce unwanted emissions to the connected drive, which enhances performance and compliance with standards. This filter accommodates 3-phase power systems and can operate under input voltages of either 200/240 VAC or 380/480 VAC.

Installation is straightforward, as the filter mounts directly on the panel alongside the drive itself. The design includes a power dissipation rate of 30 watts, ensuring effective operation under continuous use. The operational temperature range of this unit spans from a minimum of 0°C to a maximum of 50°C, allowing it to function effectively in standard industrial environments.

When it comes to storage, the filter is robust enough to withstand extreme temperature variations. It can endure temperatures from -40°C to 85°C, indicating its rugged design suited for various conditions. Additionally, it operates reliably in environments with relative humidity levels ranging from 5% to 95% without the risk of moisture-induced damage, contributing to its durability and longevity in different operational contexts.
