The 1321-RWR35-DP module is a reflective wave reduction device from Allen-Bradley. It comes with an open type (IP 00) enclosure and an integral mounted, finger guard (IP 20) terminal block. This reflective wave filter operates with an input voltage of 400 to 480 Volts AC. Its fundamental amperage rating is 35 Amps. It has 414 Watts of heat dissipation. The maximum ambient temperature for the 1321-RWR35-DP reflective filter module is 45 degrees Celsius. It has a Class H (180 degrees Celsius or better) insulation system. Its approximate weight is 8.8 kilograms. The recommended drive carrier frequency for optimal 1321-RWR35-DP RWR module performance is 2 kHz.

In long motor lead applications, locating the 1321-RWR35-DP module between the drive and motor helps to reduce DV/DT and motor terminal peak voltage. Allen-Bradley RWR devices can help protect motors from fast DV/DT rise times that increase the motor insulation heat while reducing motor life over time. These reflective wave filters provide a simple solution by protecting motors from premature failures due to reflected wave impulses. It also helps to reduce voltage spikes, especially in long cable leads, and surge currents that are caused by rapid changes in the load. The most effective way to avoid reflected waves is to keep cable lengths shorter than the manufacturer’s recommended maximum length. When there is an application with a long drive to motor lead length, one of the best hardware solutions is to use a reflective wave filter that eliminates or reduces reflected waves. It also helps to extend semiconductor life and reduce audible motor noise. This device can be mounted on a panel while maintaining the minimum clearance for proper heat dissipation.
