1220-2758-02

The 1220-2758-02 braking resistor from Control Techniques is engineered for the Unidrive SP series, providing essential support for energy absorption in power applications. With a nominal resistance setting between 20 and 30 ohms, it is suitable for dissipating excess energy efficiently. The rated voltage can reach up to 600V, accommodating a variety of system requirements.

This braking resistor is available in power ratings ranging from 50 W to 300 W, allowing flexibility in performance. It can function effectively in environments with operating temperatures extending from -10°C up to +50°C. Furthermore, storage conditions can vary from -20°C to +70°C, making it adaptable to different operational settings.

Weighing just 0.5 kg, this unit can handle energy absorption of up to 10 joules per pulse. The IP20 rating of the enclosure offers basic protection against solid objects but is not designed for moisture exposure. Additionally, it features an overload protection mechanism for enhanced safety while in operation. Communication is established via RS485 utilizing the Modbus RTU protocol, facilitating ease of integration into existing control systems.

The resistor can be conveniently mounted using DIN rail or panel installation options. With dimensions of 140 mm in width, 180 mm in height, and 150 mm in depth, it is compact enough for various installation environments, aligning with diverse needs in industrial settings.
