An assembly-type power resistor enclosure contains DR series of and/or DQ series resistors. The box offers excellent protection and safety, in that it not only provides high power load capability and durability, excellent heat dissipation, and a low temperature coefficient that is directly proportional, but also accommodates a flexible range of assembly options for convenient utilization and installation (Refer to the DR series and DQ series features for exact specifications). Suitable for educational modeling applications, load testing, industrial machinery, electric power distribution, instruments and automation control installations, etc. For custom specifications, please contact us to discuss the details.
