DRR SERIES - Delta DIN Rail Redundancy Module

Product Overview

DRR Series Delta DIN Rail Redundancy Module

The Redundancy Module DRR 20 and DRR 40 are the latest offering from one of the World’s No.1 Power Supply Company. The product offers a variable input & output voltage from 22-60V, a wide temperature range from -40°C to 80°C. The state-of-the-art design is made to withstand harsh industrial environments. The rugged, compact aluminium case is shock and vibration resistant according to IEC60068-2-6. Due to the wide input & output voltage range from 22 to 60Vdc, the Delta’s CliQ II Redundancy Module is able to support power supply in parallel operation. The DRR module has an alarm relay contact as an indicator.
