Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few dual power supply manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom dual power supplies has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

Two digital panel meters (LED). Constant voltage and current operation. Output switch off function (output standby). Overload and reverse polarity protection. High power density. Use the Dual 48 VDC power supply to power your Datacom Systems’ network taps, multi-link aggregators and SPAN port regenerators. The Dual 48 VDC power supply accepts connections on terminal block connectors for 48 VDC plus (+), minus (-) and ground connections. DC power jack cables are provided for connectivity from each power supply to the network tap, multilink aggregator or SPAN port regenerator. Each DC input terminal block connector provides a 5 Volt output. The dual power supply can be used for fault tolerant redundancy. Dual 48 VDC inputs. Dual 5 VDC outputs. 2 (two) 5 VDC cables included. Includes convenient rack mount ear. Optional 1U rack mount holds 3 power supplies.
