STF4400 Series Programmable DC Power Supply

STF4400 series multiple output programmable DC power supply cover 4 models (15W-180W), each power supply has the function of triple voltage and triple current output ranges. The whole series of power supplies have the functions of serial, parallel and synchronous output between channels, and the output parameters of all channels are displayed on the same screen, which is more convenient and intuitive to use.

STF4400 series can be used in various areas, such as R&D and design verification common test, production line table routine testing and maintenance, automated device integration testing, solar photovoltaic simulation test, new power car simulation test, and teaching laboratory etc.

** Standard Lead Time: within 4 weeks **
