STF4402B Programmable DC Power Supply

STF4402B is one quadruple output programmable DC power supply. It has 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.

STF4402B power supply 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 **
