1. Solid material, input adopts a common-mode inductor, significantly reduce the impact of the input power supplys wavenumber, to achieve low wavenumber output. 2. Intelligent temperature control design, fan with large area heat sink, with superior heat dissipation effect. 3. Output voltage can be set by dip switch, with the fixed voltage output of 5/9/12/24/36/48/60V. 4. And the base plate can be used independently, the output current of 0-20A, the back of the base plate with true value table. 5. Low-cost communication power supplys, through a TTL to 485 module or WIFI module, it can realize the remotely controls of multiple machines, a separate base board can realize communication control, low-cost solution.
