30V 10A 300W Mini Portable Digital Power Module Multifunctional Power Module Multiple Protections Aluminum Alloy Digital Power Module with OLED Display The mini digital power supplys has a built-in cooling fan, and the maximum output power of each channel can reach 300W, which can meet a wider ranges of use requirements and application scenarios. Through 2.4G wireless communication, it can be connected with intelligent display and control module to realize free combination of 300W multi-channel per channel. Features: Through 2.4G wireless communication, it can be connected with intelligent display and control module to realize free combination of 300W multi-channel per channel. The built-in silent, intelligent temperature-controlled cooling fan can achieve quick heat dissipation and ensure stable and efficient output. Support direct current 4.2V-30V wide voltage input (direct current 5.5/2.5 interface), support 20V PD quick recharging protocol power supplys, high compatibility. 95% high-efficiency programmable linear output, the output power can reach 300W. The built-in high-performance MCU chip supports the use of multiple machines in series or parallel to meet the needs of ultra-wide power supplys. With custom input current limiting, undervoltage protections, voltage drop compensation, strong mode and other functions, it can meet diverse test needs. Multiple protections functions: with input overvoltage, undervoltage protections, reverse connection protections, overcurrent protections, backflow protections, and overtemperature protections. Support USB firmware upgrade to update your device in time. Multi-purpose: suitable for general testing and teaching experiments in R&D laboratories, maintenance of digital products such as mobilephones and notebooks, power supplys testing and data recording of radios frequency, microwave circuits or modules, characteristic verification and fault diagnosis of devices and circuits, quality control and quality Inspection, digital products, emergency power supplys, etc. Two types optional: The main host can achieve the above functions, and the intelligent display and control module is  for you e with the host.
