DPH8920-RF programmable DC regulated power supply, the voltage is 0-96V, and the current is 0-20A continuously adjustable. The product is easy to operate and stable when in used. It can output accurate voltage and current, and has the high conversion efficiency, so it is widely used in laboratories, factory testing, power supply and maintenance of electronic equipment. |
►There are three ways to control the power supply:First, the button on the power panel can adjust the voltage and current; Second,the computer software communication regulates the voltage and current; Third, the remote control controls thepower supply wirelessly.
►The remote control has an effective control distance of 0-10 meters. A remote controller can control 30*99 power supplies by changing the communication channel and address.
►FreePCsoftware and communication protocol, the communication protocol is divided into "SIMPLE" and "MODBUS", which can be set in the power menu.
►The power supply is based on the BUCK architecture, and it can still work stably with the operating frequency up to 150KHz and the minimum 0.5V voltage difference.
►Input DC voltage 20-110V, the power supply can be powered by AC-DC switching power supply ,solar panels, wind turbines or battery-powered equipment.
►The maximum and minimum voltage and current can be set to protect the load from damage due to over-voltage.
►Equippedwith a temperature-controlledfan, intelligently adjusts the fan speed, and automatically cuts off the output after over-temperature.
►The voltage regulation response is very fast.
►The parameters are automatically saved when the power is turned off, and there are 10 groups of storage locations (M0~M9), which can be saved and recalled at any time.
