Weight: 1.68 kg Item Description Programmable: Variable DC power supply with USB-B connection port on the back for fast and accurate voltage/current adjustments, setting multiple memory values, exporting data tables/graphs via PC; with hardware list, with programmable sequence outputs and more. Wide Range Power Supply: This programmable power supply can output up to 40V voltage 20A current, compared with other 300W power supplies, it has a wider output range, which is multi-purpose, energy-saving, scalable and wide range. It perfectly replaces various specifications in the market, for example, it can output 30V5A, 30V10A, 15V20A and so on. You can dynamically adjust the voltage and current according to your needs. TFT screen with Multi-function display: Full viewing angle, high precision 4-digit display for voltage (output voltage set value and actual output value), current (output current set value and actual output value), actual output power, totalized execution time, channel output status, OCP/OVP switching status. The data is very intuitive and easy to understand. Precision encoder knob and direction key: Unlike other DC power supplies this adjustable power supply can be adjusted using two ways: high precision knob and direction key, which can meet different usage habits, support coarse and fine adjustment, and can set the required voltage or current more precisely. Make your work more flexible and efficient. Memory storage, key: Bench DC power supply with 3 sets of data storage buttons, 1, 2, 3, you can set the commonly used data for storage as a shortcut parameter, and then turn on the DC power supply can be used again with one key, very convenient. With menu button, with up and down buttons can set U/I shortcut parameters. Features: Programmable with USB-B port, connected to a computer for remote or automated control. Supports USB, RS232, and RS485 interfaces. Please contact us if needed. Wide range voltage Adjustable and output stable DC power supply with two adjustment methods: high-precision knob and directional key. 3 sets of quick parameter storage keys: can preset the voltage and current values when the output is turned off, and can quickly call up the pre stored values of 1/2/3, making it convenient and flexible. It has four protection functions: overvoltage protection (OVP), overcurrent protection (OCP), over temperature protection (OTP), and overload protection (OPP). Front 5V2AUSB charging interface. One click output on/off, one click voltage and current stabilizing switch, automatic locking menu key to prevent incorrect operation. TFT color screen LCD 4-bit display, 360 full view view. The panel can simultaneously display the output status, output current, voltage, power, and display time, as well as the switch status of overvoltage protection (OVP)/overcurrent protection (OCP). Can support global voltage adjustment: 110V/220V.
