Ten laboratory power supplies can simultaneously display, current, power and other parameters. You can also see on the monitor screen its power source (CV), cross source (CC), short circuit protection (OCP) and turn on/off the output (OutPut) to know its operating status! Perfect gift for newborn parents, newborn mother, newborn father, baby shower, birthday, Christmas, festival and so on. 【Precise 4-digit LED】 Variable power supply with 4-digit high-resolution display that can display three values, current and power. The data is detailed up to 0,01V and 0,001A. Bright white digital display for easy work in the dark, and the fast screen can be applied as needed. 【Exit on/off button】 When used from the power supply, the operation can prevent forgetting to turn off the output and delay. Activate ten buttons to turn the power supply output on or off. This will make using the power supply more convenient. 【Overcurrent protection】 When the OCP function is on and a short circuit is started in the receiver during operation, the power supply automatically stops and sends a buzzer to alert the user. Protect the power supply and load from dangerous. 【High precision encoder knob】 DC power supply involved in the encoder. Share access to take over each digit, then rotate access in the 0-9 range to customize each digit. Electronic or current settings. The setting or current option can be switched by button (V/A).
