RUZIZAO Bench Power Supply Variable: 30V 10A 300W Lab DC Adjustable Switching Regulated with OCP & OVP Function, Output Button, Encoder Knob

Newly Added OCP OVP Button: The bench power supply can manually preset the maximum output current and voltage values, when the output value exceeds the preset value, the benchtop power supply will start the short circuit protection to protect your equipment. The new OCP OVP button allows the maximum output current and voltage values to be set manually and can be calibrated to improve overall accuracy 2025 Upgrad Encoder Knob: Compared to the original two encoder knobs, we upgraded to four high-precision encoder knobs. It can precisely set the current and voltage values required for coarse and fine adjustments. The encoder knob with fine have a new mute function, turns off the beep when pressed for five seconds. Encoder knob replaces the potentiometer switch. Pressing the knob toggles the digits, and rotating the knob sets each digit in the 0-9 range with resolutions up to 0.01V and 0.001A Output Switch Button, USB Port: DC power supply can directly preset for current and voltage. Sometimes we need to switch between different voltage or current outputs, but often forget to unplug instrument, resulting in instrument burnout, a situation that often occurs in maintenance testing. The output switching function can effectively prevent damage to your equipment or load. 5V/2A USB port provides a stable output of power to charge your devices CE & FCC Certification, Wide Applications: 30V 10A Lab power supplies have passed CE & FCC Certification. This benchtop power supply is suitable for battery charging ( LiFePO4, lead-acid battery, etc.), labs, schools, electronics repair, electrolysis, electroplating, lamp testing, aging testing, DIY, communication equipment maintenance, products line, scientific research and teaching units.
