Key Features 4-digit display for voltage, current and power Output ON/OFF control Panel lock button OCP over‑current protection OVP over‑voltage protection Rear panel high‑current output terminals Encoder knob for precise adjustment 4 groups of memory presets (M1~M4) Knob buzzer with mute function Standard USB & RS232 ports (RS485 optional) Performance & Usability Built for precision and long‑term durability, this unit features a high‑definition 4‑digit display that shows real‑time voltage, current, and power values for clear and accurate monitoring. The precision encoder knob supports smooth and fine tuning of output parameters. The 4 groups of quick memory buttons (M1–M4) store frequently used voltage and current settings, greatly reducing repetitive setup and improving production efficiency. Safety & Protection Safety is fully guaranteed by integrated OCP (Over‑Current Protection) and OVP (Over‑Voltage Protection), which automatically trigger in overload, short‑circuit, and over‑voltage conditions to protect both the power supply and connected equipment. Additional user‑friendly functions include an output enable switch, a panel lock to prevent accidental misoperation, and a buzzer with mute mode for quiet operation in industrial environments. Interface & Application Equipped with a rear‑panel high‑current output for secure and high‑power wiring, the unit also includes standard USB and RS232 communication ports (RS485 available upon request). These allow easy integration into automated production systems for remote control, data recording, and intelligent process automation. With its rugged structure, strong heat dissipation, and complete protection system, the KUAIQU R‑SPS30010S‑232 is the ideal choice for electroplating factories, industrial manufacturing, production testing, equipment maintenance, and heavy‑duty electronic R&D applications. Notes If the DC power supply becomes overheated, stop using it and allow it to cool down before resuming operation to avoid irreversible damage to the device. The front panel is only suitable for output currents below 5A. To avoid damaging the power supply or load and ensure more accurate output, please connect the high-current terminals on the rear panel for currents above 5A. The rear panel supports the full rated current of your model: for example, if you purchased a 300V 10A power supply, the current can reach 10A when using the rear high-current terminals.
