Description The OWON SPS3081 Fanless Programmable DC Power Supply (120 W) delivers ultra-quiet, high-precision performance with 10 mV/1 mA accuracy and advanced heat dissipation for long-term reliability. Featuring comprehensive protection, a USB interface with SCPI support for remote control, and a 2.8-inch TFT LCD screen, it is the perfect choice for laboratories, electronics testing, and research.
Features
Fanless design: Ultra-quiet operation, reducing vibration noise and minimizing the potential failure risks associated with traditional cooling fans.
Excellent heat dissipation design: Ensures a controlled temperature rise, allowing long-term operation under full load conditions and extending internal component longevity.
Lightweight and ultra-thin design.
Output accuracy up to 10 mV/1 mA.
Supports List waveform editing and output, with four memory shortcut parameters for quick and convenient access.
Integrated protection features include overvoltage, overcurrent, overtemperature, and input undervoltage protection for enhanced safety.
Built-in discharge circuit prevents residual high voltage risks when the power is turned off.
USB communication interface with SCPI protocol support, enabling PC programming and remote control for simplified user management.
