OWON SPS Fanless Single Channel Programmable DC Power Supply

+ Fanless design: Ultra-quiet and reduces the vibration noise and potential failure risks of traditional cooling fans.

+ Excellent heat dissipation design:Long-term operation under full load conditions ensures controlled temperature rise for internal component longevity.

+ Lightweight and ultra-thin design.

+ Output accuracy up to 10mV/1mA.

+ Support List waveform editing and output,4 groups of memory shortcut parameters for quick output.

+ Integrated protection features include overvoltage, overcurrent,overtemperature and input undervoltage.

+ The output includes a built-in discharge circuit to prevent residual high voltage risks when the power is turned off.

+ Offers USB communication interface and supports SCPI protocol, allowing PC programming and remote control,simplifying user remote management.

+ 2.8-inch TFT LCD screen
