High-precision voltage / current control
The OWH80Q Series offers a wide-range output (80V/20A/2000W), with all four channels supporting high-power 500W output. lt integrates high-precision control, long-term stability, high relability and low thermal drift into a single platform delivering up to 0.05% voltage and current setting accuracy to meet demanding testing applications.
Powerful List Mode
The OWH80Q Series is equipped with a powerful LiST function, which supports independent output waveform for each
channel and synchronized configuration of multi-channel timing relationships.Through a user-friendly interface, users can flexibly edit and execute sequences of up to 100 steps. USB file import is also supported, greatly simplifying the configuration and management of complex testing processes.
Waveform Display
OWH80Q series provide waveform display function, it is convenient for users to capture the abnormal situations and realize power supply and scope functions.
USB Data Logging & Screenshot
OWH80Q series provide USB screenshot and recording local storage function, it is convenient for user to monitor the abnormal data up to 72 hours long-term.
PC software support
OWH80Q series support full communication interface, RS232, RS485, Ethernet, and also provide PC software for users to easily remote control the model.
Series/Parallel Operation Enabled - One Unit, Multiple Applications
The OWH80Q Series features flexible series and parallel operation modes, providing versatile power supply configurations within a single compact unit - ideal for a wide range of laboratory and industrial applications.
The fanless model (-F series) combines ultra-quiet operation with industry-leading power density, delivering up to 1000W and 40A without the need for cooling fans. This makes it exceptionally suitable for noise-sensitive environments such as research labs, automated test systems, and audio/video production facilities.
