Feature presentation

Low noise level: <350uvrms / 2mvpp

Designed to provide low noise and power signal ripple, it is designed to meet user requirements.

Fast transient response time: < 50us

The response time of the power supply should not exceed 50uS. This is perfect for rapidly changing voltage waveforms.

Standard timer output

When the timer is on, the instrument outputs the set voltage and current (up to 2048 groups). The user can set the number of timer output groups and set the output voltage, current and time for each group.

Built-in voltage V / current A / power W measurement and waveform display

Real-time measurement and trend display of V / A / W parameter changes at the same time

Output analysis, monitoring, preset setting and other functions

The device has functions of output analysis, monitoring, preset setting, etc. for comprehensive monitoring analysis

Original 3.5-inch TFT display

The easy-to-use, intuitive and clear display makes the device more convenient to operate. The front of the power supply features a traditional numeric interface and instrument panel interface.
