Design Features
With extremely low noise, the product can satisfy your
demands for highly pure power.
Excellent line regulation rate and load regulation rate
ensure the output stability and safety.
When the timing output is enabled, the system will
congure the voltage, current, and the duration time
based on the preset timer parameters, so as to provide
varied voltage and/or current output for the load.
It supports storing and recalling state les and timer
les, and allows you to restore the instrument settings to
defaults.
You can clearly view the status of the instrument from its
intuitive user interface. The help information is displayed
in real time at the bottom of the interface, convenient for
you to operate.
You can set thresholds for OVP and OCP values. If
overvoltage or overcurrent occurs, the power supply
shuts down the output automatically, and then a prompt
message is displayed.
When multiple power supplies are in serial or parallel
connection, enabling the external trigger function can
realize the synchronous output for multiple power
supplies.
The transient response time is less than 50 μs. When the
transient change occurs to the load current, the output
voltage can be quickly restored to the set value, ensuring
the output quality.
