Easy Operation

Fast Transient Response

LED display and shuttle Control, DSP Series has an easy
operation and date display, such as Voltage, Current and
When output current demand changes rapidly in a large
range, the output voltage will decrease or increase
significantly in a short period of time. This type of
current change sometimes affect the performance
of EUT or test results. Having transient response
time smaller than 4~12ms, DSP series can fast
regulate output voltage to set voltage and
minimize the effects to EUT.


High Output Voltage + Current = Different Applications

The DSP series has different output voltage ranges  from 40V to 1600V and different current up to 2000A  appled  for different industries and applications.


DSP series has a wide range of output voltage, suitable for different market applications. Models over 500V output voltage are suitable for renewable energy, EV, and lithium battery industries. When it comes to circuit breakers, contactors or fuses that require high voltage or current, models with 2000A or 1600V can meet the power requirements of this type of component testing. The 400V or 320V models can be applied to server-related applications, as the increased needs for high voltage DC in data centers.
