Rigol Technologies Introduces Dual Channel Power Supply Modules for Testing Applications


Rigol Technologies, a leading global provider of test and measurement instruments and solutions unveils its new models of high-performance linear DC power supply products, DP813A and DP822A, to meet the market demand for low-ripple, high-current, linear power supplies.

The DP813A is a single channel dual-range power supply while the DP822A is a dual channel power supply. The new models provide a programmable linear power supply with high current, low ripple, and high precision for many industries and applications such as optical communication module testing, chip and integrated circuit testing, semiconductor testing, and industrial ATE testing.

The DP813A and DP822A are widely used in optical communications module testing, semiconductor testing, chip and integrated circuit testing, and industrial ATE testing, providing engineers with high power linear power supplies with high current and low ripple. Single and dual power supplies can be adapted to a wide range of customer applications.

Key features of power supply modules:

  • DP813A
    Total Power: 200 W
    One Output with Dual Range: 8 V, 20 A / 20 V, 10 A
  • DP822A
    Total Power: 180 W
    Two Outputs: 5 V, 16 A & 20 V, 5 A

Lower Ripple, Less Disturbance

The ripple noise and pure output of the DP813A and DP822A is less than 350 μVrms/2 mVpp (3 mVpp), which satisfies the rigorous criteria for low noise. The transient reaction time is less than 50 μs, which fulfills the demand for fast-changing voltage waveforms.

Sense Function, Voltage Drop Compensation

When the power supply outputs a large current, the voltage drop on the load leads will become non-negligible. To ensure that the load obtains an accurate voltage drop, the sense function compensates for the voltage drop caused by the load lead, so as to ensure that the set power output value is consistent with the voltage obtained by the load.

More Features, More Interfaces

The Timer list capability is standard on the both the DP813A and DP822A linear DC power supplies, allowing them to output preset voltage and current (up to 2048 groups). The Timer's number of output groups, as well as the output voltage, current, and timing duration for each group, can all be customized by the user. The LAN, USB Device, and RS232 hardware interfaces on the DP813A and DP822A linear DC power supplies (USB-GPIB optional) make each device more able to communicate with your chosen hardware system.
