Rigol DP813(A) and DP822(A) DC Power Supplies

Rigol expands its DP800(A) family of DC power supplies with two new models

  • Rigol Technologies is expanding its DP800(A) series of DC power supplies with the DP813(A) and DP822(A) models, which can deliver 200W and 180W of power respectively.

 
The DP800(A) power supply series was launched in 2013. It includes four models that offer various optional features: Ethernet and RS232 interface, digital trigger I/O, a monitoring and analysis application, and a high-resolution mode that can be enabled later.

The new DP813(A) and DP822(A) models can deliver significantly higher current. The maximum current level increases from 10 A to 20 A for the DP813(A) power supply and to 16 A for the DP822(A) model.

The DP813(A) output channel can be used in two different ranges. The power supply can deliver up to 8 V/20 A and up to 20 V/10 A.

The DP822(A) power supply has two channels. The first can be adjusted up to 20 V/5 A and the second up to 5 V and 16 A.

Both models have a sense channel on the high current output to detect voltage drop across the test leads.

Rigol DP800(A) power supplies specifications

These power supplies (except the DP822(A)) can deliver current and voltage levels up to 10% higher than specified. For example, the DP832(A) can deliver 33 V and 3.3 V of current through its outputs 1 and 2. One of the two outputs of the DP822(A) can deliver up to 16.8 A.

All power supplies in the range can be used in constant current (CC) or constant voltage (CV) mode.

These power supplies have a noise level below 350 mVrms/3 mVpp. They offer high line and load regulation stability: <0.01% +2 mV/+250 µA.

The multi-channel power supplies have isolated channels. Two outputs can be connected in parallel or in series to increase the current or voltage. In addition, they are equipped with overvoltage or overcurrent protection (OVP)/(OCP).

A timer allows specific voltage or current profiles to be output. Rigol also offers free PC software for setting up the power supplies or recording the respective curves and saving them in a *.csv file.
