Series 2220 and 2230 Multi-Channel Programmable DC Power Supplies are ideal for testing a wide range of devices, circuit boards, modules, and products that require multiple power sources cost-effectively.
Series 2200 supplies provide two channels, each capable of outputting up to 30V and up to 1.5A. Series 2230 supplies include two 30V/1.5A channels plus a 6V channel with up to 5A output for powering digital circuits. The Model 2231A-30-3’s two channels can supply up to 30V at 3A each; the third channel can provide up to 5V at 3A.
Series 2230 power supplies provide up to 375 W of power in a compact 2 U high, half-rack wide enclosure. The 2230-30-6 offers up to 6 A from two channels; the 2230-60-3 offers up to 60 V from two channels. Adjustable, independent, and isolated channels can test two single voltage devices or a multiple voltage device with one power supply. Combine 30 V channels in series to increase voltage up to 60 V, or connect two or three channels in parallel to output as much as 15 A using the 2230-30-6.
| Key Features |
| Dual and triple output models with two 30V/1.5A (45W) channels and a 6V/5A (30W) channel on the triple output supply |
| All channels are independently controlled and have isolated outputs for maximum flexibility |
| All channels have remote sensing to ensure that programmed voltage is accurately applied to the load |
| Two 30V channels can be combined either in series to double output voltage or in parallel to double output current |
| 0.03% basic voltage output accuracy and 0.1% current accuracy ensure quality test data |
| Low noise, linear regulation with <3mVpp ripple and noise |
| Voltage and current outputs for all channels are displayed simultaneously for easy observation of each output state |
| Keypad entry allows fast, precise entry of output values |
| USB interface standard on all versions for remote control; “G” versions include USB and GPIB interfaces |

| All channels have isolated outputs | Allows providing power to circuits that are optically isolated or transformer-isolated from each other and have different reference points. |
| All channels are independently controlled | Supports powering up a circuit with multiple voltage levels (such as a digital circuit) that must be turned on in a specified time sequence. |
| All channels have remote sensing | Ensures that programmed voltage is accurately applied to the load. |
| Two 30V channels can be combined either in seriesor in parallel | Allows doubling output voltage or current. |
| Low noise, linear regulation | Ensures the level of power applied to the DUT’s load terminals is accurate. |
| Voltage and current outputs for all channels are displayed simultaneously | Allows easy observation of each output state. |
| Front panel numerical keypad entry | Simplifies fast, precise entry of output values. |
| Store frequently used configurations in any of 30 setup memory locations | Saves times when repeating tests. |
| Per-channel output timer | Turns off any output after a predetermined test time. |
