Discovery USB Programmable Power Supply (DPS3340) Specifications
Triple-Output USB Programmable DC Power Supply
Specifications are Typical, unless otherwise noted, and valid under the following conditions:
- Ambient temperature of 25 °C
- 30 minutes of warm-up time
- Using the included auxiliary power supply
All channels are independently controllable with independent current and voltage settings.

Device isolated from network through external supply. Outputs share a common GND between them and with the host PCB USB connector.
All three supplies feature overcurrent protection through software-settable current limits that can be applied individually to each channel. Same-polarity aggressor protection and reverse voltage protection work up to ±15 V.
When the software-implemented tracking mode is active, Outputs 2 and 3 will track each other in absolute value by applying any voltage change made to one channel's setting to the other channel. E.g. if Output 1 is set to 12 V, then Output 2 will be automatically set to -12 V.
The DPS3340 requires a host computer running the WaveForms software connected via USB to operate.
