Discovery Power Supply (DPS3340) Specifications
Under Construction!
These specifications are valid following 
minutes of warm-up and are typical at °C unless otherwise noted.

Isolation Voltage
Device isolated from network through external supply. Outputs share a common GND between them and with the host PCB USB connector.
Protection Circuitry
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.
Tracking Mode
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.
Connectivity
The DPS3340 requires a host computer running the WaveForms software connected via USB to operate.
