## 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

## Power Supplies

All channels are independently controllable with independent current and voltage settings.

#### 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.

 Device to Computer Interface USB 2.0 Hi-Speed, Type B.

## Power Requirements

The DPS3340 requires an auxiliary power supply. A compatible power supply is included with the purchase of the DPS3340.
