Unit UDP3305S-E is a bench programmable DC power supply with four independent output channels and a combined maximum output power of 328 W. Channels 1 and 2 provide an adjustable range of 0–30 V at up to 5 A each, channel 3 offers 0–6 V at up to 3 A, and channel 4 supplies a fixed 5 V at 2 A. The supply features 10 mV voltage resolution and 1 mA current resolution and includes RS232, RS485, USB and LAN interfaces for remote control and integration into automated test systems.
Advantages
The Unit UDP3305S-E combines multiple independent channels in a single enclosure, enabling simultaneous powering of several circuits with different voltage and current requirements. High resolution for voltage and current settings supports precise adjustment during development and test procedures. Multiple communication interfaces (RS232, RS485, USB, LAN) allow flexible remote operation, data logging and integration with laboratory automation or production test setups. Built-in protections and independent channel control simplify safe testing workflows.
Suitable for
- Electronic development and prototyping where several voltage rails are required
- Functional testing of boards and modules with mixed voltage domains
- Laboratory measurements and educational electronics labs
- Integration into automated test benches and production test systems

How to use
Connect the supply to mains power and power on using the front-panel switch. Configure desired output voltages and current limits for each channel using the front-panel controls or via remote interfaces. When connecting devices-under-test, observe correct polarity and ensure that combined load does not exceed the total power budget. Use the current limit settings to protect sensitive circuits and monitor output values on the front panel or through the communication interfaces. For automated sequences, program control commands over USB, RS232, RS485 or LAN according to the instrument's command set.
Usage recommendations
To ensure reliable operation, allow adequate ventilation around the unit, avoid loading channels beyond their rated currents, and verify connections before applying power. For integration into automated systems, test remote-control scripts at low voltage/current first and log measurements to detect deviations early.
