UNI-T UTP3313TFL-II Linear DC Power Supply
Overview
The UNI-T UTP3313TFL-II is a 90W single-channel linear DC power supply delivering 0–30V at 0–3A per adjustable channel. The linear topology produces clean, low-ripple output suitable for powering sensitive analog circuits, precision measurement systems, and development prototypes where switching noise is unacceptable.
The UTP3000 series provides independent channel control with CV/CC operation, series/parallel channel combination modes, OVP/OCP protection, and USB connectivity with SCPI support for basic remote control and automated test integration.
Key Features
- 90W Linear Output (0–30V, 0–3A) — Clean, low-ripple DC power from a linear regulator topology.
- CV/CC Operation — Constant voltage and constant current modes with automatic crossover.
- OVP/OCP Protection — Configurable thresholds protect devices under test.
- Series/Parallel Modes — Combine channels for higher voltage or higher current output.
- USB Interface with SCPI — Remote control capability for basic automation.
- Compact Form Factor — Space-efficient design for crowded workbenches.
Applications
Bench Development
Clean linear output for analog circuit prototyping, sensor testing, and mixed-signal development. Independent channels power multiple circuit sections simultaneously.
Education
OVP/OCP protection prevents damage from student wiring errors. Simple controls and clear display make the UTP3313TFL-II straightforward for lab instruction.
Service & Repair
Reliable bench power for electronics repair work. CV/CC modes handle diverse powering requirements across different equipment types.
Production Test
SCPI over USB for basic automated test integration. Consistent linear output quality ensures repeatable results.
Frequently Asked Questions
What's the difference between the UTP3000 and UDP3000 series?
The UDP3000 series (UDP3303A/C, UDP3305C/S/S-E) adds a color display, higher resolution, more memory locations, and LAN connectivity alongside USB. The UTP3000 series provides the same linear topology and clean output at a lower price with USB-only connectivity.
What's included with the UTP3313TFL-II?
