UNI‑T UTP 3000 Series
The UNI‑T UTP 3000 Series linear DC power supplies combine precision, versatility, and professional performance in a compact benchtop form.
Key Features:
-
Three independent channels: two programmable up to 32 V/3–5 A (model‑dependent) plus a fixed 6 V channel ideal for logic circuits or fans.
-
Tracking functionality allows parallel or series operation—double voltage or combined current outputs—adjustable via channel‑1 controls only.
-
Exceptional precision: 10 mV/1 mA resolution, <0.01% +3 mV voltage regulation, and <0.2% +3 mA current resolution.
-
Heat-managed design: built-in temperature-controlled fan and overload protection ensure long-term reliability.
-
High output ratings: UTP3303‑II at 3 A with 207 W total; UTP3305‑II at 5 A with 335 W total output power.
-
Quad-digit LCD provides clear voltage and current readouts per channel.
This series is perfect for electronics development, lab testing, maker spaces, and educational environments, where clean, stable power is essential.
🛠 Technical Specifications
| Model | Channels | Max Output | Total Power | Resolution | |
|---|---|---|---|---|---|
| UTP3303‑II | 2× (0–32 V, 0–3 A) + fixed 6 V | 207 W | 10 mV / 1 mA | <0.01% + 3 mV / <0.2% + 3 mA | |
| UTP3305‑II | 2× (0–32 V, 0–5 A) + fixed 6 V | 335 W | 10 mV / 1 mA | <0.01% + 3 mV / <0.2% + 3 mA |
⚠️ Precautions & Safety Tips
-
Ensure airflow around the fan vents to maintain cooling efficiency.
-
Use tracking modes carefully: series doubles voltage, while parallel doubles current—both controlled via CH1.
-
Always observe channel current limits to prevent overheating.
-
Keep unit grounded and avoid input transients exceeding spec.
-
Turn off unused channels to extend lifespan.
