The Rigol DP712 is a high-quality programmable DC power supply with one output channel, offering a maximum voltage of +50 V, a maximum current of 3 A, and a total power output of 150 W. It features a user-friendly interface, a large TFT display, and advanced functions like programmable voltage curves, timing output, and overvoltage/overcurrent protection. The device is backed by a 3-year warranty..
🖥️ Display & Control (See → Act)
Large digits, clean layout → quicker checks → fewer mis-sets.
Front keys/knob → tap, adjust, confirm → smooth workflow.
⏱️ Timing Output (Set → Run)
Pick voltage, current, duration → timer drives the curve → complex test profiles run hands-free.
Save sequences → replay later → consistent, comparable data.
💾 Storage & Recall (Profile → Repeat)
Store setups → recall in one step → swap tasks without re-tuning.
Defaults restore → fast recovery after experiments.
🌐 Remote Control (Plug → Perform)
RS-232 + SCPI → automate steps, log data → cleaner reports, fewer manual errors.
Plays nice with fixtures → standardized runs across benches.
🔒 Protection & Thermal (Limits → Safety)
OVP/OCP thresholds → hit a limit → output shuts down, prompts action → DUT and supply stay safe.
Fan cooling → steady airflow → reliable operation 0 °C to 40 °C.
🧪 Where It Fits (Use → Payoff)
Board bring-up → soft ramps + limits → fewer fried parts.
Regulator tests → timed steps → honest transient behavior.
Teaching labs → simple UI + recalls → faster learning, safer benches.
🖥️ Clear, Intuitive Interface
Status stays visible → real-time help sits at the bottom → tap, adjust, confirm without guesswork.
🔒 Overvoltage & Overcurrent Protection
Set OVP/OCP thresholds → output crosses a limit → supply shuts down and prompts next steps → DUT and supply stay safe.
⏱️ Powerful Timing Output
Choose voltage, current, duration → timer runs the sequence → load sees the right profile at the right time.
🔗 Convenient Trigger Function
Use external trigger → multiple supplies fire in sync (series or parallel) → starts line up, data stays comparable.
💾 Easy File Storage
Save state and timer files → recall in one step → restore defaults or proven setups fast.
