The Rigol DP822A is a high-quality programmable DC power supply with two output channels. The first channel offers a voltage range of 0-20V and a current range of 0-5A, while the second channel provides 0-5V and 0-16A, with a maximum power output of 180W. It features USB Host/Device, LAN, RS232, and Digital I/O interfaces and includes a 3.5″ TFT display for clear monitoring of voltage, current, and power measurements. The device comes with a 3-year warranty..
⚙️ Key Benefits (Cause → Effect)
Independent channels → separate specs per load → one box, fewer swaps.
Fine control → tighter setpoints → truer results in labs and lines.
Stored profiles (up to 100) → auto-run sequences → repetitive tests go hands-free.
🖥️ Control & Visibility
320×240 screen → volts/amps/watts/limits stay clear → faster checks, fewer mistakes.
Live signal curves → spikes and sags visible → set safe limits with confidence.
Output analysis → median/mode/average/variance → prove stability with numbers.
⏱️ Automation (Steps → Results)
Programmable timer → scheduled V/I changes → burn-in, ramp, and stress tests run repeatably.
Recall setups → identical runs tomorrow → comparable data with less effort.
🌐 Connectivity & Remote Control
USB, LAN, RS-232, Digital I/O → SCPI from your PC → script, log, and integrate easily.
Plays well with LabVIEW → drops into ATE rigs → higher throughput, fewer manual tweaks.
🔌 Synchronization & Safety
Digital I/O triggers → in/out sync with scopes, loads, fixtures → tighter timing, cleaner experiments.
Output monitoring → meet your condition → warn / beep / shut off → protect the DUT instantly.
🧪 Where It Fits (Use → Payoff)
Two-rail boards → matched supplies → cleaner bring-ups.
Sensors/MCUs → step loads and ramps → fewer fried parts, faster tuning.
Production checks → saved sequences → dependable pass/fail gates.
📺 Clearly Arranged Display
3.5″ TFT, 320×240 → volts/amps/watts/limits stay clear → faster checks, fewer mistakes.
🧭 Output Monitoring
Watch output state → hit your condition → warn / beep / shut off → protect the DUT instantly.
📈 Display Signal Curves
Live traces → see spikes and dips while you tweak limits → set safer thresholds with confidence.
⏱️ Programmable Timer
Store up to 100 steps → auto V/I changes at set intervals → repetitive tests run hands-free and repeatable.
📊 Output Analysis
Review recordings → groups, median, mode, average, deviations → prove stability with hard numbers.
🔗 Trigger Output
Rear digital I/O → trigger in/out → sync with scopes, loads, fixtures → tighter timing, cleaner experiments.
🌐 Remote Control Via SCPI / LabView
USB, LAN, optional GPIB → send commands, log data, automate → drop into ATE rigs without fuss.
