Rigol DP831

Rs. 83721.00

The Rigol DP831 is a high-quality programmable DC power supply with three output channels: Output 1 provides 0-8 V / 5 A, Output 2 provides 0-30 V / 2 A, and Output 3 offers 0 to -30 V / 2 A, with a maximum power output of 160 W. The device includes a 3.5″ monochrome TFT display, programmable voltage curves, and the ability to store settings. It also comes with an NABL Calibration Certificate and a 3-year warranty. The HIRES-DP800 module (1mV/1mA high-resolution licenses) is included with the purchase, valid until 31.12.2025..

✨ Key Benefits (Cause → Effect)
Independent channels → separate specs per load → one supply, many jobs.
Real-time curves → spikes and sags visible → set limits with confidence.
Programmable timer → stored steps run automatically → perfect for repeats.

🧭 Control & Visibility
320×240 display → volts/amps/watts stay sharp → quick checks at a glance.
Tight setpoints → safer bring-ups → fewer fried parts.

🔌 Connectivity (Plug → Perform)
USB Host/Device, LAN, optional RS-232/GPIB → SCPI control → script runs, log data, slot into ATE.

📊 Analysis & Monitoring
Output monitoring → hit a condition → warn / beep / shut off → protect DUTs instantly.
Built-in stats → median, mode, average, variance, deviation → verify stability fast.

➕ Tracking & Sync
Tracking for dual 30 V rails → set one value → partner channel follows (even ±) → cleaner analog setups.
Rear Digital I/O → trigger in/out → sync with scopes, loads, fixtures.

🧪 Where It Fits (Use → Payoff)
Op-amp and analog bring-up → instant ± rails → stable tests.
Sensor/MCU boards → soft ramps, step loads → protect new silicon.
Production fixtures → repeatable profiles → reliable pass/fail data.

📺 Clearly Arranged Display
3.5″ monochrome TFT → 320×240 → volts/amps/watts/limits stay clear at a glance.

🧭 Output Monitoring
Watch output state → hit a condition → warn / beep / shut off → protect DUTs instantly.

📈 Display Signal Curves
Real-time traces → see spikes and dips → set current limits with confidence.

⏱️ Programmable Timer
Store up to 100 steps → auto V/I changes on schedule → repetitive tests run hands-free.

📊 Output Analysis
Built-in stats → median, mode, average, variance, deviation → verify stability fast.

🔗 Trigger I/O
Rear digital I/O → trigger in/out → sync with scopes, loads, fixtures for tighter control.

🌐 Remote Control (SCPI / LabVIEW)
USB, LAN, optional RS-232 → send commands, log data, automate easily → drop into LabVIEW rigs without fuss.
