Description

High-voltage range + 4-digit visibility for faster bench decisions.

30-Second Fit Check

0–100V, 0–3A, up to 300W.
4-digit display supports tighter readback checks.
Preset voltage/current + power display for quick validation.
Optional RS485/RS232/USB for basic rig integration.

What it is + Why it matters

Bench-friendly way to cover higher-voltage DUTs without custom supplies.
CV/CC supports controlled bring-up and current limiting.
Useful when you need to confirm voltage points quickly during debug.

Key Specs

Output: 0–100V, 0–3A (max 300W)
Accuracy called out: V ≤0.1%+5 digits; I ≤0.2%+10 digits
Ripple (100V class): ≤18mVrms / ≤18mArms

Integration & Controls

Rear comms are noted as control/read (not full programming) on this series.
Manual input-voltage switching option appears on the platform.

Best for / Not for

Best: instrumentation, HV modules, factory verification up to 100V.
Not: automated sequences (choose programmable P-series).

Typical Applications

High-voltage module testing
Industrial lab verification
Production test fixtures
Electronics troubleshooting

Selection Checklist

Confirm current stays within 3A at your target voltage.
Choose comms option if you’ll log or control output.
Use HV-safe leads and “set limit then enable.”

RFQ Quick Checklist: qty • delivery • V/I range • comms (Y/N) • fixture constraints.
Note: Final compliance and performance depend on end-product design and verification testing.
