Description

A 100V-class adjustable supply for labs and factories that need voltage range more than current.

30-Second Fit Check

Need up to 0–100V and 0–3A (max 300W).
Testing higher-voltage modules where a 30V supply won’t reach operating points.
Want CV/CC with preset setup and power display for quick verification.
Optional comms exist for read/control (options vary).

What it is + Why it matters

Higher-voltage range helps you validate converters, drivers, and HV subsystems without workarounds.
CC mode gives a controlled way to limit current when validating unfamiliar DUTs.
Power indication supports faster failure triage (is it drawing what you expect?).

Key Specs

Output: 0–100V, 0–3A
Max power: 300W
Ripple (100V class): ≤18mVrms / ≤18mArms
Accuracy called out: voltage ≤0.1%+2 digits; current ≤0.2%+10 digits

Integration & Controls

Front output ON/OFF, CV/CC indicators, and preset-style operation.
Optional rear interface: RS485/RS232/USB (options vary) for bench data logging/control in simple rigs.
Chassis size class: 280×130×165mm.

Best for / Not for

Best for: high-voltage adjustable DC needs up to 100V with modest current.
Not for: high-current low-voltage rails—choose 15V/20A models for that.

Typical Applications

High-voltage module testing (within ratings)
Instrumentation and industrial lab setups
Factory test stations needing adjustable 100V output
R&D validation for converters and drivers

Selection Checklist

Confirm your DUT won’t exceed 3A at the required voltage.
Define the measurement needs: do you require 4-digit display? If yes, consider the F-series 100V model.
If you need programmable sequences, select the programmable P-series 100V model.
Use safe HV practices: insulated leads, clear labeling, and controlled enable/disable steps.

RFQ Quick Checklist: qty • delivery target • required voltage range • max current • comms (Y/N) • fixture/safety constraints.
Note: Final compliance and performance depend on end-product design, wiring, and verification testing.
