What It Is + Why It Matters

High‑precision programmable DC electronic load for R&D labs, production testing, and education.
CV/CC/CP/CR regulation with fast transient response (<23 µs rise) enables accurate dynamic load simulation.
Integrated function generator and arbitrary waveform generator (up to 99 sequences) eliminate external signal sources.
Battery discharge test (static/dynamic) with Ah, Wh, and time counters for complete battery characterization.
MPPT tracking (4 modes) simulates solar inverter behavior for photovoltaic panel testing.
Galvanically isolated analog interface plus USB and Ethernet (ModBus RTU/SCPI) for flexible ATE integration.

Note: Always configure OVP/OCP/OPP thresholds before connecting a voltage source. The device is not protected against external overvoltage when unpowered.

Selection Checklist + RFQ

Confirm source voltage ≤ 80 V, current ≤ 45 A, sustained power ≤ 500 W (peak ≤600 W).
Select regulation mode (CV/CC/CP/CR) and set OVP/OCP/OPP thresholds to protect your source.
Choose remote interface: USB, Ethernet (ModBus/SCPI), or galvanically isolated analog (0–5V/10V).
If rack mounting, order the optional 2U mounting frame (10 400 111).
For battery or MPPT testing, ensure test parameters match the built‑in function capabilities.
Plan adequate ventilation: ≥30 cm free space behind the unit, unobstructed side air inlets.
