Programmable DC Electronic Load ——150W-300W Series

Reliable programmable DC electronic load HT8151, 150W‑300W, high precision for power and battery testing.

DC Load Overview

The HT8151 150W‑300W programmable DC electronic load adopts a high-performance microprocessor, equipped with a 3.5-inch true-color TFT LCD and bilingual Chinese/English menu.
This precision programmable DC electronic load supports four core operation modes (CC/CV/CR/CW) plus 11 extended functional modes.
It integrates comprehensive protection functions: over-temperature, over-current, over-power, over-voltage and loop oscillation protection.
The HT8151 programmable DC electronic load comes with RS232, LAN, USB and analog interfaces for flexible integration into various test systems.

Load Technical

This programmable DC electronic load features 4 basic working modes (CC/CV/CR/CW) and 11 extended functional modes, including short circuit test, DYNA dynamic test, OCP, BATT battery mode, EFFT load effect, SWEEP frequency sweep, TIMING measurement, OVP, AUTO and LIST function. LED mode is not available for HT8151 model.
