OVERVIEW

  • HT8XXX load is a precision programmable DC electronic load controlled by a high-performance microprocessor. It uses a 3.5-inch TFT true-color LCD display with a Chinese and English menu.
  • Offers 4 basic working modes (CC/CV/CR/CW) and 10 functional modes.
  • With comprehensive protection, over-heat protection, over-current protection, over-power protection, over-voltage protection, and loop oscillation protection. HT8XXX series  E-load supports RS232, LAN, USB and analog interfaces to fit your versatile solution and testing needs.

4 basic working modes CC/CV/CR/CW and 11 functional modes multiple extended function modes:

  • Short test function
  • DYNA dynamic test function
  • OCP over current protection mode
  • BATT battery mode
  • EFFT load effect mode
  • SWEEP dynamic frequency conversion scanning function
  • TIMING _me measurement function
  • OVP over-voltage protection mode
  • AUTO mode
  • LIST function
  • LED (HP8151 has no LED mode)

FEATURES

  • 500kHz high-speed voltage, current sampling rate
  • High-precision voltage and current measurement
  • Fast loop response speed and current slew rate Programmable single step up to 10μS
  • Equipped with remote four-wire compensation
