Product Overview

The LD400 series inexpensive Electronic Load suitable for testing and characterising a wide variety of dc power sources. It can be used to investigate the behaviour of many different types of power source such as batteries and solar cells, as well as electronic power supply units. Its wide voltage/current range, multiple operating modes and built-in transient generator give it the versatility to offer test solutions from the design laboratory through to the component test area. The LD400P adds full bus remote control via USB, RS-232, GPIB and LAN (Ethernet) interfaces. The LD400 can operate at voltages below 500mV for currents up to 10A. At higher currents the fixed minimum resistance (typically better than 25mW) gradually raises the minimum operating voltage, but it remains below 1 volt up to 40 amps and below 2V up to 80A. This low operating voltage allows it to be used for many low voltage applications for which other electronic loads are unsuitable.
  • Versatile solution for testing dc power sources
  • Constant current, resistance, conductance, voltage and power modes
  • High resolution and accuracy for level setting
  • Built-in transient generator with variable slew
  • Current monitor output for waveform viewing
  • Variable drop-out voltage for battery testing
  • High resolution backlit graphic LCD with soft key control
  • Analogue remote control of levels and TTL control of ON/OFF and transient switching
  • Front and rear input terminals (front terminals 30A maximum)
  • Full bus control via USB, RS232, GPIB and LXI compliant LAN interfaces (LD400P)
  • Low minimum operating voltage of <1V at 40A
