• Electronic DC Load, 80V, 80A, 400W with analogue control interface only
• Versatile solution for testing dc power sources
• Constant current, resistance, conductance, voltage and power modes
• Wide voltage and current range, 0 to 80V and 0 to 80A
• 400 watts continuous dissipation at 28oC (360W at 40oC)

The LD400 is an inexpensive electronic load which is suitable for testing and characterizing a wide variety of dc power sources

Low Minimum Operating Voltage

This low operating voltage allows it to be used for many low voltage applications for which other electronic loads are unsuitable

600 Watts Intermittent Power

The LD400 can operate at power levels up to 600 watts for periods of up to 1 minute

LD400 Series: Electronic DC Loads – 80A, 80V, 400W

The LD400 is an inexpensive electronic load which is suitable for testing and characterizing 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 10 amps. 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 2 volts up to 80 amps. This low operating voltage allows it to be used for many low voltage applications for which other electronic loads are unsuitable.

The LD400 can operate at power levels up to 600 watts for periods of up to 1 minute. Short term loading can be sufficient for many testing applications and significantly extends the usefulness of the LD400.
