LD400 - DC Electronic Load - TTi

The LD400 is an inexpensive electronic load which is 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.

LD400 - DC Electronic Load - TTi

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.

150 W DC Electronic Load - B&K Precision

The 8540 DC electronic load is a very compact, economically priced instrument that is at home on both the bench and the production floor. Though this is an instrument in a small package, it can reliably test a 5 volt power supply to 30 amps and do it continuously.

150 W DC Electronic Load - B&K Precision

The load can operate in CC, CV or CR mode while voltage/current or resistance/power values are measured and displayed in real time, making it well suited to test a variety of DC power sources.
Features Include -

SL series Electronic Loads - Sorensen

A wide range of loads are available from 75-1800W with both DC and AC input in benchtop, modular and standalone form factors.
SL series Electronic Loads - Sorensen
The SLM family includes 11 models of fully programmable, single input AC or DC modular electronic loads. DC models are offered to test power supplies, battery chargers, battery discharge, power supply transient response and integration into ATE systems. AC models are ideal to test low power inverters.
SLM Family Electronic Loads
The DC models support operation in Constant Current, Constant Voltage, Constant Resistance or Constant Power mode as well as a short simulation. Engineers have ultimate control of current waveforms by using either the analog input or CC dynamic mode. An analog input (single input DC models) allows arbitrary current waveforms up to 20kHz with an external 0-10V signal........
