TTi – Thurlby Thandar Instruments

The LD400 is an inexpensive 400 watt electronic load which is suitable for testing and characterising a wide variety of dc power sources.

LD400 – DC Electronic Load – TTi

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.

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 25milliOhms) gradually raises the minimum operating voltage, but it remains below 1 volt up to 40 amps and below 2 volts up to 80 amps.

BOP high speed power operational amplifiers

BOP are high speed power operational amplifiers that can be used to provide dynamically agile voltage for test and simulation. They are not general purpose power supplies. By the nature of the bipolar high speed design, they do not have any energy-storage noise discriminating output capacitors.
