LD SERIES Key Features LD400 & LD400P COMPACT ELECTRONIC DC LOADS The LD series features electronic loads which are suitable for testing and characterising a wide variety of dc power sources. They can be used to investigate the behavior of many different types of power source such as PFCs, batteries and solar cells, as well as electronic power supply units.

LD SERIES Capabilities * * * TRANSIENT GENERATOR AND VARIABLE SLEW HIGH RESOLUTION SETTING/MEASUREMENT SETTING MEMORIES The LD series incorporates a full variable frequency, variable duty cycle transient generator. Switching between the two preset levels can be done at any frequency between 0.01Hz and 10kHz. The transient generator can be used in all operating modes. The rate of change between levels (slew rate) is controllable over a wide range.
PAGE 4
LD SERIES Remote control ANALOG REMOTE CONTROL The LD series incorporates analog remote control for all modes of operation. When “external voltage” is selected the level becomes linearly proportional to the voltage applied to the remote control inputs on the rear panel. A waveform can be used as the control voltage allowing complex load conditions to be simulated using, for example, an arbitrary waveform generator, such as the Aim-TTi TGF3000 series or a true arbitrary generator from the TGA series.

MODEL LD400 & LD400PP LDH400P TRANSIENT CONTROL MODEL LD400 & LD400PP LDH400P PROTECTION Pulse Repetition Rate: TRANSIENT GENERATOR Adjustable from 0·01Hz (100 seconds) to 10kHz Pulse Duty Cycle: 1% to 99% (percentage of period at Level A) Setting Accuracy: ±1 % Excess Power: The slew rate control applies to all changes of level whether caused by manual selection, remote control or the transient generator. The level change is a linear slew between the two level settings.
