Current Monitor Sense Points Figure 2. DLT Attached to Interposer Supplying Operational Power to the DLT with Header Pins The DLT is powered by an external power supply. It will operate with an input supply of 10 V18 Vdc. The typical Choosing the Load Range input needed would be a 12 V supply capable of supplying The dynamic load tool is equipped with two load range > 600 mA. The input power is attached to the DLT in the settings (High & Low) The high load range offers the ability upper left hand corner via TPWR3 & TPWR4 or via the to load more power (Typically ~55 W total) and has a current optional Molex Connector (Molex part 39-29-3046). monitor resolution of 5 mV/A. The low load range has a lower loading power ability (Typically ~12 W total), but has a higher current monitor resolution of 25 mV/A. The low load range setting allows for better accuracy when monitoring low load conditions. It is important to enable only one of the loading options at a time. If both options are enabled then both drive circuits will operate. This will not cause any damage to the DLT, however both banks will be producing loads and both load current sense lines would need to be monitored and their respective current representation would need to be summed in some manner. The two load ranges have separate load sense monitoring points. These are located just below the DLTs operation selector switches. Figure 6. Input Power Connection ATTENTION: Disabling the High or Low Load section does not fully disconnect them. There will still be a low leakage Connecting the Function Generator current from the disabled drive stage. A 50 coax cable with EZ Clips can be used to attach the function generator to the two pin connector on the DLT with two ways to drive it: 1. By using an arbitrary waveform generator. Use the Direct Drive two pin connector and select EXT drive. When using this drive option, the signal generator can be set to provide a drive signal that is a replica Figure 3.
