EXTERNAL CONTROL
Basic Functionality:
The external control function allows the eLOAD’s maximum range (L/M/H) voltage, current, power and resistance to be
sca led from 0 to 10 Volts. The externa l volta ge signa l will control the eLOAD to opera te a t the corresponding
current/volta ge/resista nce/power. Plea se see the ta ble below for further deta ils.
Note:
AMREL
specifications guarantee a 0 - 10 V External Programming Voltage. If an application requires a positive
and negative voltage swing (V
AC
), the External Programming port can support up to 10 V
