All APS 3B Series Loads are equipped with a powerful microcontroller and user friendly controls to provide capabilities that cover a wide range of load applications. Precision metering of Voltage, Current, Power and Resistance is standard.
AC Power Source Testing (AC Mode)
Elaborate testing of linear and switch mode AC Sources, DC/AC inverters or Frequency changers is made possible by flexible ranging and wide V-I operating curves found in all 3B Series APS loads. This supports extensive production test and burn-in of AC power supplies.
AC Power Source Design (AC Mode)
With built-in features like over current protection (OPC) test and over power protection (OPP) test and Power and Crest Factor control and non-sinusoidal waveform testing, new AC power source designs can be thoroughly evaluated against design specifications. An analog input mode allows arbitrary current waveforms to be applied to a unit under test as well.
Battery Charge/Discharge Testing (DC Mode)
Using the DC load mode, specific discharge current levels can be set as a function of battery voltage. This allows characterization and performance testing of various battery chemistries. AC/DC supplies and converters can be tested in DC mode as well.
