All APS 3D Series Loads are equipped with a large high brightness Fluorescent display and functional keyboard. This makes these load very user-friendly. Built in modes and capabilities cover a wide range of special load applications. Enhanced precision metering of Voltage, Current, Power and Resistance compared to prior generation load models 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 3D Series APS loads. This supports extensive production test and burn-in of AC power supplies, UPS’s, PV inverters as well as fuse and breaker testing. Standard test modes for these types of tests are built-in the 3D load firmware so less programming and user involvement is required compared to traditional loads.
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.
AC-to-DC Converter and Power Supply Design & Test (DC Mode)
The 3D Series load to double duty as fully capable DC loads as well so you are not stuck with wrong type load when it comes to testing AC/DC power supplies or DC/DC converter testing. (Not suitable for testing below 40Vac).
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. Several AC/DC supplies and converters can be tested in DC mode as well. Special battery discharge protocols are built-in the load including SoC monitoring and timed discharges.
