3B Series PROGRAMMABLE AC & DC LOADS

Model : 3B Series

Q'ty :

The 3B Series DC loads comprises a range of medium to high power AC and DC capable load systems with support for up to 300Vrms input voltages.

All loads share a common user interface. Packaged in a compact 19” 4U chassis, 3B Series loads support up to 1800 VA per chassis. For higher power requirements, 3B Series load cabinets consisting of one master and one or more slaves units support power levels from 2400 VA to 12.6 kVA. These integrated cabinet systems operate from a single user control panel or remote control interface.

The Adaptive Power 3B Series loads are intended for medium to high power AC or DC test and product development applications in a wide range of industries. The 3B Series models support voltages to 300Vrms and are well suited for testing AC Sources and DC/AC inverters. Their flexible V-I operating curves span range of voltage and current combinations at any given power level. All 3B Series models have a low range mode for enhanced accuracy and resolution at lower voltage and current levels, further increasing their effectiveness.

The 3B Series consists of a total of nine different models up to 12.6kVA providing a wide variation of possible voltage, current and power combinations. For higher power AC or DC requirements, multiple 3B cabinets can be paralleled as needed.

Load Versatility

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.
