Adaptive Power Systems

3B Series: PROGRAMMABLE AC & DC LOADS

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.


Key Features:

  • 1200VA or 1800VA per Chassis
  • Up to 12,600VA per Cabinet
  • Voltage Range, 300Vrms
  • Current Ranges up to 126A per cabinet
  • High-Speed 4  Digit Precision Metering Capability
  • Parallel Operation for High Power Applications
  • AC Current Monitor Output Signal
  • Operating Modes: Constant Current (CC), Linear Constant Current (LCC), Constant Resistance (CR) and Crest Factor (CF) control
  • Leading and Lagging Power Factor (PF)
  • Over Current Protection Test Mode
  • Over Power Protection Test Mode
  • Conventional and Linear CC Modes
  • RS232 and GPIB Interfaces


Applications:

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 cpnverters can be tested in DC mode as well.
