Adaptive Power Systems


The 5P Series DC loads comprises a range of power DC load systems with support of 60V. Packaged in a compact 19” 4U chassis, 5P Series loads support up to 14400W.

Key features:

  • Power: Up to 14400W 
  • Voltage: 60V 
  • Current: up to 1000A 
  • Operating Modes: CC, CP, CR and CV 
  • Built-in Short Circuit Test 
  • Over Power and Current Protection Test Mode 
  • Static and Dynamic CC Modes 
  • Available Interface Options are USB, RS232, GPIB and LAN 
  • Synchronized Operation of Multiple Loads 
  • Parallel Operation for High Power Applications 
  • High-Speed 5 Digit Precision Metering Capability 


Load Versatility  

All APS 5 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.

Power Supply Testing

Elaborate testing of linear and switch mode AC/DC power supplies at high speeds is made possible by flexible ranging and wide V-I operating curves found in all 5 Series APS loads. This supports high throughput production test and burn-in of power supplies.

Power Supply Design

With built-in features like over current protection (OPC) test and over power protection (OPP) test and dynamic constant current waveform testing, new power supply 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

Time sequencing of specific discharge current levels as a function of battery voltage allows characterization and performance testing of various battery chemistries. The high current resolution and accuracy of the 5 Series load supports testing of both small and large batteries.
