More Product Information

  • Closed-case Calibration
    • With the eLoad line, there’s no longer a need to send your electronic load back to the factory for calibration or remove dozens of screws to reach a potentiometer. Simply follow the AMREL calibration routine from the front panel and you should be back up and running in a very short period of time (some electronic test equipment needed). This will virtually eliminate downtime and eradicate the annual cost associated with shipping your eLoad back to the factory for calibration.
  • Individual FET Protection
    • To ensure the reliability of the PLA Series, AMREL’s design includes individual FET protection. A programmable electronic load may contain many FETs in parallel, which can create a cascading failure if one of them was to short out. AMREL’s eLoad programmable electronic load design isolates failures so other components will not be affected or stressed, increasing the system’s level of protection against catastrophic failure. With individual FET protection, the MTTR is reduced and the electronic load quickly returns to full operation.
  • Ultra-low Voltage Operation
    • The PLA design allows the programmable electronic load to operate at voltage levels approaching .1V. They will typically dissipate full rated current below 1% of their maximum rated voltage. For example, a 60V unit designed to dissipate1500A will allow the user to operate at .6V and still dissipate the full amount.
