Amrel-PROGRAMMABLE ELECTRONIC LOAD SPECIFICATIONS (Model:ZVL-L )

 ZVL SERIES OF ZERO-VOLT PROGRAMMABLE LOADS

AMREL’s ZVL Series of Zero-volt dc Electronic eLoads are specifically designed for single cell fuel cell testing, ultra-low voltage battery testing, and 0-volt load applications. The ZVL zero-volt load offers the industry’s highest current rating for “0-Volt” operation. Custom-tailored voltage and current ratings make ZVL zero-volt loads perfect for many diverse applications.   All this in a compact fully-integrated, rackmount-ready package!

Traditional dc Electronic Load Solutions have inherent limitations for testing single cell fuel cells and PV cells/modules. Electronic loads use power-dissipating components that require a minimum compliance voltage of 0.6Vdc ~ 1.5Vdc for operation. However, single cell fuel cell and PV cells often require the dc electronic load to operate at below 0.1Vdc.  To meet single cell fuel testing and PV cell testing requirements, most electronic loads require an external booster supply. Not the case with AMREL’s ZVL zero-volt loads, which are manufactured with built-in booster supplies. Choosing AMREL’s zero-volt load will substantially reduce the cost and space associated with external boosters.

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 ZVL 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, theMTTR is reduced and the electronic load quickly returns to full operation.

Customization
AMREL’s outstanding engineering team can provide customizations and modifications to any of the ZVL units.  AMREL’scustomizations  can range from a simple modification, such as a different front panel color, to a complete custom electro-mechanical design.
