Market’s Widest Selection of Programmable Electronic Loads
The PLA programmable electronic load is available in a wide selection of voltage and current ratings.  The voltage ratings can be as high as 1000V and as low as 60V, which operate at full current at .6V.  The current dissipation of these units can be as high as 1500Amps standard, but will reach much higher levels when units are paralleled.  These programmable loads are available in the following wattage ratings:  800W, 1.5kW, 2kW, 2.5kW, 3kW, 4kW, 5kW, and 7.5kW.  Higher wattage systems of 100kW+ are available upon request.

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.

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 LPL 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.

User Friendly Controls
The PLA’s new front panel design makes electronic test equipment easy to use and understand.  The knobs and buttons are organized in a manner that gets the customer up and running in minutes.  Most commonly performed operations can be accomplished in a few keystrokes.

RS-232 and GPIB IEEE-488 Standard
All PLA series air-cooled loads series air-cooled loads come with both RS-232 and GPIB IEEE-488 as standard features.  Both connectors are provided on the rear of the unit. Instructions for configuring are in the manual.

Ethernet and USB (optional)
The PLA programmable electronic load is also available with optional Ethernet and USB interfaces. This option is field upgradeable by the end user with minimal effort.

Oscillation Protection
The PLA series provides three levels of oscillation protection and can compensate for extended wire lengths.  AMREL suggests a minimal amount of cabling and other in-line components that introduce inductance. However, the oscillation protection can be set to slow down the load and improve performance.  This will save the electronic load from failing due to very fast spikes in voltage and current caused by inductance in the input wiring.

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