More Product Information

LPL SERIES OF LOW-PROFILE PROGRAMMABLE ELECTRONIC LOADS (150W-800W)

In ATE System Applications, rack space is a highly coveted asset. Traditional modular loads require at least 3U (5.25”) of rack space, additional mainframe cost, and is limited in power rating, typically below 300W.

For years the test and measurement industry was in need of a portable, general-purpose dc electronic load. The available load solutions were either rackmount or multi-channel mainframe-based. The form factor aside, trim pots were the standard calibration method. Users in the Test and Measurement Industry demanded a load bank solution that was compact and portable, embedded with GPIB/RS-232, capable of bench-top closed-case calibration, offered dynamic operability such as profile simulation and could easily be calibrated on a bench without removing the cover.

FCL SERIES OF PROGRAMMABLE LOADS FOR FUEL CELL TESTING (200W-1.5kW)

AMREL’s Integrated Fuel Cell Load “FCL” Series is the ideal all-in-one solution that packages a booster supply for true “0-volt at high-current” operations. The FCL also has an embedded FRA for impedance measurement/EIS, and a full featured high-speed dynamic dc load in an ultra-compact 3U (5.25”) air-cooled package. AMREL’s FCL offers the industry’s highest current rating of 200Adc, as well as custom-tailored voltage, current and power ratings.

You will discover a wide range of options in AMREL’s FCL Series of fuel cell programmable loads.  If you can’t find what you need, FCL models are capable of being custom-tailored to meet your application requirements.

ZVL SERIES OF ZERO-VOLT PROGRAMMABLE DC ELECTRONIC LOADS (ZVL-E ETHERNET-BASED MODELS 200kW-1.5kW)

Like the ZVL-L models, AMREL’s ZVL “E” Zero-volt Ethernet-based dc electronic eLoad models have the industry’s highest current rating for “0-Volt” operation. In addition, they offer Ethernet and USB connectivity as well as power ratings up to 1.5kW. That’s a lot of power in a compact fully-integrated, rackmount-ready package.

AMREL’s ZVL “E” Zero-volt Ethernet-based dc electronic eLoads are specifically designed for single cell fuel cell testing, ultra-low voltage battery testing, and 0-volt load applications. Custom-tailored voltage, power & current ratings, optional impedance measurement, and 16-bit precision make ZVL “E” Zero-volt eLoads perfect for many diverse applications.

  • 3 sizes – 150, 300, & 600W @ 500V with advanced measurement capability built-in
  • Mix & match loads for maximum configuration flexibility
  • Up to 16 loads in a single, 8 3/4″ / 5U Model 4300 chassis
  • Front loaded & front connections
  • 3 voltage and 3 current ranges for improved accuracy
  • High-resolution waveform capture for analysis of dynamic transients
  • Isolated digital inputs & outputs for test fixture support
  • PC/LAN control with LabVIEW & IVI drivers

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.

BPL SERIES OF BENCH-TOP PROGRAMMABLE DC ELECTRONIC LOADS (400W-800W)

The BPL Bench-top eLoad strikes the perfect balance between value, features, and ROI. Built on dual current shunt architecture, the BPL provides accurate current readings for high-currents up to 200Adc and low-current readings down to the micro-amps.

AMREL’s BPL Series of "Bench-top" dc Electronic eLoads offers high-end performance, the industry’s highest power-density and current-rating, fast response time and unparalleled current measurement accuracy in a 3U ½ rack package.The BPL is a full-featured, powerful, ultra-compact, and user-friendly bench-top eLoad.

You will discover a wide range of options in AMREL’s BPL Series of "Bench-top" dc Electronic eLoads.  If you can’t find what you need, BPL models are capable of being custom-tailored to meet your application requirements.
