New air-cooled electronic loads from Safety Power feature industry’s smallest footprint
Industrial and programmable power supply specialist, Safety Power Group, has introduced a new range of air-cooled programmable DC electronic loads that offer the industry’s smallest footprint to save valuable rack space in automatic test equipment (ATE) applications.
The new PLA series of air-cooled DC electronic eLoads features the highest power density and current rating along with the broadest selection of high voltage models on the market. Offering current ratings from 800W up to 250kW, the PLA series can also be custom-tailored to meets users’ exact application requirements.

Besides their ultra-compact air-cooled footprint, PLA eLoads are “Zero” stackable to save even more rack space while maximum return on investment (RoI) is ensured via closed case calibration without the need for units to be sent back to the factory or third party lab for calibration.

Additional exceptional features and benefits include ultra-low voltage operation at thousands of Amps, individual FET protection to isolate power stage failures, redundant over-temperature and over-power protection and fast response – 50 s independently programmable rise/fall time.

Safety Power’s PLA series offers voltage ratings from 60 to 1000V which operate at full current at 0.6V. The current dissipation of these loads can be as high at 1500A standard but will reach much higher levels when units are connected in parallel. The PLA series is available in 800W and 1.5, 2, 2.5, 3, 4, 5 and 7.5kW ratings as standard with higher wattage systems of 100kW and above available to special order.

The front panel design of the PLA series eLoads makes them easy to set up, use and understand. Buttons and knobs are organised in a manner that gets customers up and running in minutes and most commonly performed operations can be accomplished in a few keystrokes.

All PLA series air-cooled loads feature both RS-232 and GPIB IEEE-488 as standard with connectors for both on the rear panel. Ethernet and USB interfaces are available as options that are field-installable by the end-user with minimal effort.

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

PLA air-cooled electronic loads are ideal for use in a wide range of applications including battery, energy storage, ultra capacitor testing and validation, DC power supply and battery charger validation and testing, fuel cell durability, lifetime and performance characterisation, single cell and short stack fuel cell characterisation, EIS/impedance measurement, defence/aerospace and avionics ATE, electronics and power sources testing, thin-film, single and polysilicone PV design validation and testing, power supply, power electronic components validation and testing, industrial applications, generator/alternator, UPS/battery banks, datacentre backup power and automotive power electronics and components, lab/benchtop applications for R&D, testing and QC engineers, DC distribution and DC-DC converters and universities and national research labs.
