SEL713/714 Series Programmable DC Electronic Load

The new SEL7 series programmable DC electronic load is a new generation product designed by Saluki Technology. Incorporating high-performance chips, the SEL7 series delivers high speed and high accuracy with a resolution of 0.1mV and 0.01mA (basic accuracy is 0.03% and basic current rise speed is 2.5 A/μs).

SEL7 series have wide application from production lines for cell phone chargers, cell phone batteries, electronic vehicle batteries, switching power supplies, linear power supplies, and LED drivers, to research institute, automotive electronic, aeronautic and astronautic, maritime, solar cell and fuel cell etc. test and measurement applications.
