HLS-2D Metal Loss Test Driver


Developed to work in conjunction with the Loopworks Measure R1 or Ampetronic FSM, the HLS-2D Metal Loss Test Driver is a loop driver with a preset output level to give consistent test results as part of a quick and simple site assessment system.The HLS-2D comes with a 12V power supply but can also be used with a suitable 2V battery. It uses efficient class D current drive technology to reduce power consumption and heat output.

It is the only truly portable loop test driver that is capable of generating test signals to the IEC60118-4 Standard.The 4mm banana output sockets (included) allow simple connection to test cables and a 3.5mm single input cable completes the kit.

Williams AV is proud to offer Ampetronic Loop products in the United States and Canada. To purchase Ampetronic loop products in other countries, please visit https://www.ampetronic.com/
