Product Description
Williams Sound 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.
