Product Description

The innovative technology has precious technology, with maintenance-free performance for a variety of long-term application, site isolation transformer, electronically balanced / unbalanced inputs and unbalanced outputs, inputs and outputs are equipped with radio frequency filters, as well as the hard-line interrupt bypass of power turning off and 2 seconds power-delay, enabling engineers to ensure the compatibility of various installation. Balanced input and output are for low noise operation; and the elimination of AC noise chassis / signal ground lift function.
