Polytron Devices Inc. has been a leading designer and supplier of standard and customizable DC-DC converters, switching power supplies and linear power modules for 45 years. Founded in 1969 by David Metzger, Polytron Devices pioneered the development of linear power supplies and shipped many of the first units. We also sell to other well-known power supply companies who private-label our products for sale and distribution. Early on, we offered just two product familieslinear AC-DC power supplies and 10-watt DC-DC converters. Our focus on customer support and attention to global technological trends have allowed us to grow exponentially, and we now manufacture and distribute more than 100 different series of AC/DC power supplies and DC/DC converters.
