Electronic Design & Research Inc.

We manufacture varieties of AC, DC, AC/DC, NO & NC and TOTEM output Solid State Relays (SSR) to be used in many industrial, commercial and military applications. A SSR is a powerful relay/switch designed to outperform a mechanical type relay. Designed specially for high power motor controls, inverters, switching power supplies, choppers and high energy pulse circuits in the aerospaces, defense, transportation, industrial and medical industries. The AC/DC type SSRs, that are usable up to 2 MHz, found its way to control AC or DC power and sound, and the DC type SSRs can be added to a PLC to provide power to DC Motors. A SSR is an isolated fully hermetic power module which is idealy suited for driving various loads, where small size, high performance and high reliability are required. A wide range of package styles are available and there is no extra charge to make a any SSR to fit our D1N, D2N, D3N and D4N packages to meet your orders. Among other products, we make a super-low noise preamplifier, a voltage-controllable ideal high-pass filter, 50/60Hz digital filter, super-high resolution EKG, cardio-stimulator along with numerous other products and services have made EDR Inc. the valuable business partner and supplier it is today.
