We manufacture the best and unique devices some for controlling DC and AC power and some for signal processing to enhance SNR. Among large varieties of SPST, SPDT, DPST relays you’ll find many devices to meet your specifications. From D1L-series (a low cost, medium speed SSRs) to D9F-series (super-high power) devices that ready for switching various powers and drive different kind of loads: AC and DC/AC power, video, flashlamp for SS-laser, DC and stepper motors, solenoids, thermocoolers, audio signal multiplexing, quartz, lamps, coils, plasma, etc.

There are several ways to solve the problem of contact bounce (that is, to “de-bounce” the input signal). Often the easiest way is to get a piece of equipment that is designed to accept “bouncy” input and EDR’s made Solid-State Relays are the solution.

Solid State Relays

We manufacture the best and unique modules some for controlling DC and AC power and some for signal processing to enhance SNR. Among large varieties of SPST, SPDT, DPST relays with MOSFET and IGBT on their output(s) you’ll find a relay to meet your specifications. From D1L-series (a low cost, medium speed SSRs) to D3F-series (moderate costs and high-speed SSRs) devices are ready to switch various signals and drive different kind of loads: AC and DC power, video, flashlamp for SS-laser, DC and stepper motors, solenoids, audio signal multiplexing, quartz, lamps, coils, plasma, etc.
