Solid State Relays and Devices
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.

50/60Hz Notch Filter
The EDR 82534 is a low cost, multi-notch (comb) reject filter for low frequency signal applications. A Power interference
or band stop filter is an important and needed sub-component to design and build medical recording systems where minute
bioelectric signals, on the order of millivolts to microvolts are measured.
