IonizersThe AQH solid state relay - the Lilliputian for Gulliver-size loads!
30 May 2007
If a list of the most underestimated components existed, the electromechanical relay would certainly be at the top. Panasonic Electric Works' long tradition of producing, refining and revolutionizing electromechanical relays proves this.
Though semiconductor relays have not displaced the electromechanical relay, they do enhance Panasonic's range of switching devices so that our customers can effectively solve any relay application with which they are confronted.
For a long time, solid state relays (SSR) with a triac output most suitable for main network voltages were the most popular semiconductor relays. However, in the meantime, PhotoMOS relays have established themselves. Both solid state and PhotoMOS relays stand out because of their low switching power, high isolation voltage between input and output, a virtually unlimited number of switching operations and silent operation.
As with switching and carrying currents, any heat loss that occurs has to be dissipated via the component housing. Hence the component's switching capacity is almost directly reflected by its size. The AQH is eminently suitable for managing large loads in the most confined space. Enclosed in an 8-pin DIP package, it is available with an input / output isolation of 5000V as a non zero-cross or zero-cross switch and can cope with peak voltages of 600V at currents of 0.3 to 1.2A. Take a look - don't let Gulliver-size loads tie you down!
