IonizersCompact SSR with 10A to 25A load current rating
02 Apr 2007
In contrast to electromechanical relays, semiconductor relays require no moving parts. Normally a more or less complex input circuit utilises a light emitting diode to control a photosensitive element (solar cells or phototriacs).
Such optical isolation allows the input circuit to control the load switching thyristor, triac or MOSFET(s), depending on the type of semiconductor relay.
However, due to their design, PhotoMOS relays can switch DC or DC and AC loads, whereas solid state relays (SSR) are only suitable for AC loads. On the other hand, SSRs can handle load currents from several hundred milliamperes to 40A or even higher. Naturally for such high currents, power loss and component size play an important role when choosing the right solid state relay.
For this reason, Panasonic Electric Works has overhauled its product range to meet the demands of miniaturization. We now offer compact solid state relays over all load current ranges. A perfect example is the AQJ SSR: available for load current ratings of 10A, 15A and 25A, it needs only 40% of the mounting area required by conventional hockey puck SSRs. In addition, the plug-in terminals let you connect the AQJ relay instantly.
Why not see for yourself what advantages the AQJ relay offers? Please take a moment to review it and the other superior solid state relays Panasonic offers.
