Solid State Relay Firing Boards
Zero-cross, instantaneous and configurable firing boards, designed to support voltages from 25V until 1200V, all our serie triggers 2 thyristors in antiparallel (W1C), which allows to obtain great advantages in the connection of loads. Furthermore, every board has a state control LED indiction.
Its devices are modular, using two or three modules/cards, it is possible to make three-phase applications (W3.2C and W3C).
Features SSR Firing Boards:
It is intended to be used in applications where high reliability is needed. This card is configurable to trigger SCR’s with pulse trains synchronized with mains voltage, or in permanent mode. It can be configured to start at zero crossing or random phase.
Control signal can be a logic level referred to card reference (high input impedance) or floating optocoupled input (low input impedance). Built-in power supply is feed directly from the mains, either 230 VAC or 400 VAC, 50/60 Hz.
The main zero-crossing advantage is decrease the surge current through the load during the first conduction cycle and helps reduce the level of conducted emissions placed on the AC mains. That occurs because the switching of the relay from a non-conducting to a conducting state occurs when the AC mains voltage reaches the zero-crossing point of the sine-wave.
Instantaneous solid-state relays turn on immediately after the application of the control signal. The output of the relay immediately begins to conduct load current as opposite to a zero-crossing relay.
