Q144-ZSB Synchronous indicator with parallel pulse output typeDetailed product description：

1. Purpose:
The Q144-ZB synchronous indicator with parallel pulse output is used for detecting and indicating the connection of multiple units to the grid in various power plant systems. It can also issue a simultaneous operation command when the frequency difference is less than a certain set value and before the difference reaches zero, in order to achieve automatic grid connection.
This product uses light-emitting diodes as indicator components, which have the characteristics of being eye-catching, sensitive, and free of mechanical wear compared to mechanical synchronous indicators. The product has frequency difference locking setting and parallel command lead time setting functions, suitable for use in various multi unit power stations.
