Circuit-Shield Voltage Relays provide a wide range of protective functions, including undervoltage protection of motors, overvoltage protection, and automatic bus transfer. Inherently high seismic and transient immunity allow the use of these relays in generating stations or substations where the performance of electro-mechanical or other types of static relays is marginal.
The type 27S relay is an accurate, self-powered relay for monitoring dc control power busses. It may be used to alarm an undervoltage condition, or to initiate transfer to an alternate supply.
