The FAS-115DG synchronous relay from DEIF Dan Control is an automatic synchronization device used for synchronizing generators with busbars, with voltage regulation and circuit breaker time compensation functions.

###Functional Features
1. * * Automatic synchronization function * *:
-FAS-115DG can automatically detect voltage difference, frequency difference, and phase angle difference. When these parameters are within the preset limit range, the generator switch will be automatically closed.
-Suitable for various prime movers, including slow reacting diesel engines and fast reacting gas turbines.
2. Voltage regulation and circuit breaker time compensation:
-Provide automatic voltage regulation function to ensure voltage matching between the generator and the busbar.
-Support circuit breaker time compensation to ensure the accuracy of synchronous operation.
3. * * LED status indication * *:
-Provide clear LED status indication, displaying synchronization signals, control status, and matching of voltage and frequency.
4. * * Installation method * *:
-Supports 35mm DIN rail installation or base installation, making it easy to integrate into existing systems.
5. * * Dynamic synchronization and protection function * *:
-Perform dynamic synchronization to ensure that the slip frequency is always positive and prevent reverse power situations.
-Equipped with special filters to avoid inaccurate synchronization pulses caused by harmonic distortion or noise.
6. * * Extended Features * *:
-Provide analog frequency output and analog voltage output, which can be used to control the frequency and voltage of DEIF load sharing units (such as LSU-112/113/114DG and LSU-122DG).
-Support phase sequence check function to ensure that the phase sequence of the generator is consistent with that of the busbar.
###Technical specifications
-Voltage Range: Suitable for generators and busbars of various voltage levels.
-* * Frequency range * *: Supports 40Hz to 60Hz.
-* * Control pulse width * *: Adjustable to adapt to different types of prime movers.
-Installation method: 35mm DIN rail or base installation.
-Weight: Approximately 0.750kg.
###Application scenarios
-Ship power system: used for synchronous operation of ship generators and busbars.
-Industrial generator set: Suitable for synchronous control of generators on industrial sites.
-* * Backup power system * *: Ensure the synchronous stability of the generator when connected to the grid.
FAS-115DG is an ideal choice for synchronous control of generator sets due to its automatic synchronization function, voltage regulation capability, and high reliability.
