One of the most common problems, which is one of the most common problems, an alternative power supply such as generator and UPS is activated and prevents the deactivation of electrical devices. Automatic transfer switches on the other hand, perceiving this situation in the event of a power outage, the transfer process between the two electrical power supply without any problems automatically and quickly performs, thus creating critical situations of the electrical cuts, data centers, production facilities, transportation systems, etc. It is an electromechanical switch and control element that prevents it from being energized.

Sigma Electric Automatic Transfer Turns and Transfer Applications can be performed between 2 or more power supply.

1) Between the generator-generator

4) In systems with 3 different sources,

Which Sigma automatic transfer switch should I choose the most suitable?

Sigma automatic transfer switches are produced in 3 different types for need:

SATS Series Automatic Insured Transfer Slock (32-63A): When your main power supply is interrupted, automatically transfers the load to your backup power supply within 2sn. When your main source of power comes back, it automatically transfers the load to your main power supply within 2sn. One of the main power supply entry, one at the entrance of the spare power supply, one of which is up to 63As up to 63A with automatic insurances with automatic insurances with a cutting capacity to protect your system against short circuits and overload currents.

MATS-Class Automatic Transfer Slow (100-3200a): When your main power supply is interrupted, it transfers the load to your backup power supply within 2sn. When your main source of power comes back, the load again transfers the load to your main source of power within 2sn. MATS types do not have any thermal magnetic protection duty as in SATS types, if MATS type automatic transfer switches are used, appropriate circuit breaker should also be used.
