How Alfa Gamma Regulators Work


 


Servo-motor controlled Alfa Gamma voltage regulators have input voltage limits between 160-250 V. The output voltage is 220 V and has a %2 tolerance in this voltage range.

Alfa Gamma regulators adjust the voltage fluctuations which may occur in mains with a speed of 50 V/ sec.Output voltage limit is 240 V and if this voltage is surpassed due to a lightning strike or disconnecting of the neutral line or any other reason, the output voltage will be cut. This is called high voltage protection. The high voltage protection circuit is not an option for our customers and we do not let our customers have Alfa Gamma voltage regulators without high voltage protection circuit and it is an integrated part of the electronic card. When the electricity goes off and goes on, it usually comes higher. Alfa Gamma regulators have the delay circuit that adjusts the fluctuated voltage before giving the voltage back to the output. Thus we ensure %100 protection.

In three-phase regulators each phase works individually. Regulators have input voltage limits between 280-430 V. Unlike single phase regulators, if the neutral line or the phase is disconnected. Alfa Gamma regulators will be shut down for protection. Additionally, since excessive voltage decreases are inconvenient in three phase regulators, we also do not let our customers have our regulators without low voltage protection circuit. Excessive voltage protection circuits are protected by the help of the circuit breaker. When one or two phases are exposed to excessive loads (loads emerged in operating motors), our regulator will shut down for protection.

Alfa Gamma regulator control cards are detachable, consequently replacing of the control card is quite simple. Output voltage and voltage protection limits can be adjusted. Output voltage can be watched by the voltmeter which is on the device. In our three phase regulators, each phase can be watched individually. In the system the fluctuations that may be occured by excessive feedback can be prevented by the pot.

Alfa Gamma regulators have by-pass switch for maintenance.
