Maxgeek UVR6 Generator Automatic Voltage Regulator AVR Voltage Stabilizer Board for Mecc Alte Alternator

Maxgeek UVR6 Generator Automatic Voltage Regulator AVR Voltage Stabilizer Board for Mecc Alte Alternator

Description:
The UVR6 type voltage regulator is an advanced design electronic regulator that ensures excellent performance of the alternators while they are running and during starting. The regulator is equipped with a complete protection system against operation conditions that could be dangerous for the machine. The UVR6 regulator is suitable for being used with all Mecc Alte alternators and is standard supply for power outputs above or equal to 85 KVA, both three-phase and single phase.

Specification:
Sensing voltage input: 220-480V AC
Voltage input: 50-280V AC
Frequency: 50-60Hz nominal
Voltage output: max. 63V DC at 220V AC input
Current: continuous 6A, intermittent 7A for 10secs

Supply:
The supply to the regulator can be from 170 to 270V AC between terminals + and 2 of the terminal board, with + and B not connected, or from 80 to 160V AC between terminals + and 2 but with + and B connected to each other. Supply can also be separate from the sensing and in this case should be insulated from it.

Sensing:
The regulator is equipped with three differential sensing inputs (terminals 1-2, 3-45-6 ), which measure up to three different machine voltages. In this way you can check the average voltage on one or three phases of your choice. The most common connections are the following:
a)Direct voltage adjustment of one of the phase windings, with the machine either star or delta connected.
b)Direct adjustment of the voltage of the three phase windings (also for 12 terminal machines) , with the machine either star or delta connected. In both cases ("a" and "b"), the passage of the machine connection from triangle to star does not need regulator connection modification.
c)Direct adjustment of the voltage to the terminals being used, with machine either star or delta connected.

Protections:
The UVR6 regulator is equipped with two protection systems, and when they intervene the following
LEDS light up
a)Delayed protection for overloads (yellow LED)
b)Low speed protection (red LED)
Both protections have an intervention threshold that can be adjusted using the respective potentiometer. The protections cause an output voltage decrease that reduces the excitation current of the machine, so reducing overheating of the exciter rotor.
The overload protection has a delay that lets the machine overload briefly, for electric motor starting or other needs.
The regulator also has a third LED (green) which when lit indicates that the regulator is working correctly. All these signals can be observed remotely using the S.P.D. 96/A type "REMOTE PROTECTION SIGNALLER" that is available upon request.

Fuse:
The UVR6 electronic regulator is equipped with a fuse, which protects the alternator from overheating in cases of regulator malfunction. The fuse can be replaced easily, but the new one must have the same characteristics as the one being replaced (250V-6.3A,quick acting.

Usage Field:
-The UVR6 can be used with all voltages from 80 to 480V AC at 50Hz.
-It can also function at 60Hz by bridging the "60Hz" terminals of the regulaton terminal board.
-The admissible calibration field corresponds to the one specified for Mecc Alte alternators.
