EMRI 3TX20 automatic voltage regulator

This Voltage regulator 3TX20 is an original product of EMRI. It is an extremely robust voltage regulator, static exciter for excitation current up to 20 Amps at low field resistance slip ring machines or low rpm machines. The power input is separate from the measuring and can handle different items. Voltage regulator 3TX20 is designed for use in brushless generators and can be used as a cost effective universal replacement for a great variety original manufacturers AVR’s.The AVR can be used for parallel operation with other generators that also control voltage droopby means of Quadrature Droop Compensation (QDC).Parallel operation is possible with an additional droop CT.Installation, maintenance and adjustment don’t require special application software.The AVR is protected from the environment by a PUR coating.The sensing range of this AVR is suiteble for 160..250, 250..400, 315..510 Volt. The max rating of the AVR supply is 30..480 Vac and 50-60Hz. This voltage regulator can handle a maximal output current of 20A continuously with a maximum of 25A for 10sec and 30A for 1sec.
