STEROSTAB T\u00a0THREE-PHASE 400V 50\/60 HZ<\/em><\/strong><\/p>\n

<\/div>\n

IREM AVRs are designed to deliver the declared power permanently (24\/7) under the worst operating conditions, i.e. at full load, at minimum input voltage and max input current and at the declared ambient temperature.<\/p>\n

3PH AUTOMATIC VOLTAGE STABILISERS\u00a0T MODELS<\/strong><\/p>\n

The voltage regulator of T series consists of a three phase variable auto transformer, a three phase series transformer, a low inertia servo driven motor and an electronic control circuit.<\/h3>\n

The control circuit makes out the average of the voltage values on the three output phases, and makes a constant comparison between this average value and a perfectly steady reference signal. If the difference between the average value and the reference voltage overcomes the limits preset by the AVR precision, a error signal is given out.<\/p>\n

This signal, which can be positive or negative depending on the voltage (if it is lower or higher than the nominal one), is amplified and operates the servo driven motor of the variable auto transformer which gives the additive or subtractive voltage necessary to bring the output voltage within the preset stabilisation limits.<\/p>\n

The regulation of the output voltage is true RMS, therefore the voltage regulator is unaffected by possible harmonic distortion present on the supplying line. This type of voltage regulator is suitable for well-balanced input lines and a maximum load unbalance among the phases of 50%.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
