STABILIZED THREE-PHASE VARIABLE AUTOTRANSFORMER VAT_R10 SERIES

STABILIZED THREE-PHASE VARIABLE autotransformer VAt_R10 series

• Closed type, motorized model
• Input: 400Vac+N 50/60Hz Stabilized Adjustable Output: 0-435Vac+N
• Output voltage accuracy ±1.5% f.s.

K-factor voltage variators are designed for all the experimentation and testing needs of technical offices, laboratories and industries. they are supplied to have a variable voltage from 0V to 250V with different rated currents. The R10 version includes the variable speed drive controlled by a control PLC that keeps the voltage set constantly within a range of ±1.5% f.s., thanks to an output feedback system. It is possible to adjust the output voltage via a 0:10Vdc analogue signal via a connector on the back of the device, or MODBUS-RTU protocol via USB connector. As standard, an input switch, an output protection automatic circuit breaker, input and output terminals on the back of the device, a digital voltmeter with reading of the phase and concatenated output voltage, current on each phase, are mounted. Available options: surge arrester, output sockets, adjustment by means of a multi-turn potentiometer on the front.
