VAT-N – CLOSED TYPE THREE PHASE VARIABLE TRANSFORMERS CONTINUOUS REGULATION 0:435VAC FROM 4A TO 160A
THREE PHASE VARIABLE TRANSFORMERS CONTINUOUS REGULATION 0:435VAC FROM 4A TO 160A
It allows you to set the desired voltage manually via knob or handwheel, or automatically via servomotor (on request) in the adjustment range determined according to the customer’s request.
The variator, which is contained therein, is formed by making a single enameled copper winding on a toroidal core, with a rotating roller which creates a safe and permanent contact, free of friction.
The variac supplies the load with the regulated voltage
- METAL CABINET WITH DISSIPATION SLOTS AND NATURAL VENTILATION, IP21, RAL7032
- INPUT CIRCUIT BREAKER
- MAINS PRESENCE INDICATOR LAMPS
- OUTPUT CIRCUIT BREAKER
- Multi-function meter with voltage-current reading display on the three phases.
- WHEELS FOR TRANSFER
- Wire clamps on the front for inlet and outlet up to 25A – connection bolts on the back side for higher ratings
MOTORIZED VOLTAGE REGULATION
The version equipped with motorization replaces the regulation performed via knob or steering wheel, with a motor powered by direct voltage. To perform the voltage regulation, use the two up / down buttons.
MOTORIZED REGULATION WITH R10 REMOTE CONTROL
The version with R10 regulation allows you to use either a panel control (potentiometer) or a remote signal, analog or digital.
A switch is provided on the front panel for selecting the remote or local mode. The output can be regulated by sending a 0:10Vdc analog signal to the dedicated terminal, or via modbus-tcp using the RJ45 connector provided on the product. When choosing this option, there are no up or down buttons, but a potentiometer.
