CONTROL SYSTEMS
Product Description:
The NT538 WS control unit can be supplied by 85 to 260 Vac-Vdc, 50/60 Hz irrespectively of polarity in Vdc (terminals 40-42). This is obtained thanks to the use of a tested power supply unit, newly designed and manufactured, that frees installers from worrying about the correct Vac and Vdc supply. The earthing cable must always be connected to terminal 41. When the control unit is powered directly by the secondary of the transformer to be protected, it can be burnt out by high intensity overvoltages. These problems occur if the main switch is closed and the transformer does not have the load (no load test). The above is much more evident when the 220 Vac voltage is taken directly from the bars of the secondary of the transformer and there is a fixed capacitor battery for power factor correction of the transformer itself.
