The three-phase power supply monitoring SPC230 primarily serves to monitor AV networks (voltage supply to general lighting).
A maximum of. 3 phases which lead an alternation voltage from 230V against the neutral conductor are checked. The switching threshold for recognising a mains failure or a severe mains fluctuation lies at 85% of the nominal mains voltage (230V AC), i.e. at approx. 195V AC. For evaluation, two changeover contacts are used with a maximum rating of 2A at 30V DC or 230V AC. The shift-in occurs automatically. Enclosure for DIN-rail TS35. Dimensions: H=44mm, W=54mm, L=96mm
