Descrizione del prodotto

The motor load monitor BH 9097 checks the active power consumption of electrical consumers. As the measuring principle is only single phase correct measurement of 3-phase load is only possible when all three phases have the same load which is normal with motors. Using DIP-switches the unit can be set up to act as under- and overload relay P1min / P2 max. or as overload relay with pre-warning P1 max. /P2 max. The settings of P1 and P2 are absolute values and calibrated in Watts adjustable via rotational switches. 2 LEDs show the state of the corresponding output relays. The unit can be configured to energise or to de-energise on fault. Every output relay is fitted with it´s own time delay tv. A start-up delay ta acts on both outputs.
