Intended use
The power consumption limiter OM-611 is used to automatically disconnect the power supply to a single-phase installation circuit when the set value of power consumed by the receivers in the relay measuring circuit is exceeded. Operation
The limiter is adapted to work with a current transformer, the primary circuit of which is connected to the measured circuit, and the output to the OM measuring terminals, which allows you to control circuits of any load capacity setting the actual relay activation threshold higher than 5A (IOM). The range of the measured current will depend on the transformer ratio, e.g. from 5A to 50A with a ratio of 10:1 for a 50/5A transformer. The current of measurement input 4-6 must not exceed 5A. green (U). When the current in the measured circuit is lower than the set IOM switching threshold, the contact will be closed (position 7-10). Exceeding the set threshold in the measured circuit is signaled by pulsating red LED I>. After the set time Tdelay the contact will open (position 7-12). The contact will close automatically after the set Treturn time. If the current value in the measured circuit is still higher than the set threshold, the contact will open again.
