PRI-51-1 product information
Example of application: the output relay is off in normal state. In case the target current level is reached, the relay switches on.
The relay PRI-51-1 can be used to protect against overflows energy from solar systems (GridFree) into the grid by disconnecting the micro-inverters when the consumption is lower then selected value.
The relay PRI-51-1 is easily adjusted by potentiometer in the range from 0.1 to 1 Amp (AC), so it is suitable for measuring of devices with power rating from to 23 W to 230 W. The measured current is only for AC (at a voltage of 230 VAC). For higher current ratings, the current relay PRI-32 should be used.
Example: The current value is set by the formula: power/voltage.
The building has permanent consumption 80 W and the relay will be installed on home wiring 230 V: 80/230 = 0.35. The current relay will be set to value 0.35.
Power supply AC 24 - 240 V or DC 24 V (galvanic separation from measured circuit)
Output contact: 1x changeover/SPDT 8 A, clamp connecting terminals
DIN rail mountable (single position)
