Principle of operation
The device consists of two parts:
electronic, monitoring the current voltage;
power, which disconnects the pakistan email list 2.5 million contact leads load when peak values are reached.
The electronic part uses a compactor or a microprocessor. The latter allows for smooth adjustment of the device’s response limits.
A distinctive feature of the relay is its response speed. The voltage threshold depends on the potentiometer settings. Unlike the stabilizer, the voltage at the input and output of the device does not differ. Protection is provided by disconnecting consumers when the indicators deviate from the standards.
As a result, consumers in the controlled
Circuit will be temporarily disconnected, but will not burn out.
Most voltage control relays have permissible operating limits from 100 to 400 volts. Therefore, for lightning protection, it is necessary to is this the end of seo? additionally install voltage limiters.
Voltage monitoring relay in the form of an extension cord
Installation and connection diagram
Devices in the form of an extension cord or a case with a plug and socket do not require any special actions for connection. It is enough to insert them into an electrical outlet and connect electrical appliances to the output.
Mounting a relay on a DIN rail is more fax list complicated. Before connecting a digital relay, you need to prepare the following materials and tools:
short wire; Voltage monitoring relay
pliers;
indicator;
screwdriver.
The connection diagram is simple: the relay is inserted into the break in the circuit running from the machine to the consumers. The connection order is as follows:
Turn off the input circuit breakers;
install the relay on the DIN rail;
using an indicator, find the phase wire on the machine;
disconnect the phase and neutral wires from the machine and connect them to the relay output;
connect the phase and neutral contacts of the relay to the corresponding outputs of the machine;
Voltage monitoring relay turn on the voltage and check the functionality of the device.
If the machine only breaks the phase, the neutral wire is connected to the corresponding contact strip in the electrical panel.
