The relay will be cheaper than the voltage stabilizer. In addition, these devices have the following advantages:
· the ability to control voltage throughout the entire electrical network;
· operability in a wide temperature seychelles email list 16461 contact leads range,
which allows the device to be used in almost any region and climate conditions;
· compact design, unlike large-sized voltage stabilizers. in the electrical panel, and also simplifies the installation process;
Aesthetic design, DIN rail compatible
· full automation of work.
Before connecting a voltage relay, you need to know about the following disadvantages of this equipment:
· the most effective protection of the who should use it? electrical network is achieved by installing several devices at once;
· if the relay serves the entire network, then in the event of significant voltage surges, all consumers will be de-energized at once.
Operating principle Advantages and disadvantages
Since the main function of the device is to control and regulate voltage, it consists of two main components – the electronic part and the power part.
The task of electronics is to monitor voltage indicators and, if they go beyond the permissible parameters, to transmit an order to the calling list power part to turn off the power. In other words, the electronic component is engaged in control functions, and the power part is engaged in executive functions.
Remember that the relay response limits can be determined by the manufacturer or set individually.
Technical specifications
To choose the right voltage relay, you should know the main parameters of the serviced electrical network. Depending on them, the technical characteristics of the device are determined, the main ones being:
Voltage range within which the device remains operational
· maximum power of the device; Advantages and disadvantages
· rated current at which the relay can function effectively.
Having information about the power grid in which the device will be used, as well as the approximate number of end consumers of current working simultaneously, you can select a relay with optimal electrical characteristics. It is important to be able to read and understand the marking of the device, which is usually indicated on the front side of the product. It contains the following information.
