Blocks of protection of lamps "Granite": purpose, technical characteristics

The problem of frequent burnout of lamps is quite common in our time. Lamp manufacturers claim lamp operation for several thousand hours. But in fact, the lamp can burn out without having worked even a few hundred hours, or even less. If you often have to change the lamps, then you can use a special device that will ensure the continuous operation of any lamp. In this article, we will consider one of the most common devices - the lamp protection unit "Granite".

Purpose of protection blocks

What functions does this device perform? The lamp protection units have a unique system that ensures a smooth start of the lamp. That is, this device protects the lamp from inrush currents when it is turned on, which is the main reason for the burnout of the lamps, regardless of their type. In addition, Granit protection units provide reliable protection of lighting equipment from overvoltages in a household network. Therefore, when using these protection devices, the lamp life is increased by 5-7 times.

Protection blocks can be used for various types of lamps, ranging from ordinary incandescent lamps to LED lamps. To protect low-voltage lighting devices, the protection unit is connected to the output of the step-down transformer (power supply). If the power supply is electronic, then you need to purchase a protection unit "Granite" with the marking "T".

Technical characteristics of lamp protection blocks "Granite"

When choosing a lamp protection unit, several selection criteria must be considered. Lamp protection blocks, like any electrical device, are designed for certain nominal values ​​of load parameters and the mains supply. The rated operating voltage of this device is 175-265 V. The maximum voltage at the load is limited to a value of 230 V.

A wide range of operating temperatures - from -20 to +40 degrees, allows you to install these devices, both to protect lighting devices indoors, and to protect outdoor lighting.

Another criterion for choosing the necessary protection unit is its rated power. Granite protection blocks are produced, rated for power from 150 W to 3000 W.

How to connect the lamp protection unit "Granite"?

Connecting this device is quite simple. The unit is installed in a wire break that goes to the light switch. That is, the connection of the protection device is carried out in series with the lighting device. This device can be mounted directly in the installation box in which the light switch is installed.

To do this, disconnect the wire that supplies voltage to the switch, connect it to the protection unit. Then you need to take a small piece of wire and connect one end to the protective device, and the other directly to the light switch.

Before performing work on connecting the protection device, do not forget about safety measures - do not forget to de-energize the wiring line that powers this lighting device.

In conclusion, it should be noted that the use of lamp protection units will significantly save your family budget. Connecting a protection device to each lighting device in an apartment or house is a rather costly affair, but in the future these costs are offset by the long life of the lighting devices. By installing protection devices, you will forget what it means to change the lamp.
