Can full-band signal jammers be installed in prisons, and are they DC powered?

With the advancement of social science and technology, information digitization has become an inevitable trend. As a symbol of the digital age, mobile phones have become an indispensable tool in people’s daily life and work. However, in certain specific places, such as prisons, mobile phones are strictly prohibited for safety and information leakage. For this reason, people have developed full-band signal jammers that can effectively block mobile phone signals and prevent mobile phones from connecting to base stations. However, the power supply problem, especially in places such as prisons, is a challenge.

Usually, prison environments use low-power full-band signal jammers, with an RF transmission power of about 2-3W per band and a total RF transmission power of about 30W for the entire device. The overall power consumption of these jammers is between 120W and 200W. The signal jammer itself is equipped with a switching power supply or a power adapter that can convert AC 220V to DC 5V or 12V to power the device.

There are a large number of signal jammers in prisons, and centralized control of power supply becomes necessary. The simplest way is to concentrate the power supply of all signal jammers in each building on an AC power line. However, prisons generally use DC power supply. Can DC power supply be used on existing lines to reduce the cost of switching power supply and line layout?

But this method is not advisable for the following reasons. First of all, the power consumption of each full-band cell phone jammer is not small. When using AC 220V power supply, the line current is close to 1A. When multiple signal jammers are connected in parallel on one line, the total current gradually increases. If DC power supply is used, the current consumed by a single full-band signal jammer can reach 10-20A. When multiple signal jammers are connected in parallel on a DC power supply line, the total current can reach hundreds of amperes, which does not meet the circuit usage specifications.

Therefore, it is recommended not to change the power supply mode of the full-band signal jammer to DC power supply on the existing line, but to equip it with a dedicated AC 220V power supply, and use centralized control to open and close to ensure the normal operation of the signal jammer without causing damage to the circuit or unnecessary risks.

In summary, the full-band signal jammer has become an essential equipment to ensure security and information confidentiality. When using it, its power supply mode should be carefully considered to ensure normal operation and safety and stability of the circuit.
