MDPB-40C

The SZMID MDPB-40C is a medium-power mobile phone signal blocker designed to provide reliable interference across a range of mobile communication standards, including GSM, CDMA, AMPS, DCS, PHS, 3G (WCDMA, TD-SCDMA, CDMA2000), 4G, and 5G signals. With a coverage radius of 10-25 meters (approximately 50-300 square meters), the MDPB-40C ensures that mobile phones within the target area cannot make or receive calls, send texts, or use data services, while leaving other electronic equipment unaffected. Once outside the jamming range, mobile devices automatically regain functionality without causing harm to users.

The system is built to handle the continuous evolution of communication standards, offering customization options to meet specific customer needs, including support for 2.4G and 5.8G Wi-Fi signals. Each channel delivers 4W of power, and the total output is 40W, or 50W when additional channels for 5.8G Wi-Fi are included. The MDPB-40C utilizes imported power amplifiers and IC components, ensuring efficient and stable performance.

The device is powered by a 220V industrial-grade power supply, featuring a built-in high-gain directional antenna to minimize interference with surrounding signals outside the target area. Its cooling system includes a large aluminum alloy radiator and four built-in cooling fans, ensuring long-term stable operation in high-demand environments. The use of high-quality flame-retardant PC material provides excellent insulation, high-temperature resistance, and durability, ensuring the equipment remains functional even in harsh conditions.

The MDPB-40C is designed for use in a wide range of locations where mobile communication is restricted or needs to be controlled, such as meeting rooms, auditoriums, courts, libraries, examination halls, schools, cinemas, and theaters. It is also ideal for sensitive areas like gas stations, oil fields, and government, military, or public security facilities, where mobile devices could pose safety risks or compromise secure communications.

With a soft-start circuit, AC surge protection, and low operating temperature, the MDPB-40C ensures long service life and reliable performance. It is an essential tool for maintaining security and preventing unauthorized communication in controlled environments.
