SZ Vodasafe VS-PL12 Professional Trolley Case High-Power Full-Band Signal Jammer
The VS-PL12 high power portable signal jammer is a heavy-duty signal control device independently developed by SZ Vodasafe, built based on core radio communication suppression and wideband scanning technology. It can completely cut off the wireless communication link between mobile terminals and base stations, forcing all nearby smartphones, tablets and wireless devices to show “no service”, “searching network” or disconnected Wi-Fi status. This unit supports 24-hour non-stop mains power operation and short-duration mobile battery operation, with flexible single-point deployment or distributed networking layout to fit signal isolation requirements of small, medium and large-area sites. Equipped with an integrated retractable pull rod and dual universal casters, the rugged security hard case enables free on-site transfer without opening the chassis for activation, perfectly matching temporary security, confidential meeting, emergency anti-interference and mobile law enforcement scenarios.
Core Functional Advantages
1) Full 12-Channel Comprehensive Signal Shielding
This machine adopts a 12 independent channel design to cover all mainstream global cellular and Wi-Fi frequency bands, including complete 2G/3G/4G/5G mobile signals as well as Wi-Fi 2.4G, 5.2G and 5.8G wireless network signals. Each channel operates independently without mutual interference, allowing targeted shielding of single or multiple signal types as required.
2)Ultra-High Total Output Power & Wide Coverage
The total module output power of VS-PL12 reaches 600W (antenna gain excluded). It adopts industrial-grade N-type connectors matched with omnidirectional fiberglass antennas, delivering a shielding radius ranging from 10 meters to 300 meters. The actual coverage distance fluctuates according to local base station signal strength, building obstructions and electromagnetic environment; open spaces with weak surrounding signals achieve the maximum isolation range.
3)Humanized Portable Trolley Integrated Design
The whole machine is wrapped in shock-resistant industrial security chassis with built-in telescopic pull handle and two silent universal wheels, supporting flexible dragging and transshipment for field tasks. Operators can launch shielding function directly without disassembling the case cover, greatly saving on-site setup time. All supporting antennas are stored in a dedicated carrying bag for neat transport and anti-loss management.
4)Dual Power Supply Modes for Flexible Scenarios
Two power supply schemes are available to adapt to fixed and mobile use cases:
Mains power mode: Supports AC220V 50/60Hz city power input, converts to DC24-28V working voltage for 24/7 uninterrupted long-term continuous operation, ideal for fixed confidential rooms, courtrooms and detention areas.
Built-in lithium battery mode: Equipped with DC24-28V 56Ah large-capacity industrial lithium battery, which can sustain stable shielding work for about 50 minutes without external power, suitable for temporary field deployment, mobile patrol and emergency response missions. The battery module features an LCD real-time display to show remaining charging and discharging capacity for convenient power status monitoring.
5)Modular Plug-and-Play Structure with Independent Channel Control
Inside the unit are 5 dual-channel independent power modules, each fitted with a dedicated built-in cooling fan. The pluggable module design simplifies post-sales maintenance and part replacement without professional disassembly tools. Every single channel is equipped with an independent adjustable power knob, enabling users to lower or shut down the output power of any single frequency band as needed. Corresponding LED indicator lights visually display each channel’s working state, while built-in isolators and VSWR standing wave protection circuits prevent module damage caused by antenna mismatching or short circuits to extend service life.
6)Heavy-Duty Efficient Heat Dissipation System
To handle long-hour high-power operation, VS-PL12 integrates high-efficiency aluminum alloy profile heat sinks plus 17 built-in high-speed cooling fans distributed inside the chassis. The layered heat dissipation structure rapidly exhausts internal heat, maintaining stable equipment performance within a wide working temperature range of -20°C to 50°C, and avoids power attenuation or automatic shutdown due to overheating during continuous operation.
7)Strict Factory Quality Assurance
Every VS-PL12 unit undergoes rigorous testing procedures before delivery, including multi-round spectrum analyzer calibration and extended load aging testing to verify stable power output and consistent shielding performance. The whole machine is covered by a 1-year official manufacturer warranty from SZ Vodasafe to eliminate after-sales concerns for bulk purchasers and security institutions.
