KS-LTE200 is a high‑performance industrial 4G router designed for reliable operation in demanding environments. Supporting 4G LTE Cat 4, it delivers downlink speeds of up to 150 Mbps and uplink speeds of up to 50 Mbps.
Built with a rugged metal housing, the router features DC 9–48V wide voltage input with reverse polarity protection, as well as built‑in surge and ESD protection on the PCB. These design elements allow the KS‑LTE200 to adapt easily to harsh industrial conditions while ensuring long‑term stable and reliable operation.
The router supports RS232/RS485 serial port device connectivity, enabling serial data to be transmitted to internet servers for real‑time data monitoring. It also includes an eSIM chip, along with 4G TDD/FDD and broadcast network access. With wired + 4G failover backup, the KS‑LTE200 keeps your network always alive.
For local connectivity, the device provides 802.11b/g/n Wi‑Fi with speeds up to 300 Mbps and a high‑gain antenna, covering up to 30 meters in open environments. It also includes 10/100 Mbps wired Ethernet ports and supports up to 20+ concurrent users.
For secure remote networking, the KS‑LTE200 supports PPTP, L2TP, and IPSEC VPNs, enabling rapid remote networking. Combined with virtual server functionality, it facilitates fast and secure data exchange.

Feature Category Specific Feature Description Cellular Connectivity 4G LTE Cat 4 (150 Mbps down / 50 Mbps up) Ideal for industrial IoT, remote monitoring, vending machines, ATMs, and backup WAN connections where high bandwidth is not critical but stable connectivity is required. Dual SIM & eSIM Support eSIM + external SIM card Allows remote carrier switching without physical SIM replacement. Enables cost optimization by selecting the best available network. Network Redundancy Wired + 4G failover backup Automatically switches to 4G when the wired connection fails. Ensures continuous operation for critical applications like security systems or remote equipment control. Multi‑Network Support 4G TDD/FDD + broadcast network Compatible with global LTE bands. Broadcast network support expands connectivity options, especially in specialized industrial or public safety scenarios. Power Design DC 9–48V wide voltage input Accepts a broad range of power sources, from 9V DC to 48V industrial power supplies. Simplifies deployment in vehicles, solar sites, and factory floors. Power Protection Reverse polarity protection Prevents damage if power wires are accidentally swapped. Essential for field installations where wiring errors are possible. Electrical Protection Built‑in surge & ESD protection on PCB Protects against voltage spikes from lightning or static discharge. Critical for outdoor, tower, or industrial environments with electrical noise. Enclosure Metal housing Provides better heat dissipation, physical durability, and electromagnetic interference (EMI) shielding compared to plastic enclosures. Suitable for dusty or high‑vibration locations. Serial Connectivity RS232 / RS485 support Connects to legacy industrial equipment (PLCs, sensors, meters, RTUs). Enables remote data acquisition and control over IP networks. Wi‑Fi (Local Access) 802.11b/g/n, up to 300 Mbps Sufficient for configuration, maintenance access, and connecting a small number of local devices (e.g., laptops, phones, or secondary controllers). Wi‑Fi Coverage High‑gain antenna, 30m in open area Provides coverage for a small warehouse, workshop. Not designed for large offices but adequate for industrial local access. Wired LAN 10/100 Mbps Ethernet ports Connects to local PLCs, IP cameras, or configuration laptops. Lower speed is acceptable for most industrial telemetry applications. User Capacity Up to 20 concurrent users Suitable for small sites like a remote pump station, kiosk, or construction trailer with multiple connected devices. VPN Support PPTP, L2TP, OpenVPN Allows secure connection to corporate or central networks, provides enterprise‑grade encryption for sensitive data transmission. Reliability Focus Long‑term stable operation in harsh environments The combination of wide voltage, protection circuits, metal housing, and industrial components makes this router suitable for outdoor cabinets, factory floors, vehicles, and remote telecom sites. -
