OMPS-E220/2-ISO , 10KA, Isolated Network Power Supply 2-in-1 Lightning Protector (2-in-1 Surge Protector), Surveillance Camera Lightning Protector, High-efficiency Protection, Stable Transmission, Integrated Lightning Protection Solution
Product Description:
OMRDON Isolated Gigabit Network Power Combination Surge Protector is a high-performance lightning protection equipment that integrates power supply and network signal synchronization protection functions. Strictly follow the IEC and GB national standards design, suitable for all kinds of weak power systems, security monitoring, network communications and telecommunications equipment, can be in the lightning electromagnetic pulse (LEMP) frequent environment to provide reliable protection for the equipment, suitable for LPZ 1-2 zones and 2-3 zones of lightning protection application scenarios.
The product adopts “power + network” two-in-one integrated design, compact structure, easy installation, widely used in outdoor base stations, security cameras, network switches, industrial control systems and other lightning protection and signal integrity requirements of the higher scene.
Lightning surge transmission path along outdoor lines::
Functional Features::
- ✅ Fully protected, safe and secure
- Power protection:Adopting three-level composite balanced protection circuit, with differential mode and common mode full-mode protection capability, extremely low residual voltage (≤900V), through-current capability of up to 10kA, can effectively resist strong lightning strikes.
- Network Protection:Support 100Mbps transmission, with isolation filtering function (front and back stage physical isolation, isolation voltage 1500V), can suppress signal interference, improve transmission distance and stability.
- ✅ Intelligent indication, status at a glance
- The power port is equipped with an LED indicator, green light indicates normal operation, and off indicates the failure of the protection module, which is convenient for daily inspection and maintenance.
- ✅ Compact design for flexible installation
- Adopting aluminum alloy atomization shell, with good shielding and heat dissipation, supporting screw fixation or 35mm standard rail mounting, greatly saving installation space.
- ✅ No leakage flow, long life
- Protecting the line to ground without leakage current, stable performance, long service life, maintenance-free design to reduce operation and maintenance costs.
typical application::
- Outdoor Surveillance Camera, Network Dome
- Base station communications equipment, optical transceivers
- Industrial Ethernet switches, routers
- Building automation systems, security alarm hosts

Installation Precautions
1. Tandem access:The input (INPUT) is connected to the line and the output (OUTPUT) is connected to the protected device.
2. Grounding must be secure:PE wire must be connected to the lightning protection ground network or equipotential terminal, grounding resistance is recommended to be ≤4Ω, and the cross section of the grounding wire is ≥2.5mm².
3. Near-equipment installation:Install as close as possible to the protected equipment for better protection.
4. Regular inspections:It is recommended that inspections be carried out in conjunction with system maintenance intervals, and that lightning protectors be replaced if damaged.
