Comnet Industrial 75 W Gigabit Power over Ethernet midspan injector compatible with - CNGE1IPS75AC

Comnet CNGE1IPS75AC Gigabit PoE Midspan Injector

Overview

The Comnet CNGE1IPS75AC is an industrial-grade midspan PoE injector rated for 75W power delivery across Gigabit Ethernet runs. Deploy this where you need to retrofit existing cabling infrastructure with power—no switch replacement required—and you're operating in environments that swing from -40°C to +75°C. The CNGE1IPS75AC accepts 100-240 VAC input from standard wall power and delivers 50-57 VDC at the output, making it suitable for IP cameras, wireless access points, industrial sensors, and other networked edge devices that demand sustained real-world power in temperature-extreme or surge-prone sites.

Key Features

• 75W PoE Power Output: Delivers 75W across the Ethernet line—enough for high-drain cameras (thermal, PTZ, high-resolution models) plus secondary edge devices on the same run. No separate power supply to the camera required; one cable carries both data and power.
• IEEE 802.3at Compliance: Adheres to PoE+ standard, so compatibility with standard PoE-capable devices is guaranteed. Integrates seamlessly into installations where your devices already expect PoE input.
• Gigabit Ethernet (1000 Mbps): Full IEEE 802.3ab backbone—no bandwidth throttling. Critical if your edge devices stream video at HD or 4K resolution or require real-time telemetry back to a central VMS or analytics platform.
• 6 kV Surge Protection: Shields both data and power lines from transient overvoltage. In outdoor or industrial sites where lightning, switching surges, or utility faults are present, this protection avoids catastrophic device failure and unplanned downtime.
• Wide Operating Temperature (-40°C to +75°C): Designed for harsh environments—freezing loading docks, hot equipment rooms, outdoor utility enclosures. No derating or thermal shutdown concerns in cold-start or summer peak conditions. Storage range extends to -40°C to +80°C, so you can stock units in unheated warehouses.
• IP20 Enclosure / Wall Mount: Compact plastic housing rated IP20 (no dust ingress protection, but splash-resistant). Mounts directly to a wall or DIN rail, taking minimal rack footprint. Lightweight (<2 lb), so installation on existing infrastructure requires no structural reinforcement.

Integration & Compatibility

The CNGE1IPS75AC works as a drop-in midspan injector for any PoE-enabled surveillance camera, access control device, or industrial sensor that expects 802.3at power. Situate it between your existing non-PoE Ethernet switch (or a PoE switch running out of power budget) and the remote device. Input power comes from standard 100-240 VAC wall outlet or UPS; output flows across a single Ethernet cable to the endpoint. No VMS, operating system, or driver configuration needed—it is transparent to your network.

If your network core already supports PoE but you've exhausted port capacity or power budget, insert the CNGE1IPS75AC on secondary branches to extend coverage without upgrading infrastructure.

Environmental Durability & Reliability

Humidity tolerance of 10–90% non-condensing means the unit handles typical industrial environments (unheated warehouses, outdoor equipment sheds, humid coastal sites) without corrosion or component failure. The 6 kV surge rating protects against common electrical transients—utility switching, nearby lightning, or poorly grounded cable runs—reducing the likelihood of catastrophic power delivery failure downstream. In surveillance deployments where a single injector may feed critical entry cameras or perimeter monitoring, this reliability margin directly translates to reduced false alarms and fewer service calls.

Frequently Asked Questions

Q: Can the CNGE1IPS75AC power multiple devices on one Ethernet cable?

A: No. The CNGE1IPS75AC is a single-port midspan injector—it supplies PoE power to one Ethernet cable run and the device at the far end. If you need to power multiple cameras, use one injector per cable run or upgrade to a multi-port PoE switch.

Q: What input power does the CNGE1IPS75AC require?

A: Standard 100-240 VAC wall outlet. No special power conditioning or UPS required, though backup power is recommended for critical surveillance systems. Draw will depend on load; at full 75W output, current demand is modest for standard branch circuits.

Q: Is the CNGE1IPS75AC suitable for outdoor mounting?

A: Not directly. The IP20 rating provides splash resistance but no protection against direct rain, dust, or submersion. Mount it indoors near the cable entry point or inside a protective enclosure if outdoor installation is necessary. The wide temperature range supports the device operating in outdoor environments once sheltered.

Q: Does the CNGE1IPS75AC require configuration or management software?

A: No. It is a passive injector—plug in 100-240 VAC, connect the input Ethernet port to your network, connect the output port to your camera or endpoint, and it works immediately. No IP address, no login, no firmware updates.

Q: What is the warranty on the CNGE1IPS75AC?

A: Refer to the manufacturer warranty documentation or contact the supplier for specific duration and coverage terms.

Q: Can I daisy-chain multiple CNGE1IPS75AC units?

A: Not in series—one injector per cable run. Daisy-chaining power injectors will cause voltage conflicts and device damage. Install separate injectors on separate Ethernet runs if you need to power multiple endpoints.

Ted Perry

The CNGE1IPS75AC is a workhorse midspan injector for surveillance retrofits where budget or logistics prevents a full switch upgrade. I've deployed it across retail and industrial sites where existing non-PoE Ethernet infrastructure needed to support modern IP cameras. The 75W output covers almost any single camera deployment—thermal, PTZ, or high-resolution models—without oversubscribing your power budget, and the 6 kV surge rating earns its place in outdoor or electrically noisy environments.

Technical Highlights:

• 75W PoE Power Output: Handles high-drain cameras (thermal units, motorized PTZ, 4MP+ models) that would choke a standard 30W PoE injector. Real-world benefit: no undersizing surprises and room to add a secondary low-power device (sensor, access reader) on the same run without risking voltage sag.
• 6 kV Surge Protection on Data & Power Lines: In industrial sites or outdoor runs exposed to utility switching transients or nearby lightning, this protection avoids the $1000+ cost of replacing a bricked camera. Single point of failure protection is often overlooked in PoE designs.
• Operating Temperature -40°C to +75°C: No thermal derating or shutdown in cold warehouses or hot equipment rooms. I've seen injectors fail or throttle in extreme climates; the CNGE1IPS75AC specification removes that variable from the engineering equation.

Deployment Considerations:

• Single-port design means one injector per camera run—plan your rack or wall space accordingly if you're scaling to 10+ endpoints. Multi-port PoE switches often offer better density if you have budget flexibility.
• IP20 enclosure is splash-resistant but not rainproof—do not mount this on an exterior wall or in a wet location. Keep it indoors near the cable entry point and protect it from condensation in humid environments.

The CNGE1IPS75AC is the right call for retrofit installations where your existing Ethernet backbone is solid but PoE wasn't designed in. Typical scenario: older office or warehouse with Cat5e/Cat6 runs already in place, new HD cameras going in, and a switch replacement is either cost-prohibitive or scheduling doesn't allow downtime. This injector solves that problem without cutting new cable.
