Reliable Power and Protection for Your Network Devices
The Micro Instruments Guardian Series Gigabit PoE Injector is a robust and versatile solution for powering your PoE-enabled equipment while safeguarding it from electrical surges. This passive injector delivers both data and power over a single Ethernet cable, streamlining your installations and reducing cable clutter. Engineered for reliability, it features a high-power 70W PoE+ LAN transformer to ensure stable power delivery to your devices. Its integrated surge protection provides a critical defense against transient voltage, protecting your valuable network hardware from damage.
Unmatched Flexibility and Compatibility
What sets the Guardian Series injector apart is its exceptional user-configurability. With simple jumper settings, you can select between Mode B (power over 2 pairs) and Phantom power (power over 4 pairs) output, making it compatible with a wide range of devices. Furthermore, the output voltage polarity is also user-configurable on all four pairs, a unique feature that makes it ideal for equipment with reverse polarity requirements, such as Cambium Force 300 devices. This adaptability ensures that you have the right power configuration for your specific hardware needs.
Engineered for Durability and Peace of Mind
The Micro Instruments MI-POE-SP is built with high-quality components to ensure long-lasting performance. It accepts a wide DC input voltage from 12V to 60V, offering flexibility in your power source. For enhanced protection, the unit includes DC input polarity and over-voltage protection, along with a user-replaceable 2 Amp fuse. The data and power lines are further protected by 3-pole GAS discharge tubes, providing an additional layer of surge protection. An earth wire connection terminal allows for a safe discharge path for electrical surges, giving you complete peace of mind.
