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.

2nd pair
Bought these locally for my grand-daughter. She wore them ALL the time and wore them out. She was so excited when I was able to find another pair on Amazon. She was begging me to sew them back together.

Defected Item
I bought two pair of these slippers, one for each of my children. One of the slippers on the smaller pair is defected, but alas we are past the return period. I just hate that we spent a good amount of money for what should be a quality product and it is defected. I hate for her to continue to wear them and possibly injure her foot due to the way the shoe leans.

Size: 7-8 Toddler, Color: Moo-moo Cow
These are so cute and comfortable. My 3 yo can put them on himself and it is so cute that they light up. Fit as expected and are great quality. Even the dog hasn’t been able to tear them apart. Would buy more styles!

Great brand
Size: 7-8 Toddler, Color: Moo-moo Cow
I usually order from their web site but they were out of stock so I decided to check Amazon and there they were. They are cute. The baby keeps them on his feet. They look warm because they are well cushioned. The quality is good and it makes a great gift because they light up.
