    • Very handy
Works as intended. I use it to switch my Walmart humidifier on/off during daytime/nighttime hours. Havent had any sort of safety issue, but maybe that's because I'm only using a small humidifier. I keep it turned on for 18 hours out of the day and then my UIS Controller turns it off. I really enjoy this plug because it saved me from having to spend extra money on a UIS humidifier! ... show more

    • Be sure you’re not pulling more than 15amp
AC infinity has always had quality product, but sometimes they fall a bit short. This one works but has its limitations as far as what it can control. ACs always blow the unit and it’s useless. But it’s perfect for a small portable ceramic heater. It doesn’t deal with brightness so it’s only for on/off items. It’s sleek and small and just what the doctor ordered for those units that don’t necessarily connect to the AC ecosystem. Solid buy, if you know what you’re using it for! ... show more

    • How to use the UIS Adapter safe (the only way)
⚠️ IMPORTANT SAFETY WARNING for AC Infinity Controller Users Regarding the UIS™ Control Plug Adapter ⚠️ Subject: Potential Risk Using the UIS™ Control Plug Adapter Directly with High-Power Appliances (ACs, Dehumidifiers, Heaters) Hey fellow AC Infinity users, This is a heads-up regarding the AC Infinity UIS™ Control Plug Adapter. While incredibly useful for integrating non-UIS devices, there's a potential safety risk if you use it directly to switch high-power appliances, especially those with motors or compressors like portable air conditioners, dehumidifiers, or larger heaters. The Problem: High Inrush Current: Appliances with motors (like ACs) draw a significantly higher current for a brief moment when they start up (this is called "inrush current"). Adapter Limitations: The UIS adapter, essentially a smart relay in a plug format, may not be designed to consistently handle these high inrush currents or the continuous high load of these powerful devices. Potential Risks: Directly connecting these high-load devices to the UIS adapter could lead to: Adapter Failure/Burnout: The adapter's internal components could overheat and fail prematurely. Controller Damage: A failing adapter could potentially damage the connected AC Infinity Controller port. Fire Hazard: Overheating electrical components always carry a risk of fire. The SAFER Solution without burning your house down: Use a Contactor and Circuit Breaker! To safely control your high-power appliance using the AC Infinity system, you should use the UIS adapter only to control a contactor (a heavy-duty electrical relay). The contactor will handle the actual switching of the high power load. You also MUST include a dedicated circuit breaker for proper protection. How it Works: The AC Infinity Controller tells the UIS Adapter to turn ON or OFF. The UIS Adapter sends a small control signal (likely 120V AC) to the contactor's coil (A1/A2 terminals). This small signal energizes the contactor's coil, causing it to close its main power contacts (L1/T1, L2/T2, etc.). The high power for your appliance flows from your wall outlet, through the dedicated circuit breaker, through the contactor's main contacts, and finally to a dedicated outlet where your appliance is plugged in. When the UIS adapter turns OFF, the contactor coil de-energizes, its main contacts open, and the power to your appliance is cut. This setup isolates your sensitive controller and UIS adapter from the damaging high power and inrush current. What You Need (Typical US Components (im from austria, i dont know exactly) - ALWAYS verify for your specific appliance!): Contactor: Load Rating: Must be rated for your appliance's voltage (likely 120V AC, but check!) AND amperage (check your appliance's nameplate - e.g., 15A, 20A). Choose a contactor rated at least slightly higher than your appliance's max current draw. Pole Configuration: For a standard US 120V appliance (with a regular NEMA 5-15P plug), a 2-pole contactor is ideal (switches both the hot and neutral wires). Coil Voltage: CRITICAL! The contactor's coil voltage MUST MATCH the output voltage of the UIS adapter. This is almost certainly 120V AC for the US market UIS adapter. Using the wrong coil voltage will destroy the contactor or it won't work. Look for "Coil: 120V AC" or similar on the contactor specs. Example Search Term: "2 pole 20 amp contactor 120v coil DIN rail mount" Circuit Breaker (MCB - Miniature Circuit Breaker): Rating: Must match the circuit protection required for your appliance and wiring (commonly 15A or 20A for standard 120V circuits). Check your appliance's requirements. Use a 1-pole breaker for 120V (switching the hot wire). Voltage: Must be rated for 120V AC (or higher). Mounting: DIN rail mount type. Example Search Term: "1 pole 15 amp DIN rail circuit breaker 120V" Enclosure: A DIN rail enclosure (plastic or metal electrical box) to safely house the contactor, circuit breaker, and outlet. Ensure it's large enough for wiring. Outlet: A DIN rail mountable electrical outlet matching your appliance's plug (likely a NEMA 5-15R for standard 120V/15A, or possibly NEMA 5-20R for 20A). Wiring: Use the correct wire gauge (AWG) for the circuit breaker rating (e.g., 14 AWG for 15A, 12 AWG for 20A). Use THHN or similar rated wire. Use appropriate colors (typically Black for Hot, White for Neutral, Green for Ground). Use smaller gauge wire (e.g., 18 AWG or 16 AWG) for the low-power connection between the UIS adapter output and the contactor coil (A1/A2). Miscellaneous: DIN rail, wire connectors (Wago, wire nuts), input power cord with plug, strain relief fittings. Simplified Wiring Flow: Wall Outlet Power (Input Cord) -> DIN Rail Circuit Breaker (Input) Circuit Breaker (Output) -> Contactor Load Terminals (e.g., L1) [Only Hot wire goes through 1-pole breaker] Wall Outlet Power (Input Cord) Neutral -> Contactor Load Terminals (e.g., L2) [Neutral bypasses 1-pole breaker] Contactor Load Output Terminals (e.g., T1, T2) -> DIN Rail Outlet (Hot, Neutral) Wall Outlet Power (Input Cord) Ground -> Continuously to DIN Rail Outlet Ground Terminal AND Enclosure Ground point. (Ground is NEVER switched or fused). UIS Adapter Output -> Contactor Coil Terminals (A1, A2) (Use a separate cord with a plug for the UIS adapter, connecting Hot/Neutral to A1/A2. Isolate the ground wire from this cord safely). Disclaimer & Final Warning: Working with mains voltage (120V/240V AC) is DANGEROUS and can cause serious injury or death if not done correctly. This information is for educational purposes only. If you are not 100% comfortable and knowledgeable about electrical wiring, PLEASE HIRE A QUALIFIED ELECTRICIAN. Always ensure power is completely OFF at the main panel before working. Follow all local electrical codes (NEC in the US). Double-check all connections before applying power. Don't risk your equipment or your safety! Use the contactor and breaker method for controlling high-power devices with your AC Infinity setup. Stay safe! ... show more

    • Works great but be careful- can be glitchy
I have several I use this to connect my fertigation/drip setup, low wattage heater, pump on home made clone, etc to the AC Infinity 69pro+ controller. Initially seemed like overkill when the existing mechanical timer works well but this is infinitely easier/better/quicker to set repeating cycles and make subsequent adjustments. Also it fits nicely on the power strip where other timers consume a lot of space. Not so good for variable schedules because AC Infinity’s controllers are particularly dumb with scheduling logic. I dislike that UIS connection comes out the side as can interfere with other items on power strip but not horrible if it happens to come with L shaped cable end- not all do. This week was tracking down anomalously high tent temperature and horrified to find that the cube I control light cycles with was stuck “on” for a couple days. Second time this has happened each time after changing timing via the controller screen. Easily dealt with by power cycling the cube and I’m thinking a power cycle after any parameter change might be a good idea but dropped rating a notch. Automation is wonderful but needs to be bulletproof! ... show more
