FAQ
TL;DR: Moovo MCI1 runs on 12 V; "The voltage is 12V." Use a properly sized 12 V supply, not 120 W if the drive label shows 250 W. [Elektroda, Samuraj, post #17238703]
Why it matters:** This FAQ helps DIY gate owners decide between repair, like replacing a burnt NTC/IC, or choosing a safe external 12 V PSU replacement.
Quick Facts
- Output voltage: 12 V DC for the MCI1 control unit. [Elektroda, Samuraj, post #17238703]
- Drive label observed as 12 V / 250 W; size replacements accordingly. [Elektroda, skoczo, post #17246119]
- Quoted price for original PSU: PLN 500 (user report). [Elektroda, skoczo, post #16933122]
- Controller IC identified on the board: IRS2153D. [Elektroda, Samuraj, post #17225111]
- External IP67 LED PSU worked ~1.5 years, then hung until power-cycled. [Elektroda, skoczo, post #19062710]
What are the correct power specs for a Moovo MCI1 gate controller?
Users reported a 12 V system with a 250 W designation on the drive. Size any replacement around 12 V and up to 250 W. This aligns your PSU with the controller and motor demands, reducing brownouts and fuse trips. [Elektroda, skoczo, post #17246119]
Can I use a 120 W LED power supply as a replacement?
If your drive label shows 12 V / 250 W, a 120 W unit is undersized. Underspec supplies overheat or shut down under load. Choose a 12 V PSU with headroom toward the observed 250 W figure to ensure stable starts and motion. [Elektroda, skoczo, post #17246119]
What typically burns on the MCI1 power board?
A damaged NTC thermistor is often visible. Also check the bridge rectifier, two transistors or regulators, and resistors around the controller IC area. Heat and surge stress concentrate here, causing repeated fuse blows. Inspect both PCB sides before powering again. [Elektroda, antek124, post #16933477]
Which PWM/driver IC does the board use?
The controller IC noted by a repairer is IRS2153D. Match this exact part when ordering replacements. Verify pinout and package before soldering, and examine nearby startup and timing components for collateral damage. [Elektroda, Samuraj, post #17225111]
What do the parts marked “27E” under the IC look like?
A user asked about two elements marked 27E beneath the IC and mentioned differently marked parts (2742) with measured values near 58 kΩ. Treat them as resistors in the IC network and verify values against your board. [Elektroda, Samuraj, post #17225111]
How do I quickly triage a blown MCI1 supply?
- Visually inspect and replace a cracked or charred NTC at the AC input.
- Test the bridge rectifier for shorts; then check two series pass devices or regulators.
- Measure resistors around the IC area and replace any heat-damaged parts.
Follow with an isolated, current-limited power-up. [Elektroda, antek124, post #16933477]
What voltage should I buy if I’m sourcing a third‑party PSU?
Use 12 V output. As one repairer put it, “The voltage is 12V.” Confirm your drive’s wattage label to size current capacity appropriately before purchase. [Elektroda, Samuraj, post #17238703]
Will a DIN‑rail 120 W 12 V unit fit inside the MCI1 housing?
One owner couldn’t fit any internal replacement and went external instead. Space is tight in the original enclosure. Plan for an external, sealed PSU if your chosen model exceeds the available footprint. [Elektroda, skoczo, post #17246119]
Is an external waterproof LED PSU a reliable long‑term fix?
It can work but watch for latch‑ups. An IP67 12 V external supply ran ~1.5 years, then hung until disconnected for 15 minutes. Heat, duty cycle, and environment affect longevity. Consider higher‑quality models if going external. [Elektroda, skoczo, post #19062710]
What did users ultimately switch to when tired of repairs?
One user replaced the Moovo drive with a FAAC 740. They reported better range and connectivity within two weeks of use. Brand swaps can cut troubleshooting time when repeated PSU faults appear. [Elektroda, skoczo, post #19062710]
What is an NTC thermistor and why does it burn?
An NTC thermistor limits inrush current at power‑on. It runs hot during surges and can crack or burn after stress. In this case, a visibly damaged NTC was identified near other primary‑side parts. Replace it before further testing. [Elektroda, antek124, post #16933477]
How much does an original Moovo MCI1 power supply cost to replace?
A user reported PLN 500 for an original PSU. That cost drove consideration of third‑party supplies or a full drive replacement. Compare total repair costs with new operator kits before deciding. [Elektroda, skoczo, post #16933122]
Should I prioritize fixing the transformer or the electronics?
If the transformer is good, board repair remains cost‑effective. Focus on the input stage and control IC region first, then re‑evaluate. A working transformer lowers parts cost and complexity. [Elektroda, Samuraj, post #17239012]
What’s the safest way to size current for a 12 V replacement?
Size to the observed 250 W label when present. For 12 V, that implies around 20–21 A peak capacity to avoid shutdowns. Add headroom for startup surges and environmental heat. [Elektroda, skoczo, post #17246119]
