Things to Consider

This dimmer is strictly for DC12V or DC24V systems. Do not connect to AC100V household outlets. Maximum load is 3A (36W at 12V, 72W at 24V). Exceeding this may damage the unit. Only works with PWM-dimmable LEDs. Non-dimmable LED drivers or bulbs may not function correctly. IP54 rating means it is splash-proof but not submersible. Avoid direct rain or hose-down exposure. ## FAQ
Q: Can I use this dimmer with AC100V household lights? A: No, it is designed exclusively for DC12V or DC24V systems. It cannot be used with AC mains voltage. Q: What is the maximum wattage I can connect? A: At 12V, up to 36W; at 24V, up to 72W. Do not exceed the 3A current rating. Q: Can I connect wires directly without the DC5521 connectors? A: Yes, the terminals are quick-connect type and accept bare wires. However, ensure the connection is secure and within the product's specifications.
