25 watt 500ma Constant Current LED Driver Electronic Circuit
SMT-015CTM is a constant current led driver circuit with multi-stage constant current output; allowing a single unit to be used for applications with potential for multiple current levels, such as project style lighting designs. The current levels,300mA, 350mA, 500mA, 550mA, 450mA, 500mA, 650mA, 700mA,900mA, are easily switched by adjusting the built-in DIP switch. Multi-current DIP Adjustment output,15W/25W/50W available.
If we found any defective products within warranty ,what Smarts should us do for the defective product ?
We give 3 years warranty for 220v dimmer. If clients use properly, hardly any of feedback from our clients about the led drivers can not work or damaged during warranty time..
We do not make up for new replacement if we find damage cames from inappropriate use of clients, But if confirm that damage cames from 220v dimmer itself, pls collect and keep all defective 220v dimmer. We promised to replace a new one.
