220v 50w 700ma Dimmable Constant Current LED Driver Transformer Manufacturers
SMT-050CMT is a 50w led driver 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, 700mA, 850mA, 900mA, 1050mA, 1150mA & 1250mA,1300mA,1400mA, are easily switched by adjusting the built-in DIP switch. and was designed to work with leading edge TRIAC dimmers, such as Lutron, C-BUS, Clipsal etc..
Do all of these units have protection from thermal overload (excessive heat), voltage overload, short circuit, and power surge?
Answers: Yes, all of those units have the protection from thermal overload (excessive heat), voltage overload, short circuit, and power surge.
