Ag201
The Ag201 module is an extremely versatile, low voltage DC input, constant current LED driver module. Its’ wealth of features are all delivered in a tiny package, with a maximum of flexibility. Selectable constant current output drive allows connection to a huge variety of market leading LEDs. In addition, the module’s SEPIC, Buck-Boost DC-DC converter topology means the input voltage can be either higher or lower than the string (output) voltage, allowing for ease of design with a wide range of DC input voltages and LEDs. Flexible and powerful dimming control is built in with both fully isolated DALI and analogue (0.5V-10V) dimming inputs available.
