| LC1x25-DAHybrid dimming technique per channel Dimming range/ch Helvar hybrid dimming products combines both Constant Current Reduction (CCR) amplitude dimming and Pulse Width Modulation (PWM) dimming. CCR is a very efficient technique for dimming the light output, especially on higher range. On lower range, the hybrid dimming products implement high-frequency PWM dimming according to the table above. CONVERSION TABLE FOR OTHER TYPES OF MINIATURE CIRCUIT BREAKER Type C MCB's are strongly recommended to use with LED lighting. Please see more details in "MCB information” document in each...

The current setting values are adjusted according to the LEDset specification. The resistor value for each required output current can thus be calculated from the formula R...

Information and conformity -freedoiw m liqktunj LC1x25-DA LED driver is suited for built-in usage in Luminaires. In order to have safe and reliable LED driver operation, the LED luminaires wilt need to comply with the relevant standards and regulations (e.g. IEC/EN 60598-1). The LED luminaire shall be designed to adequately protect the LED driver from dust, moisture and pollution. The luminaire manufacturer is responsible for the correct choice and installation of the LED drivers according to the application and product datasheets. Operating conditions of the LED driver may never exceed the...
