Controlador LED regulable MeanWell

Mean Well LDC-80 series LED driver is a 80W AC/DC dimmable LED driver featuring the constant power mode output. LDC-80 LED driver operates from 1 80~295VAC and output current can be adjusted between 700mA to 2100mA.

Thanks to the efficiency up to 90%, with the fanless design, the entire linear LED driver series is able to

operate for -25°C~+85C case temperature under free air convection. LDC-80 Mean Well LED driver is equipped with various function options, such as dimming methodologies, so as to provide the optimal design flexibility for LED lighting system.

Mechanical Specification

Dimming Operation

※ 3 in 1 dimming function(for B-Type)

●Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:

0~ 10VDC, or 10V PWM signal or resistance.

●Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.

●Dimming source current from power supply: 100μA(typ.)

Note:

1. Min. dimming level is about 8% and the output current is not defined when 0%< Iout<8%.

2. The output current could drop down to 0% when dimming input is about 0Vdc or 10V PWM signal with 0% duty cycle.

3. To ensure the dimming performance at low dimming level,output current must be over 80mA.

DALI Interface

◎PUSH dimming(primary side)

●The factory default dimming level is at 100%.

●Ilfthe push action lasts less than 0.05 sec, it will not lead to a change for the status of the driver.

●Up to 10 drivers can perform the PUSH dimming at the same time when tilzing one common push button.

●The maximum length of the cable from the push button to the last driver is 20 meters.

●The additive push button can be connected only between the LS terminal, as displayed in the diagram,

and AC/L (in brown or black); it will lead to short circuit if it is connected to AC/N,

◎DALIinterface(primary side)

●Apply DALI signal between DA+ and DA-

●DALI protocol comprises 16 groups and 64 addresses.

●First step is fixed at 8% of rated output power.

NOTE: DALI, Push dimming can not be used in the same time!(The factory setting defaults to DA)

TEMPERATURE COMPENSATION OPERATION

LDC-80 have the built-in temperature compensation function; by connecting a temperature sensor (NTC resistor) between the +NTC/-NTC terminal of LDC-80 and the detecting point on the lighting system or the surrounding environment, output current of LDC-80 could be correspondingly changed, based on the sensed temperature, to ensure the long life of LED.

◎LDC-80 can still be operated normally when the NTC resistor is not connected and the value of output current will be the current level selected

through the IADJ. pin

◎NTC reference:

Notes:

1. MEAN WELL does not offer the NTC resistor and all the data above are measured by using resistor.

2. If new brand of NTC resistor is applied,please check the temperature curve first.

◎Dimming function of the driver will be invalid when the "temperature compensation" function is in use.
