350ma constant current led driver circuit.

Demonstration circuit 762 is a 350ma 1w synchronous boost white led driver featuring the ltc3490 and a lumileds luxeon led. 73 5 x 35 x 23mm universal input r. This led constant current power supply has screw terminals on the input and output for easy connection. Mean well led power supply 16w 350ma dc driver16w 350ma non waterproof.

Screw terminals for easy connection suitable for powering led s requiring constant current supply dimensions. So if the resistor is 3 57 constant current will be 350ma. Use prima transformer driver and or ballast to comply with cul. Is the input voltage dc or ac.

Constant current led drivers maintain a fixed output current ma which is usually measures in milliamps ma or amps a and within a specified range of voltages. Click or call 802 728 6031. Designed for indoor application.

The input voltage range of the lt3490 is 1v to 3 4v. Shop ledsupply free shipping the lowest prices on the racd06 350 recom 350ma constant current led driver. Question 1 year ago answer upvote. 1 year ago.

These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the led system. Output 350ma 6 1 8w 3 36v. In the constant current led driver circuit you do state that in step 6 the input voltage varies from 3 volts right up to 60 volts. So if you want to connect one or more luxeon 1w leds which has a power consumption of 350ma the calculation should look like this.

Higher current ratings do make the led brighter but if not regulated the led will draw more current than it is rated for. 1 25 the constant reference voltage of the lm317 divided by 0 350 the leds power consumption makes 3 57. However the demo board operates with a 1 8v to 3 5v range. Fly leads 20awg 15cm for rapid connection.

All prima fixtures and lighting systems must not share circuit with any existing fluorescent fixtures. Mean well s ap constant current driver is a good example shown below. 18w 350ma constant current led driver. A constant current led power supply works by varying the voltage along an electronic circuit and thus allows the current to remain constant throughout the led system.

Lamps wired in series and total value of led vf should be under 48v. Compact lightweight in plastic case.
