High Power Constant Current Source LKO DC 1000mA

Product No.: LKO1000 Weight: 0,0040 kg Print product data sheet: Availability:     DE - Shipping time: 1-3 business days EU - Shipping time: 2-5 business days 11,99 EUR incl. 19 % Tax  excl. Shipping costs    Low-Drop, Low-Cost High Power Constant Current Source for d.c. voltages up to 40 volts of a extreme compact design. Several High Power LEDs of the same type (respectively with identical current consumption) can be connected in series. An additional series resistor isn`t required. The circuit supplies the High Power LEDs with constant current and reliable protects the LEDs for voltage spikes. Please note that the LKO is a linear regulator, i.e. the voltage difference is transformed in heat. For this reason some combinations aren`t reasonable or possible. The sum of the voltages of all connected LEDs have to be at least 0.8 volts below the supply voltage. When the maximum allowed power dissipation of the technical datas is exceeded, the LKO will overheat and shutdown. The maximum power dissipation is calculated by the output voltage (sum of voltages of all connected LEDs) and the power according to the following formula: Power Dissipation = (Supply Voltage - Output Voltage) * Power Example: 6 white 1 Watt HighPower LEDs with 1000mA power (1A) and 3,7 volts forward voltage of 24 volts Power Dissipation = ( 24 volts - 22,2 volts) * 1A = 1,8 volts * 1A = 1,8 VA (watts) If the calculated power dissipation is over the additional value of the technical datas, then we recommend our Konlux LED Driver. The following table shows you a general view of the operating range. The number of the LEDs relates of the white LEDs with a forward voltage of 3.8 V. The table shows you the power dissipation of the particular supply voltage and the number of LEDs. Technical Specifications from Datasheet: Input: 4,5-40 volts DC (reverse polarity protection) Output: 1000 mA DC (short circuit proof) Power dissipation: 3 watts (6 watts cooled) Drop: 0,8 volts (Low Drop) Operating temperature: -40°C bis +85°C Measurement: (L x B x H) 23mm x 40mm x 4mm Weight: ca. 4 gram Shutdown-Pin for external control and dimmer Thermal protection Production of SMD technology The cooling plate on the back side is isolated from the circuit The connection-LED mustn`t connect with the negative pole of the supply voltage! Specific output currents in the range of 50 mA to 1000 mA on request.
