LUMITRONIX micro constant current source

Constant current source 1, 20 or 50mA for easy operation of small current LEDs.

Constant current sources are particularly well suited to start up one or more LEDs safely and professionally. Especially when the input voltage is not constant (car sector or alternating current), constant current sources offer a convenient way to connect LEDs directly to this current source without great effort.

Technical specifications

• Minimum input voltage: 7VDC or 6VAC
• Maximum input voltage: 37VDC or 26VAC
• Power dissipation: max. 500mW at 20°C
• Output current: 1 mA, 20 mA, 50 mA (depending on the type selected)
• Output Current Tolerance: 2-5%
• Dimensions: 17.0x9.4x3.5mm
• Operating temperature: -20°C to 60°C

Security

• Thermal protection: If the constant current source gets too hot, it automatically reduces the current
• The input is protected against polarity reversal
• The output is voltage-proof and short-circuit proof

The following number of LEDs can be connected in series to the power source depending on the input voltage:

07V = 1 LED | 12V = 2 LEDs | 14V = 3 LEDs | 18V = 4 LEDs | 21V = 5 LEDs
25V = 6 LEDs | 28V = 7 LEDs | 32V = 8 LEDs | 35V = 9 LEDs
