The OTM-TD203500-740-38 is a constant current LED driver designed to power LED lighting fixtures. The model is equipped with a Triac dimming feature, allowing users to adjust the brightness of their lights. The driver has an input voltage range of 90-130V AC, an input current of 0.9A, and an input frequency of 50-60Hz.

The power factor of the driver is greater than 0.95, indicating that it is highly efficient in converting AC power to DC power. The efficiency of the driver is also greater than 85%, which helps to reduce energy consumption and operating costs.

The driver's output is a regulated current of 740mA, with an output power of 38W. The output voltage ranges from 42-54V DC, making it compatible with a wide range of LED lighting fixtures.

The driver is designed to operate in ambient temperatures up to 40°C, with a case temperature limit of 90°C. It has an IP20 rating, making it suitable for use in dry and damp locations.

The driver's dimensions are 139.63mm x 47.25mm x 28.86mm (5.5in x 1.86in x 1.13in), and it has Class 2 certification, indicating that it meets safety standards for low voltage applications.
Note: Never use constant voltage driver instead of constant current driver, even if Voltage and mA are equal.
