The OTTIMA OTM-TD9 Constant Current LED Driver is an electronic device that supplies a regulated constant current to LED lights. The model number of this driver is OTM-TD9. It has an input voltage range of 90-130V AC with an input current of 0.1A and a frequency range of 48-62Hz. It has a high power factor (PF) of greater than 0.95, which means it is highly efficient in converting the input power to output power. The efficiency of this LED driver is greater than 85%.

The output regulated current of this LED driver is 190mA, and its maximum output power is 9W. The maximum voltage range of the output is 24-48V DC. It is dimmable with Triac Dimming, which allows for control of the brightness of the LED lights. The LED driver has an ambient temperature (Ta) of 40°C and a case temperature (Tc) of 90°C.

The LED driver is rated IP20, which means it is suitable for indoor use only. It has a compact size, with dimensions of 94 x 36 x 18.5 mm (3.7 x 1.42 x 0.72 in). The LED driver is certified as Class II, which means it has double insulation and does not require a grounding wire. Overall, this LED driver is a reliable and efficient solution for powering LED lights in indoor settings.
Note: Never use constant voltage driver instead of constant current driver, even if Voltage and mA are equal.
