■ Description
GSC18B series is a 18W external desktop LED power supply with PFC function. The design of this product is
based on the “ plug and play ” concept for adaptors. The AC input side exploits the 2-Pin (Class Ⅱ, no FG)
international standard inlet IEC320-C8, and the output side is equipped with the highly accepted DC
connector (2.1x5.5x11mm) in the market. This product accepts 90~277VAC input and offers various
constant current output models with 350mA/500mA/700mA/1050mA/1400mA. The design complies with
the lighting requirements of EMI EN55015 and the harmonic current demand per EN61000-3-2 Class C.
In addition, the no load power consumption is less than 0.15W, and the setup time is less than 500ms,
making GSC18B conform to the ErP regulation required by European Union for lighting systems as well.

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Please see "AC input voltage drop vs. output current characteristics" table.
4. Constant current operation region is within 50% ~100% rated output voltage. This is the suitable operation region for LED related applications, but please
reconfirm special electrical requirements for some specific system design.
5. Direct connecting to LEDs is suggested, but is not suitable for using additional drivers.
