The dimming adjustment output of the GP-TH120N-24V LED driver ranges from 1% to 100%. Works with leading edge and trailing edge TRIAC dimmers. The typical power conversion efficiency is 84%. It supports an AC input voltage range from 205 to 256 VAC.

Wiring-DiagramThe fully isolated case design enables an operation temperature range of -20°C to 50°C, which means that the LED driver can be used in most environments. Additionally, with IP67 approval as well as four different protections: Over-Voltage Protection (OVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP) and Over-Temperature Protection (OTP), these drivers are highly secure.
