LED Power Supply Efficiency Showcase
How TMT LED power supplies achieve 88-93% efficiency through Active Power Factor Correction, IP67 waterproof protection, and multi-circuit Class 2 architecture.
Key Efficiency Stats
88-93% Efficiency
TMT power supplies convert 88-93% of input power to usable DC output. Active PFC models achieve the higher end of this range.
Active Power Factor Correction
Active PFC corrects the phase relationship between voltage and current, reducing harmonic distortion and improving power quality on the electrical system.
IP67 Waterproof
IP67 rating means the supply is protected against dust ingress and temporary immersion in water. Suitable for dry, damp, and wet locations per UL8750.

Frequently Asked Questions
What is Active Power Factor Correction?
Active PFC is a circuit that corrects the phase relationship between voltage and current in the power supply. This reduces harmonic distortion, improves efficiency, and meets international energy standards. TMT PFC models achieve 88-93% efficiency.
Why does IP67 matter for sign lighting?
IP67 means the supply is dust-tight and can withstand temporary water immersion. For sign lighting, this means the supply can be installed in wet locations such as outdoor signs, car wash facilities, and other exposed environments.
What does the 305V input ceiling mean?
TMT power supplies accept input voltages from 100V to 305V AC. This wide input range supports commercial electrical environments worldwide without requiring separate models for different voltage standards.
What protections are built into TMT power supplies?
All TMT power supplies include over-current protection (OCP), over-voltage protection (OVP), short-circuit protection (SCP), and over-temperature protection (OTP). These protect both the supply and the connected LED modules.
