LED Driver 24V 100W 4.2A For LED Spot and Strip


TILLUME transformer integrates a switching mode power factor correction (TM PFC) controller and a quasi- resonant controller (QR) controller. PFC controllers provide a cost-effective solution for optimizing power factor.  QR controllers have higher efficiency and lower electromagnetic interference compared to traditional PWM systems,.

TIECO transformer provides advanced integration and high performance than conventional  PFC/PWM system. The built-in TM PFC controller optimizes power conversion efficiency by reduced system costs. The intelligent PFC switch on and off, zero current detection, and frequency limiting mechanisms can achieve better efficiency under any load condition.

TIECO LED driver has many built-in green features to optimize power conversion efficiency. 

This LED transformer also integrates multiple protection functions, such as X-CAP discharge, break protection, unde voltage lockout, PFC and QR level cycle by cycle current limiting (OCP), PFC and Q R level output over voltage protection (OVP), PFC and Q R level open loop protection (OLP). Therefore, it can protect the system from damage caused by occasional failures.

1. AII parameters NOT speciaIIy mentioned are measured at 230VAC input, rated current and 25C of ambient temperature.
2. RippIe & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf paraIIeI capacitor.
3. ToIerance : incIudes set up toIerance, Iine reguIation and Ioad reguIation.
4. De-rating may be needed under Iow input voItages. 
5. Length of set up time is measured at first coId start. Turning ON/OFF the driver may Iead to increase of the set up time.
6. The driver is considered as a component that wiII be operated in combination with finaI equipment. Since EMC performance wiII be affected by the compIete instaIIation, the finaI equipment manufacturers must re-quaIify EMC Directive on the compIete instaIIation again.
