LED Drivers

LED drivers, also known as LED power supplies, are designed to provide the optimal current and voltage supply to LED light sources. LED drivers are available in a variety of designs including AC/DC converters, DC/DC converters, AC/DC power conversion modules, and cooling and mounting components. In addition, LED drivers can also provide protection against surge, voltage, and current overload.

The TRC-025S105PS LED Driver is one such driver that provides a reliable and cost-effective way to drive high currents to LED light sources. It offers a wide range of adjustable parameters, including input voltage range, output current range, dimming range, and thermal protection. Furthermore, the TRC-025S105PS has a very low standby current and a low voltage drop that ensures superior performance in applications where energy efficiency is important.

Application Fields and Working Principle

The range of application fields and applications of the TRC-025S105PS LED drivers are quite broad. It can be employed in a variety of lighting systems, including accent lighting and architectural lighting, landscape lighting, exit signs. The driver can also be used in LED strip lights, LED spotlights, and other general lighting applications. In addition, the TRC-025S105PS can also be used in applications such as automotive lighting and specialized solar LED lights.

The TRC-025S105 PS LED driver makes use of a wide-dimming range of 0.1V-48V. It has a maximum output current of 105A and output power of 250 watts. It has a wide input voltage range of 90-265VAC, wide ambient temperature range of -40 to +85℃, and excellent heat dissipation to ensure reliability and long life. This LED driver comes with an internal over voltage protection, short circuit protection, open circuit protection, and reverse polarity protection.

The main working principle of the TRC-025S105PS LED drive is pulse width modulation (PWM). This is where the input voltage is converted into a series of digital pulses in which the duration of each pulse is proportional to the input voltage. The output voltage is a function of the ratio of the "on" time versus the "off" time. This technique ensures high efficiency, stability, and good dimming control.

The TRC-025S105PS LED driver also includes protections to safeguard itself against overcurrent, overheat, and short circuit. Furthermore, an overvoltage protection is included to protect against accidental voltage spikes. The built-in thermal protection will also automatically limit output current under heavy loads which reduces the effects of thermal runaway.

The TRC-025S105PS LED driver boasts of excellent performance in terms of reliability, cost-effectiveness, and safety. It is suitable for a wide range of applications, including various lighting systems, automotive lighting, and specialized solar LED lights. It is compatible with various digital controllers and offers wide input voltage range, dimming range, and current protection.
