LED Driver Module 250W
The LED Driver Module 250W is a high-capacity constant current/constant voltage power supply unit designed to efficiently drive high-power LED arrays and lighting systems with precision control and thermal management. Professional lighting designers, electrical contractors, and industrial automation engineers rely on this module to power demanding LED installations ranging from architectural lighting to industrial machine vision systems. This driver solves critical challenges in LED power delivery by providing stable output current regulation, preventing LED degradation, and enabling safe operation of expensive LED arrays in demanding environmental conditions.
Product Overview
The LED Driver Module 250W operates on the principle of switch-mode power conversion, utilizing advanced PWM (Pulse Width Modulation) technology to maintain constant current output regardless of input voltage fluctuations or LED load variations. The module features a wide input voltage range typically between 85-264V AC, allowing seamless operation across different power supply standards in India and internationally. Its isolated design provides galvanic isolation between input and output circuits, protecting sensitive LED systems from ground loops and voltage spikes that commonly occur in industrial environments. The compact form factor integrates multiple protection mechanisms including over-current shutdown, thermal cutoff, and short-circuit protection to ensure longevity of connected LED arrays.
What distinguishes this 250W driver is its exceptional efficiency rating above 90%, which translates to minimal heat generation and reduced operational costs over extended deployment periods. The module employs active power factor correction (PFC) to minimize harmonic distortion and comply with international power quality standards, making it ideal for both commercial and industrial applications. Its dimmable capability through 0-10V analog control or PWM signals enables dynamic brightness adjustment without affecting color temperature stability, critical for applications requiring precise lighting control. The robust aluminum heatsink design with thermal management ensures reliable operation even in high-ambient temperature environments up to 50 degrees Celsius.

How to Use
Installation of the LED Driver Module 250W requires careful attention to electrical safety and proper configuration. Begin by verifying that your AC input voltage matches the driver's 85-264V specification using a multimeter. Mount the driver on a DIN rail within an appropriate electrical enclosure, ensuring the aluminum heatsink has minimum 50mm clearance for natural convection cooling. Connect the AC input terminals to your facility's power supply through a 20A circuit breaker or fused disconnect switch for safety compliance. Configure the output voltage selector to match your LED array specifications, typically 24V for most commercial LED strings and 48V for longer runs with multiple series-connected LED modules.
Connect the LED load to the positive and negative output terminals, ensuring polarity is correct as reverse connection may damage the driver. For dimming applications, connect the 0-10V control signal to the designated dimming input terminals, or if using PWM control, ensure the PWM frequency is between 1-10kHz for optimal performance. After initial setup, apply AC power and verify output voltage using a DC voltmeter before connecting expensive LED arrays. Monitor the driver's operation for the first 30 minutes to ensure proper thermal behavior, with the heatsink remaining warm but not hot to touch. For installations requiring redundancy or load sharing, multiple 250W drivers can be paralleled by connecting outputs together with appropriate current-limiting diodes to prevent backfeed between units.
Frequently Asked Questions
What is the difference between constant current and constant voltage operation in this LED driver?
This 250W module operates primarily in constant current mode, which is essential for LED arrays where maintaining precise current ensures uniform brightness and prevents premature LED degradation. In constant current mode, the driver automatically adjusts output voltage to maintain the set current level regardless of LED load variations. Constant voltage mode is used for non-critical applications like simple LED strips where voltage stability matters more than current precision. This driver's dual-mode capability allows you to select the appropriate operating mode based on your specific LED array requirements, with constant current being the preferred choice for professional installations.
Can this 250W driver handle input voltage fluctuations common in Indian power grids?
Yes, the wide input voltage range of 85-264V AC makes this driver exceptionally suitable for Indian power conditions where voltage fluctuations between 180V and 250V are common. The driver's internal voltage regulation circuitry maintains stable output current even when input voltage varies significantly, protecting your LED arrays from the voltage instability that causes flickering and premature failure. Additionally, the integrated input surge protection handles voltage spikes that frequently occur during monsoon seasons or in areas with aging electrical infrastructure. For installations in extremely unstable power environments, we recommend adding an external voltage stabilizer for additional protection.
How do I calculate if the 250W driver is sufficient for my LED array?
To determine if a 250W driver suits your needs, multiply the LED forward voltage by the desired current: Power = Voltage × Current. For example, if you have LED strings requiring 48V at 5A, you need 240W, making the 250W driver suitable with 10W headroom for safety. Always select a driver with at least 20% power headroom above your calculated requirement to ensure thermal stability and extend driver lifespan. If your calculation exceeds 250W, you can either use multiple drivers in parallel or select a higher-capacity driver. Our technical team can help you perform these calculations for complex multi-string LED configurations.
What does the 0-10V dimming input do and how do I connect it?
The 0-10V dimming input allows you to control LED brightness smoothly from 0% to 100% by applying a variable DC voltage between 0V and 10V to the designated dimming terminals. A 0V input produces minimum brightness output, while 10V produces full brightness. This feature enables integration with building automation systems, daylight sensors, or manual dimming controls for energy management. To connect, use a shielded twisted pair cable from your control device to the dimming terminals, keeping the cable separate from AC power lines to avoid interference. The dimming response is linear, meaning 5V input produces approximately 50% brightness, making it predictable for automation programming.
Is this driver suitable for outdoor installations and what precautions are needed?
While the driver itself can operate in outdoor environments with temperatures between -20 to +50 degrees Celsius, it must be housed in a weatherproof enclosure to protect against moisture, dust, and UV exposure. The aluminum heatsink can oxidize in corrosive coastal environments, so consider applying protective coating or using stainless steel mounting brackets. Ensure the enclosure has ventilation holes or fans to maintain proper cooling, as the heatsink relies on airflow for thermal management. Use outdoor-rated connectors and cable glands rated for IP67 or higher to prevent water ingress. For installations near salt water or in highly corrosive environments, we recommend consulting our technical team for specific protection recommendations.
