A constant-voltage power supply is designed to provide a stable output voltage regardless of changes in the load or input voltage. These power supplies will supply an output current up to their maximum rating based on the requirements of the products they are powering. A constant-voltage power supply is needed when an electronic or LED light requires a different voltage than what is supplied by the mains. These power supplies are most commonly used with LED strips.

A constant-current driver regulates and maintains a steady current within a specific voltage range. Since LEDs are current-driven devices, they require a specific operating current to operate properly. Some drivers can lower and adjust the output voltage if needed. Constant current drivers are most commonly needed when the existing driver has failed or if you are manufacturing a device and need to drive an LED array directly.

An emergency backup driver is designed to provide power to LED fixtures during a power outage. These drivers feature a battery backup that charges during normal operation and switches to battery power when the main power supply fails. This ensures that essential lighting remains operational in emergency situations. Emergency backup drivers are required in commercial applications where the building code requires emergency egress lighting.

To ensure your lighting system can have full dimming capabilities, choose an LED driver that is compatible with the dimming type of your light and any existing switches. A dimmable LED driver allows for the adjustment of brightness to create different atmospheres and save money on energy costs. DiodeDrive carries power supplies that are compatible with the following dimming types: 0-10V, PWM, TRIAC, and Potentiometer dimming.

Choosing waterproof and weatherproof power supplies ensures that all parts of your lighting system remain protected against water intrusion. Waterproof drivers are suitable for wet locations and outdoor applications where you need to convert high-voltage AC power into low-voltage DC power.

There are various enclosure options available for LED drivers. Enclosed drivers with a built-in junction box provide a clean, professional-looking way to store your power supplies while ensuring that no wires are touched.

DiodeDrive’s high-performance LED drivers are available in a wide range of input voltage options, including up to 347 VAC. This makes our power supplies suitable for various high-power commercial applications.

If you notice that your LED lights are flickering, dimming unexpectedly, or not lighting up at all, it may be time to replace the LED driver, especially if the driver has a shorter lifespan compared to the LED chips themselves. When choosing an LED driver, consider the following specifications:

• Output Voltage: Ensure the driver's output voltage matches the requirements of your LED fixtures. The most common output voltages for strip lights and light bars are 12V DC or 24V DC, whereas the output voltage for troffers and fluorescent tube replacements can range higher.
• Output Power: The driver's wattage should be suitable for the total power consumption of your LEDs or electronic devices.
• Input Voltage: Verify that the driver is rated for the input voltage of the main power line. The most common input voltages are 120 VAC and 240 VAC, but DiodeDrive carries LED drivers with an input voltage ranging up to 347 VAC as well.
• Output Rated Current: Constant current drivers should supply the appropriate maximum current for your LEDs to prevent overdriving.
