Benefits of a DC Output Emergency Driver
The primary benefit of a DC output emergency driver is its straightforward reliability. By bypassing the fixture's standard driver—a common point of failure—it creates a completely independent backup system. This design is often more energy-efficient, as it avoids the power loss that can occur when converting battery DC power to AC and back again. The result is a dependable and efficient emergency lighting solution that ensures your LEDs will turn on when they are needed most.
Matching the Voltage of Your DC Emergency Driver
A critical specification for any DC output emergency driver is its output voltage range. For the driver to function correctly, the forward voltage (Vf) of your fixture's LED module must fall within this range. For example, if your LED module requires 36V, you must select a driver with a range that includes 36V, such as one rated for 20-50VDC.
Most drivers in this category are designed to be NEC Class 2 compliant, a safety standard that limits power sources to be safe from fire and shock hazards. For this reason, the vast majority of these DC output drivers have a maximum output voltage of 60V DC and a power limit of 100W. This Class 2 rating often simplifies installation requirements, making these drivers a safe and convenient choice.
Ideal Applications for DC Emergency Drivers
DC output emergency LED drivers are a versatile solution, but they are particularly well-suited for luminaires where the LED array is easily accessible. Common applications include:
- LED Troffers and Panels: Widely used in offices and schools, these fixtures have ample space for an internal emergency driver.
- Downlights: A compact DC driver can provide emergency lighting in hallways, lobbies, and retail spaces.
- Strip and Cove Lighting: Ensures that architectural and accent lighting can double as a safe path of egress.
Installation Options for DC Emergency Drivers
DC output emergency drivers come with different wiring configurations to suit various installation needs. Choosing the right one can simplify your project and ensure a secure, code-compliant connection.
- Flying Leads (Wire Leads): This is the most common option, featuring flexible, pre-stripped wires extending directly from the driver's housing. These leads offer versatility and are designed to be easily connected with wire nuts inside a fixture's wiring compartment or a separate junction box.
- Flexible Conduit: For applications where the driver is mounted externally, many models come with a length of pre-attached flexible metal conduit. The wires are already run through this conduit, providing protection and making it easier to complete a clean, professional installation.
- Terminal Block: Some drivers feature a terminal block with screw-down connections, typically housed within an integrated junction box. This allows an installer to land the building and fixture wires directly onto the driver for a very secure and robust connection.
