Affordable LED Independent Emergency Devices for Commercial Projects
The EMAI EK05 emergency driver delivers true constant power output (2W/3W/4W/5W options) to maintain consistent lighting levels during emergencies when it matters most. With a wide 20–300VDC output range, it automatically adjusts to match diverse LED loads, making it ideal for retrofitting or new builds across Europe. Certified to ENEC, CE, CB, UKCA, and C-tick, it complies with EN 60598-2-22 and other regional standards. Built-in monthly and annual self-diagnostic tests ensure continuous readiness, while lithium technology enables a compact footprint. In case of fault (e.g., over-discharge), charging halts automatically; once resolved, AC reactivates seamlessly. Designed for dry indoor use only. Backed by a 3-year warranty.
Top Features and Benefits:

Application Scenario
Commercial Buildings: Provides essential lighting in offices, retail spaces, and other commercial settings to ensure safety and operational continuity during power failures.
Product Advantages
1. ENEC Certified for Trusted Access Across Europe
The EMAI EK05 emergency LED driver is ENEC certified-a rigorous, third-party European safety mark far more trusted than basic CE. Recognized in over 20 EU countries, ENEC certification accelerates approval in demanding markets like Germany, France, and the Nordics. Combined with CB, CE, UKCA, and C-tick, the EK05 offers seamless compliance across Europe, the UK, Australia, and beyond-making it a truly global-ready solution for emergency lighting.
2.Safety-First Energy Storage
Engineered for reliability, this LiFePO₄ emergency power battery integrates an NTC temperature sensor to monitor real-time thermal conditions within its safe operating range of 0–60 °C. Unlike conventional lithium-ion chemistries, LiFePO₄ offers exceptional thermal and chemical stability, drastically reducing risks of fire or explosion. Its compliance with Regulation (EU) 2023/1542-verified under reference 2IFpR19/66-ensures adherence to stringent EU safety, sustainability, and labeling standards. Ideal for critical backup systems where safety and regulatory trust are non-negotiable.
Battery Parameters
Different battery capacities correspond to different emergency power outputs and emergency durations.
A larger battery capacity enables higher emergency power and longer emergency operating time, which can be flexibly configured according to project requirements.

Emergency Function
This is a maintenance-type emergency device. When the main power is connected, the green charging indicator light should illuminate, indicating that the battery has been correctly activated. The light will remain on. When the power is interrupted, the device will enter emergency mode and the indicator light will also illuminate. Testing and inspection must comply with local operating regulations.
Self-check function:
1. Green LED status light on: Normal charging mode, 200 - 240 volt power connected.
2. Monthly test, test duration 15 seconds.
3. 6-month test, test duration 3 hours.
4. Self-check tests are subject to EN62034 regulations.
LED indicator functions:
Off: Normal state, waiting for the next test.
Slow flash 1: 2 seconds on/2 seconds off: Self-check test in progress.
Slow flash 2: 4 seconds on/1 second off: Most recent self-check test completed and passed (stops after 5 days).
Fast flash: 0.5 seconds on/0.5 seconds off: Fault, replace battery or retest the device.
