LED Driver and Emergency Control Unit

Introduction

This is a new generation of direct-drive emergency power supply designed specifically for LED lighting fixtures. Utilizing an isolated circuit topology and digital control technology, the unit integrates with a standard LED driver and an emergency battery to form a complete normal/emergency lighting system. The output of the standard LED driver connects to the light source via the emergency control unit; during normal operation, the LED light source is powered by the standard driver while the emergency control unit charges the battery. Upon a power failure, the emergency control unit automatically switches to emergency mode within 0.3 seconds, boosting the battery voltage to the level required to drive the LED light source. The product features an output interface for a status indicator light to display various operating states. It is suitable for a wide range of LED lighting fixtures requiring emergency functionality.

Product Features

This is a standalone emergency control unit specifically designed and developed by our company for LED lighting fixtures. With the continuous emergence of new materials, technologies, and manufacturing processes in recent years, a wide variety of LED drivers have been produced, marking a critical period of technological upgrading in the lighting industry. The 1106001 series emergency control unit utilizes a state-of-the-art isolated circuit topology, featuring comprehensive circuit design and digital control. Key characteristics include low noise, energy efficiency, environmental friendliness, high efficiency, input-output isolation, direct emergency driving of the light source, integration with the fixture housing, and rapid heat dissipation.

Product Performance

Open-Circuit Protection: If there is no load or an open circuit at the output, the unit immediately switches to a constant-voltage state to prevent damage caused by excessive output voltage; it automatically resumes constant-current operation once the open-circuit condition is resolved.
Short-Circuit Protection: In the event of an output short circuit (positive and negative terminals connecting), the unit automatically halts output to prevent permanent damage. Normal constant-current or constant-voltage operation resumes immediately after the short circuit is cleared.
Overload/Light-Load Protection: Designed for constant-current operation, the unit maintains a steady output current when the load is within the specified design range. If the load falls outside this range, the unit enters a protection mode: 1) If the output voltage is too low, the driver enters a cycle of frequent startup and shutdown, causing the LEDs to flicker; 2) If the output voltage is too high, the unit switches to constant-voltage protection mode, resulting in reduced LED brightness and an inability to reach the default current value.
Battery Overcharge Protection: The controller employs voltage-limited constant-current charging; when the voltage of an individual battery cell reaches 1.42V, the controller switches to trickle charging.
Battery Over-Discharge Protection: The controller automatically cuts off the output power when the voltage of an individual battery cell drops to a level within the 0.9V–1.1V range. Withstand Voltage: 1500V ±10% / 5mA / 1min / 50Hz between the main power input and the enclosure;
500V ±10% / 5mA / 1min / 50Hz between external live terminals and the enclosure.
Insulation Resistance: ≥50MΩ between the main power input and the enclosure;
≥20MΩ between external live terminals requiring insulation and the enclosure.
Indicator Light Function: External red LED (DC 1.9–2.2V); steady on during mains power operation; flashes evenly at 1Hz during emergency mode; flashes rapidly at 3Hz prior to the end of the emergency mode.

Precautions for Use and Installation Instructions

Precautions for Use:
1) The input voltage must be within the specified operating range of AC 100V–277V.
2) The product should be used within its rated ambient temperature range; ensure the power supply has adequate space and a suitable environment for heat dissipation.
Installation Instructions:
1) Connect the power supply to a mains power source equipped with a protective earth (ground) connection to ensure operator safety.
2) Wire the unit strictly according to the terminal locations indicated on the housing label. Ensure connections are secure and verify that input and output lines are not reversed, and that battery polarity is correct.
3) Connect the power supply only after confirming that the load specifications fully match the power supply system specifications.

Abnormalities and Troubleshooting

1) If the unit fails to light up or exhibits other issues after the initial electrical installation, disconnect the AC input and check for correct wiring, as well as for any poor contact at the output or AC input terminals.
2) If the LED lights up after installation but the output is abnormal, disconnect the AC input and check the DC output for overload or light-load conditions.
