What this unit does

The LED-EMB-8W-LV-INT provides automatic emergency power to LED luminaires on AC power loss, switching to its internal battery to deliver up to 8W of DC output for emergency illumination, and returns to charging mode when AC power is restored.

• Automatic transfer to emergency mode when AC power is interrupted
• Illuminated test switch and indicator for function verification

Input and output electrical requirements

This unit requires an unswitched AC supply on the same branch circuit as the luminaire. It charges from 100–277VAC and supplies low‑voltage DC to the luminaire/LED driver during emergency operation per the manufacturer‑specified output range.

• AC input: 100–277VAC, 50/60Hz
• AC input current: 250mA max; AC input power: 7.0W max
• Output: 8W emergency output; output current/voltage range: 160–3200mA, 25–48V DC (manufacturer data)
• During normal AC operation, follow manufacturer guidance that the connected LED driver output current should not exceed 2A

Installation and mounting notes

Intended for use installed inside grounded, UL‑listed luminaires. Installation requires familiarity with luminaire electrical systems; a qualified electrician should perform installation and follow the manufacturer’s wiring and safety instructions.

• Do not mate the battery connector until installation is complete and AC power is present, per manufacturer instructions
• Unit must be enclosed within the luminaire and bonded to the luminaire grounding
• Do not use outdoors; use only with luminaires rated by their manufacturer for internal mounting of battery packs
• Follow local electrical codes and the manufacturer's wiring diagram

Battery, runtime and limits

The unit uses an internal 7.4V Li‑ion battery (2500mAh) with built‑in protections. Manufacturer specifies a 1.5 hour emergency runtime and a battery life of approximately 500 standard charge/discharge cycles.

• Emergency runtime: 1.5 hours
• Battery: Li‑ion 7.4V / 2500mAh with over‑charge, over‑discharge and short‑circuit protection
• Battery charging current: 250mA max; typical charging time: 24 hours
• Operating ambient for battery: 0°C to +50°C (32°F to 122°F)

Dimensions and packaging

Confirm internal luminaire space before ordering. The case is compact and designed to be mounted inside fixtures that provide internal housing space.

• Case dimensions: 7.4" x 1.5" x 0.95" (188mm x 38mm x 24mm)
• Battery pack is secured by screw; indicator lamp attached per manufacturer (3M tape noted)
• Box quantity: 4
• UPC: 819715023866

Before You Order

Confirm the target luminaire has internal space to enclose the battery pack and an unswitched 100–277VAC branch circuit on the same circuit as the luminaire.

• Verify the luminaire is UL‑listed and suitable for internal mounting of a battery backup.
• If unsure about electrical compatibility or installation, consult a qualified electrician.
