EPS Emergency Power Supply Overview
EPS (Emergency Power Supply) systems provide battery-backed AC power for emergency lighting, fire protection and critical loads during a mains failure. QDTB EPS systems are rated 50–300 kW with 90 or 120 minute backup, available in lighting-type, power-type and fire-linked configurations for buildings, hospitals and industrial facilities.
Available Series
Lighting Type Series
The lighting-type EPS (Emergency Power Supply) provides battery-backed AC power for emergency lighting and evacuation loads during a mains failure. Rated 50–300 kW with a backup duration of 90 or 120 minutes, it automatically transfers the emergency lighting circuit to the inverter within seconds of a power loss, ensuring exit and stairwell illumination for safe evacuation.
Power Type Series
The power-type EPS (Emergency Power Supply) provides battery-backed AC power for motor and critical process loads during a mains failure. Rated 50–300 kW with 90 or 120 minute backup, it delivers the high inrush capability needed for fire pumps, elevators and essential equipment, with robust overload performance and fast transfer to the inverter output.
Fire Linked Series
The fire-linked EPS (Emergency Power Supply) integrates with the building fire-alarm and fire-control system, receiving start and interlock signals from the fire protection panel. Rated 50–300 kW with 90 or 120 minute backup, it powers fire pumps, smoke-exhaust fans and emergency lighting with coordinated control, priority load shedding and status feedback to the fire alarm system.
