China EPS Fire Emergency Power Supply – Reliable Suppliers & Factory for Fire Protection Solutions

💡

Primarily used to provide centralized power supply for emergency lighting fixtures during building fires or emergencies.

⚡

Capable of supporting both emergency lighting and mixed loads such as fire pumps and fire elevators.

🔄

Specifically designed for power loads like electric motors, providing a variable-frequency three-phase emergency power system that supports soft motor starts to reduce startup impact.

Incorporates redundant design with forced start, overload operation, and segmented battery management to ensure continuous power supply during emergencies.

Switching time between utility power and emergency power typically under 5 seconds (millisecond-level for select models), meeting fire protection systems’ demand for instantaneous power supply.

Equipped with smart monitoring and alarm functions to track real-time power status and battery health, facilitating timely maintenance and management.

Capable of handling capacitive, inductive, and mixed loads with robust overload capacity and surge resistance, suitable for diverse complex environments.

Provides power support for emergency lighting, fire pumps, fire elevators, fire alarm systems, and other fire protection equipment.

Ensures emergency power supply for critical areas like operating rooms and intensive care units, maintaining uninterrupted medical operations.

Provides backup power for road lighting, tunnel illumination, electrical facilities, industrial plants, and mining operations.

Delivers standby power to high-demand equipment in chemical, metallurgical, and electronics industries, preventing production halts and equipment damage during outages.

Q What are the main types of EPS fire emergency power supplies?

EPS fire emergency power supplies are available in three main types: Emergency Lighting Type (for centralized emergency lighting), Hybrid Type (supporting both lighting and mixed loads such as fire pumps and elevators), and Power Inverter Type (designed for motor-driven equipment with soft-start capability).

Q How fast is the switchover from mains power to emergency power?

The standard conversion time is less than 0.5 seconds. Certain high-performance models offer millisecond-level switching, ensuring fire protection systems receive instantaneous and uninterrupted power during an outage.

Q What type of battery does the EPS system use, and how long can it last?

The system uses LiFePO4 (Lithium Iron Phosphate) batteries operating at 153–614VDC. Both standby time and charging time can be configured between 1 and 24 hours based on specific design requirements.

Q What protection and alert functions are built into the EPS system?

The system includes overload protection during emergency state, output open-circuit and short-circuit protection, and battery under-voltage protection. Alerts are triggered for conditions such as battery under-voltage, battery connection failure, charger malfunction, sustained overload, and inverter failure.

Q In which industries and environments can EPS fire emergency power supplies be used?

EPS systems are suitable for a wide range of applications including building fire protection, hospitals and medical facilities, public infrastructure (roads, tunnels, mines), and industrial sectors such as chemical, metallurgical, and electronics manufacturing. They operate in temperatures from -20°C to 55°C and at altitudes up to 2000m.

Q What is the rated capacity range and output quality of the EPS system?

The EPS system supports rated capacities from 16kWh to 800kWh. Emergency output delivers a pure sine wave at 380V ± 3%, with a Total Harmonic Distortion (THD) of less than 5% under linear load and an inverter efficiency exceeding 92%, ensuring stable and clean power for sensitive equipment.
