EPS Emergency Power Supply EPS

Ultra-fast Automatic Switching, Meet Strict Fire Acceptance Standards

When commercial power cuts off, the unit switches to battery output within 0.2s without blackout gap, eliminating evacuation lighting interruption risks. Standard emergency backup time reaches 90 minutes, and we can customize 120/180-minute long-duration models for large public buildings, fully satisfying national and international fire inspection requirements.

Intelligent LCD Real-time Monitoring & Full Fault Self-alarm System

Built-in high-definition LCD screen to real-time display input voltage, battery residual capacity, load current and equipment operation status. It automatically detects battery aging, circuit short-circuit, overload and charging faults, triggering sound-light alarm and storing fault codes for quick troubleshooting, greatly reducing daily inspection workload.

Safe Lead-acid Battery Pack with Multi-layer Safety Protection

Adopts maintenance-free valve-regulated lead-acid batteries with independent separated battery compartment. Integrated multi-protection circuit prevents battery overcharging, over-discharging, overheating and short-circuit risks. The battery compartment is equipped with heat dissipation holes to avoid heat accumulation, with 6-year standard service life for battery cells.

Multi-power Customization, Dual Installation Structure Design

We provide power capacity ranging from 0.5kW to 30kW, classified into lighting-type EPS for emergency lamps and power-type EPS for fire pumps & fans. The cabinet adopts thickened cold-rolled steel plate anti-rust spraying, supporting wall-mounted small cabinet and floor-standing large cabinet to match electrical shaft and equipment room layout.

Fire Linkage Signal Interface, Compatible With All Fire Alarm Hosts

Reserves standard passive fire linkage signal terminals, which can be seamlessly connected to building fire alarm control panels. It can automatically adjust output power and emergency operation mode according to fire alarm signals, realizing partitioned evacuation power supply control for multi-area complex buildings.

◉ High-rise Commercial & Residential Buildings: Lighting-type EPS matches emergency exit lights and corridor evacuation lamps, automatically activating all emergency lighting after power failure to guide crowd evacuation during fire accidents.

◉ Hospitals, Malls & Subway Stations: Large-capacity floor-standing EPS serves dense public venues, long emergency duration ensures continuous evacuation lighting for large enclosed spaces with massive people flow.

◉ Underground Garages & Tunnel Projects: Compact wall-mounted EPS installed in electrical shafts, adapting to damp underground environment, stable power supply for underground smoke exhaust fans and emergency lighting.

◉ Factory Workshops & Industrial Parks: Power-type high-power EPS supports fire pumps, smoke exhaust fans and fire rolling shutters, providing stable backup power for fire fighting equipment in industrial production areas.

◉ Schools, Hotels & Office Buildings: Medium-power EPS centralized power supply for whole-building fire emergency system, compatible with mainstream fire alarm systems to realize automatic fire linkage control.

Check mains input circuit breaker and battery wiring tightness before power-on. Operate LCD panel to test emergency switching and fault self-check function. Cut off main power to simulate power failure and verify stable emergency output. Download full English operation PDF for fire linkage wiring and parameter setting steps.

Q: What is the difference between lighting-type EPS and power-type EPS?

A: Lighting-type EPS is low-power specially for emergency evacuation lamps, with small cabinet size and wall-mounted design. Power-type EPS is high-power to drive heavy loads like fire pumps and exhaust fans, adopting floor-standing large cabinet structure with strong instantaneous load capacity.

Q: Can this EPS be connected to the building fire alarm control host?

A: Yes. It reserves standard passive linkage signal interface. Once the fire host sends alarm signal, EPS will instantly switch all output to emergency power mode without extra wiring transformation.

Q: How long can the built-in lead-acid battery work normally?

A: The standard service life of our maintenance-free lead-acid batteries is 6 years under regular charging and maintenance. We can also customize lithium iron phosphate battery models with 10-year service life for long-term unattended equipment rooms.

Q: Is the EPS cabinet suitable for damp underground parking lots?

A: Yes. IP30 sealed cabinet with built-in heat dissipation vents. We can add optional dehumidification fans to prevent moisture condensation, avoiding circuit short-circuit caused by underground high humidity environment.

Q: Can I customize longer emergency backup time for special projects?

A: Absolutely. Standard emergency duration is 90 minutes to meet fire acceptance criteria. For hospitals, large shopping malls and tunnel projects, we can expand battery capacity to realize 120 or 180 minutes continuous emergency power supply.
