EPS Emergency Power Supply — Fire Emergency Inverter Systems
EPS (Emergency Power Supply) systems provide automatic AC backup power for fire protection and emergency loads during a mains failure, using inverter technology with a battery bank and automatic transfer. Available in lighting-type (for emergency lighting and evacuation signs) and power-type (for fire pumps, smoke exhaust fans, and elevators) configurations from 1 to 500 kW, single-phase 220V and three-phase 380V output.

- Frequently Asked Questions
What is the difference between EPS and UPS?
An EPS supplies fire protection and emergency loads only during an outage and may start in standby (off-line) mode, while a UPS continuously conditions power for sensitive electronic loads with zero transfer time. EPS is normally sized for 90-minute fire duty and motor loads.
What loads can an EPS drive?
Lighting-type EPS drives emergency lighting; power-type EPS drives inductive loads such as fire pumps, smoke fans and elevators, sized for motor starting current.
How long must an EPS run on battery?
Fire codes commonly require at least 90 minutes of battery autonomy for emergency lighting and fire equipment.
