EL300 models are designed to provide three phase input and output as required by the latest European EN 50171 specification for Emergency Lighting. The significant advantage of using PowerPro EL Static Inverters for Emergency Lighting is the ability to supply tightly regulated and controlled sinewave power to a wide range of normal functional or decorative mains luminaires as emergency fittings.

EL300 models have three phase rectifiers with "Soft Start" control incorporating thyristor-controlled bridge circuitry to limit inrush current and prevent overloading marginally rated mains supplies. These models provide an excellent solution for higher power, three phase loads and can also reduce the need for extensive re-cabling during installation.

All PowerPro EL Static Inverters are simple and easy to install with input and output terminals conveniently positioned with front access, ensuring ease of positioning and trouble-free installation and maintenance. Low MTBF (mean time between failure) and low MTTR (mean time to repair) are both fundamental to the PowerPro EL design.
