Emergency lighting can be supplied by a variety of sources, such as batteries or static inverters, which can run on a normal mains supply, providing enough power to run several electrical devices. The type of battery used in a static inverter system is important because of cost, expected life and safety elements.

Soft starter applications and user options
Article Abstract:
Soft starters offer many advantages over direct-on-line starting for induction motors. Soft starters allow a motor driving equipment to start or stop more slowly. This saves on starting currents, prevents damage to the goods being processed, and protects pipelines. Soft starters are installed between the mains contactor and a power lead linked to the motor.
