Emergency power

This Model allows power to be released in the case of a power cut in a stationary system. Switching to emergency mode is rare (the batteries are hardly used).

Types of automatic transfer to emergency power

  • Transfer switch: at power loss, a relay switches automatically to the emergency power supply. There is a transfer time (a few milliseconds) linked to the electronics.
  • On Line: Power consumed is supplied by an emergency system, itself driven by the mains grid. There is no micro power cut, since the electronics are solicited permanently.


The principal functioning of an "Emergency power system"

2 sockets are available to supply power to your equipment:
- 1 socket not on emergency power, directly linked to the mains, or not, at the entry of the energy system .
- 1 socket linked to emergency power, which withholds a provisionary source of power in case of mains power loss, voluntary or not. This outlet is supplied when connected to the mains and remains supplied with energy if the mains grid is cut.

In the event of mains power failure, the autonomy of the emergency power will depend on the amount of energy consumed by the equipment plugged in.


Solutions issued from this Model

  • Self-contained power pack for the tagging of cranes. To find out more.
  • Lighting of tunnels undergoing works, via two ramps wired in parallel: usually all the lights are lit up (maximum light); in the event of a power cut, the ramp connected to the mains turns off (anomaly detected) but the other ramp connected to the emergency power remains lit up (evacuation of personnel without panic).To find out more.
  • Independent emergency power supplies, for the deployment or the taking down of wind turbines in a temporarily non powered zone (e.g. during a tornado or heavy storm).
