The EPS system researched and manufactured by SIGA company is
mainly made of rectifiers, static switch modules, manual bypass
switching, control cells, retransformation equipment, machine
framing, storage battery' s. Retransformation equipment is core.
The action of the rectifier is to change AC into DC to provide
charging for storage batteries and supplying electricity to
retransformation modules. The retransformation equipment change DC
into AC to supply electric power load equipment that is stable and
constant. Static switching can be set up to mothball or use online
working modes an adjust the output of retransformation equipment
and municipal electricity at the same time to ensure the load is
smoothly changed between them. Manual bypassing can swich can
change the load into municipal electricity and isolate with system.
In this way it isn' t possible to block the normal work of load
equipment when maintaining the system.There is a monitor of the
whole system which can give an alarm, at the same time, it is
possible to connect the serial mouth with a computer or Modem to
provide long-range monitoring of an electrical supply system.
