Line - interactive UPS is an electronic device that continues to supply electric power to the load for a certain periods of time during a loss of utility power. This unit under normal condition smoothes and to some degree regulates the input AC voltage by a filter and a tap-changing transformer. The bi-directional inverter/charger is always connected to the output of the UPS and uses a portion of AC power to keep the battery charged. When the input power fails, the transfer switch disconnects AC input and the battery/inverter provides output power. Its typical efficiency is 90-96%.
Line Burners are also utilized to heat tanks and solder baths that require a temperature range of approx. 210-260oC. Line burner assembly is provided for burning a mixture including at least a gaseous fuel and process air to produce a flame. The assembly includes a mixing region, which contains an air/fuel mixture. Gaseous fuel and process air are supplied to the mixing region. The application includes ovens and heating stationary objects.
