The Static Frequency Converter 1BR3000B30A provides a high quality output of 115v 400hz 1 @ 3000VA from an input of 440v 50/60hz. The integral valve regulated lead acid battery supports the output for 30 minutes in the event of an input supply failure. The SFC also has a fabricated steel container that deck mounts with top steadies. A hinged cover that opens to the left at the front of the unit provides easy maintenance access. Furthermore, louvers provide fan assisted cooling during normal operation, while natural convection operates when the Anti Condensation Heaters are on.
Electrical connections to and from the SFC occur on the top mounted removable gland plate. The SFC also has a battery monitoring option that continuously monitors the state of the batteries. An alarm is raised if there is a battery imbalance (due to a short circuit cell) or if there is a hydrogen concentration of >1%.
The 115V 400hz output is high quality achieved with a crystal controlled inverter that has feedback loops. These feedback loops enable the control board to respond rapidly and smoothly to the demands of the output circuits. Closed loop operation also reduces line and load regulation of the SFC output. Finally, the built in battery charger can recharge a depleted battery to 80% charge in 8 hours.
