System Operations
• A solid-state charger transforms the incoming utility voltage
into a regulated DC supply voltage to charge the batteries.
• A maintenance-free battery is provided on standard models
to maintain power to the inverter. The batteries are fitted with
a suitably rated DC switch and fuse to provide overload and
short-circuit protection and also allow isolation from the system
for maintenance purposes.
• A high-frequency, pulse width modulated inverter transforms
the battery energy into low-distortion, no break, sine wave AC
voltage to supply the emergency load.
• 90% boost tap for line regulation protects against brownouts
and conserves batteries for emergencies.
