The low dc voltage is converted into a pure sine wave using solid state power electronic devices, the frequency of the output voltage is crystal controlled for accuracy and stability. The dc input voltage is sampled in order to detect either a low or a high input and generates an alarm signal plus an output drive shutdown. Similarly the internal heat sink temperature is monitored and if a high temperature is detected an alarm signal plus an output drive shutdown occurs until the temperature has dropped to a safe level when the unit will automatically switch back on. The dc input current draw is measured in order to detect an overload, if an overload exists an alarm plus an output drive shutdown is generated. If during the slow start switch on an overload is generated the unit will continue to generate the alarm/shut down signal until the overload is reduced.
