Soft Start: This is a limiter that can be either added into the power cart during manufacturing or at a later date. It limits the output current of the unit and will allow the voltage to automatically decrease as more current is drawn from the unit. Its purpose is to soften the inrush of current when the starter of a turbine engine is first engaged to protect the starter from being over torqued and the solenoid contacts from arcing. Starting current will be limited to approximately 1000 amps when using the soft start. On inrush, the soft start drops the voltage as needed to limit the current to around 1000 amps in order to stay connected. As the engine spools up, the voltage will return to 28 volts. On some aircraft, the battery must be turned on in order to be able to inject external power into the start system. In this type of arrangement the aircraft batteries and power cart are in parallel. On a start, the engine draws power from both the batteries and the power cart. If the soft start is switched on the batteries will furnish about 80% of the power and the power cart about 20%. With the soft start switched in normal position, or out of the circuit, the reverse is true, 80% will come from the power cart and 20% from the aircraft batteries as it should. On aircraft where the start can be supplied from external, the power cart will supply 100% of the power.
115 VAC Outlet Step Down Transformer: Units operating above 240 VAC require a step-down transformer for the 115V outlet to be operational.
Service Outlet Transformer – on 440 or 460: When the power cart is used on 440 or 460 volts AC lines, the service outlet transformer will reduce the line voltage to 115 volts and provide up to 5 amps for service equipment and drop lights.
14/28V Output Retro-Fit: This converts existing power cart to 14 or 28 volts output. (600 amp peak output on 14 volt range, limited to units operating from 208 to 240 volt input)
