Output impedance shall be 3.0 to 5.0 percent,The card shall be manufactured such that it will maintain electrical properties, even under severe overload, under/over voltage and under/over frequency conditions. Input correction range shall be -30% to +20% of nominal input voltage. The system design shall be capable of operating at an input frequency range of -15% to +10% of nominal, without clearing protective devices or causing component failure within the Microprocessor Card. Upon turn on or restart, the output of the Microprocessor Card shall not exceed the specified output regulation limits. if the input voltage or frequency exceeds programmable minimum or maximum set points for a programmable time period (factory set for 10 seconds), the Microprocessor Card shall electronically shut off. When electrical parameters are back within acceptable limits for a programmable time period (factory set for 60 seconds), the Microprocessor Card shall automatically restart to provide conditioned power to the load. If the input parameters are within acceptable limits, but the output voltage is outside of acceptable programmed limits, the Microprocessor Card shall electronically shut off and require a manual restart. The Microprocessor Card shall be capable of operating at 100% rated load capacity continuously, 200% rated load for 10 seconds, 500% rated load for 1 second and 1000% rated load for 1 cycle.
