2.5.7.2 Fault Clearing: Sub-cycle current of at least 300% but not more than 500% of normal full load current.

2.6 Battery DC ripple voltage.

a. During either cycle service or bulk phase of charging DC ripple voltage is maximum 2.0% RMS of the float voltage.

b. During float phase of charging DC ripple voltage is maximum 1.0% RMS of float voltage.

2.7 Low battery voltage protection: To prevent total discharge of the battery, the UPS shall automatically shut-down when the battery voltage reaches a preprogramed minimum voltage level. If the shut-down was caused by loss of AC input, then when power is restored normal system operation automatically resumes.

2.8 System Operation, Normal System Operation: The battery unit shall not be required to assume any portion of a critical load increase in normal operation. The UPS shall continue to function in the normal mode of operation with or without a DC source.

2.8.1 Normal Mode: During normal operation the UPS shall be used to provide precise regulated and transient free power to the electronic equipment load. The primary AC source shall be used to supply power to the rectifier charger. The rectifier charger shall provide regulated DC power to support the inverter and simultaneously maintain the battery in a fully charged condition. The inverter shall convert the DC power into regulated AC power for the load.

2.8.2 Emergency Mode: Upon failure of the primary AC power, input power for the inverter shall automatically be supplied from the battery. When normal power is restored, input power for the inverter and for recharging the battery shall automatically be supplied from the rectifier charger. If the input AC power does not return, the UPS shall automatically shut down in an orderly manner when the discharge limit of the battery is reached.

2.8.3 Bypass Mode: If the UPS must be taken out of service for maintenance or an internal failure, the static switch shall transfer the load to the alternate source without an interruption. Re-transfer of the load shall be accomplished by synchronizing the UPS to the alternate source, paralleling the inverter with the alternate source, and then disconnecting the alternate source.

2.8.4 Downgrade Mode: If the battery must be taken out of service for any reason, it shall be disconnected from the rectifier charger and inverter by means of a circuit breaker. The UPS shall, upon receipt of a remote signal, open the battery circuit breaker and isolate the battery from the UPS system. Remote opening of the battery circuit breaker shall activate an individual battery circuit breaker alarm and the summary alarm. The UPS shall continue to function and meet the performance criteria specified except for the protection time specified. If there is a loss of input power to the module when the battery has been disconnected, the logic shall immediately isolate the module by opening the output breaker or contactor to prevent a reverse power condition.

2.9 Short Circuit Withstand.

2.9.1 The inverter shall be able to sustain a short circuit current across its output terminals, of 300% of its rated output for one cycle, after which it shall current limit to 150% until the fault clears or the UPS system transfers to bypass.

2.9.2 Inverters shall be provided with short circuit protection circuitry such that in the event of a direct short at the UPS system output it will current limit and attempt to clear the fault. The module shall have the capability to isolate itself fast enough from the output bus so that the reverse power into the fault from the bypass line will not cause the entire UPS output to collapse below the acceptable limits for the operation of the computer load as defined by the Information Technology Industry Council (ITIC) Curve. At the Governments option this feature will be demonstrated at the factory by shorting the output of the inverter to ground and monitoring the UPS output bus. However, if the fault is sustained and the UPS system is unable to transfer to bypass due to unavailability of bypass power, inverters shall shut down in a controlled manner without damage or blowing fuses, followed by tripping of module output circuit breakers. All inverters shall then power up automatically (without operator intervention) and be ready for reconnection to the module bus by manual closure of module output breakers. At the Governments option this feature will be demonstrated at the factory by prohibiting the static bypass function (bypass breaker drawn out of connected position) and subjecting the UPS system output to a three phase short via a three phase contactor connected to all three phase buses.

2.9.3 The UPS shall be listed as meeting the parameters of UL Standard 1778, and bear the UL label.

2.10 System AC to AC Efficiency: The UPS AC to AC minimum efficiency at rated input and output voltage is 89%, at 100% linear load, nominal input voltage, with batteries fully charged.
