PART 2 - PRODUCTS

MANUFACTURERS
A.
2.2
In other Part 2 articles where titles below introduce lists, the following requirements apply to product selection:
1.
Manufacturers: Subject to compliance with requirements, provide products by one of the manufacturers
specified.
PERFORMANCE DESCRIPTION
A.
Automatic operation includes the following:
1.
2.
3.
4.
5.
6.
7.
8.
9.
Normal Conditions: Supply the load with ac power flowing from the normal ac power input terminals,
through the rectifier-charger and inverter, with the battery connected in parallel with the rectifier-charger
output.
Abnormal Supply Conditions: If normal ac supply deviates from specified and adjustable voltage,
voltage waveform, or frequency limits, the battery supplies energy to maintain constant, regulated inverter
ac power output to the load without switching or disturbance.
If normal power fails, energy supplied by the battery through the inverter continues supply-regulated ac
power to the load without switching or disturbance.
When power is restored at the normal supply terminals of the system, controls automatically synchronize
the inverter with the external source before transferring the load. The rectifier-charger then supplies
power to the load through the inverter and simultaneously recharges the battery.
If the battery becomes discharged and normal supply is available, the rectifier-charger charges the battery.
On reaching full charge, the rectifier-charger automatically shifts to float-charge mode.
If any element of the UPS system fails and power is available at the normal supply terminals of the
system, the static bypass transfer switch switches the load to the normal ac supply circuit without
disturbance or interruption.
If a fault occurs in the system supplied by the UPS, and current flows in excess of the overload rating of
the UPS system, the static bypass transfer switch operates to bypass the fault current to the normal ac
supply circuit for fault clearing.
When the fault has cleared, the static bypass transfer switch returns the load to the UPS system.
If the battery is disconnected, the UPS continues to supply power to the load with no degradation of its
regulation of voltage and frequency of the output bus.
