UPS MODULE STANDARD FEATURES
The UPS module shall consist of the following standard components:
A.
Rectifier/Charger: The rectifier/charger shall convert incoming AC power to regulated DC
output for supplying the inverter and for charging the battery. The rectifier/charger shall
be a high-frequency PWM design, using Insulated Gate Bi-polar Transistors (IGBTs). The
modular design of the UPS shall permit safe and fast removal and replacement of the
rectifier/charger module. Mean time to repair (MTTR) for the module shall be no more
than 30 minutes in order to return UPS to normal mode. The rectifier/charger module
shall also provide the following:
1.
The rectifier shall be capable of drawing power from the utility with a power factor
of 0.99 under nominal conditions.
2.
The rectifier shall feature protection circuitry that prevents the IGBTs from
sourcing current in excess of their published ratings.
3.
An option shall be provided to allow the rectifier to be capable of operating from a
delta transformer output or high impedance grounded transformer (480V systems
only).
B.
Inverter: The inverter shall feature an IGBT pulse-width-modulation (PWM) design with
high speed switching. The inverter shall also have the following features:
1.
The inverter shall be capable of providing the specified quality output power
while operating from any DC source voltage (rectifier or battery) within the
specified DC operating range.
2.
The modular design of the UPS shall permit safe and fast removal and
replacement of the inverter module. Mean time to repair (MTTR) for the module
shall be no more than 30 minutes in order to return UPS to normal mode.
3.
The inverter shall feature protection circuitry that prevents the IGBTs from
sourcing current in excess of their published ratings.
C.
Static Bypass: The bypass shall serve as an alternative source of power for the critical
load when an abnormal condition prevents operation in normal mode. The bypass shall
consist of a fully rated, continuous duty, naturally commutated static switch for high-
speed transfers. The bypass shall feature the following transfer and operational
characteristics.
1.
Transfers to bypass shall be automatically initiated for the following conditions:
a)
Output overload period expired.
