1600XP Series Single Phase Uninterruptible Power Systems
Product Specifications –Rev 5.0 October 2013
3.6kVA –22kVA
1.0 Scope
This specification document describes the Toshiba 1600XP Series. The 1600XP is continuous
duty, single-phase, on-line, solid-state uninterruptible power supply system hereafter referred to
as the UPS. The UPS will supply a clean regulated AC power output sine wave which is
unaffected by the quality of the AC input. The input and output voltages are single phase.
2.0 General Operation
Under normal operating conditions, the UPS' rectifier converts alternating current AC power to
direct current (DC) power, which is required for the system's inverter and battery charger. The
charger supplies regulated DC power to keep the batteries constantly charged. The inverter uses
pulse width modulation (PWM) that fully utilizes the characteristics of insulated-gate bipolar
transistors (IGBT) to convert DC power to regulated AC power. Therefore there is a constant
supply of power. The batteries will instantaneously supply the inverter DC power when on AC
power line failure occurs.
2.1 Performance Standards
The UPS is designed in accordance with and is compliant with the following sections of the
current revisions of the following standards:
-ANSI C62.41 (IEEE 587) –Standard for Surge Withstand ability
-UL 1778 (CUL)
-CE
-FCC Class A
-National Electrical Code (NFPA-70)
-NEMA PE-1
-OSHA
-ASME
-ISO 9001, 14001
-RoHS

3.3 Assembly

4.0 System Theory, Modes of Operations and Main Components Functions
4.1 Theory
AC input from the utility system is converted into DC power. The stepped up DC power is then
converted to AC power by the inverter. The output voltage waveform of the inverter will be the
pulse voltage waveform modulated by the PWM control. The PWM-Modulated voltage
waveform is transformed into a sine voltage waveform by the inductive component of the
inverter inductor and by the capacitive component of the capacitor filter. The chopper, inverter,
and charger use IGBT’s that has a high switching speed.
4.2 Modes of Operation
The UPS operates as an on-line, fully automatic system in the following modes:
A. NORMAL - Incoming AC power is boosted using a chopper circuit, and converted into DC
power. The DC power is then used to charge the battery bank while at the same time providing
clean DC power to the inverter circuitry. The inverter converts DC power to a clean regulated
AC power which feeds the load.
B. BATTERY - Upon failure of commercial AC power, the UPS derives power from the battery
bank and continues feeding the load with clean regulated AC power. There is no interruption to
the critical load upon failure or restoration of commercial AC power.
C. RECHARGE - Upon restoration of the commercial AC source, the rectifier/chopper powers
the inverter while simultaneously recharging the battery bank. The UPS recharging process:
a) A constant level of current is used to recharge the batteries. The process utilizes a
current-limit function to prevent overcharging batteries, thus extending the life of the
batteries.
b) As the batteries reach the normal charge level, a constant-voltage control begins which
causes the battery recharge current to gradually decrease.
c) Under normal operation, the UPS battery bank "floats" at the 2.25-2.27 volts per cell DC
level to stay fully charged and ready for the next discharge.
D. BYPASS MODE - Upon detection of an internal fault or output overload, the UPS
automatically switches from inverter power to an internal bypass via the static switch. Transfer
is within 4 milliseconds, causing no interruption to the critical load. While in bypass, the UPS
protects against spikes and common/normal mode noise by utilizing line filters and an output
isolation transformer. “Return from Bypass mode” is an automatic function, which does not

interrupt the critical load. Transfer to Bypass may also be performed as a manual operation via
the UPS touch screen front panel.
E. POWER CONDITIONING MODE - Should the batteries be removed from the UPS, the UPS
continues to function and still provide protection against spikes, common/normal mode noise,
load steps and frequency shifts (without battery back-up capability).
4.3 Main Components Functions
4.3.1 Converter / Charger / DC Chopper
DESCRIPTION - The converter/charger consists of a solid-state three phase rectifier, DC
to DC converter (chopper), output filter, and transient suppresser network to regulate and
maintain DC power to the inverter.
1) TRANSIENT SUPPRESSER - The incoming AC utility connects first to a molded
case circuit breaker as a means of disconnecting power to the UPS. Power flows through
a surge absorber to prevent large transients from passing through to the load or damaging
the batteries. Power flows through a line filter to prevent sags or surges from passing to
the load.
2) CONVERTER/CHARGER - The converter serves to change incoming AC power to
DC, which is supplied to the DC chopper. From this point, DC power is used to recharge
the battery bank while simultaneously providing power to the inverter.
a) Input Frequency Range: 45-65 Hz, continuous, without battery operation
b) Capacity: Battery recharges to within 90% of nominal from a fully discharged
state in 10 times the discharge time.
3) DC CHOPPER - The chopper circuit consists of inductors, capacitors, diodes and
IGBT's (Insulated Gate Bipolar Transistors). The chopper provides start-up protection
(by checking phase rotation of incoming utility power), boosting the DC to the inverter
during low AC input voltage conditions, providing power factor enhancement, and
reducing reflected harmonics to incoming utility power.
4.3.2 Pulse Width Modulated (PWM) Inverter
DESCRIPTION - The PWM (Pulse Width Modulated) inverter incorporates an advanced
IGBT design and output over current protection for clean, regulated output power to the
critical load.
1) INVERTER - The inverter network consists of a high speed IGBT switching network
designed to supply non-linear loads with a clean and steady voltage waveform. The
inverter switching speed is fast enough to limit audible noise to 50 dBA at 3 feet
(measured on ‘A’ scale).
2) OVERCURRENT PROTECTION - The output circuitry is equipped with a Hall
Effect Current Transformer to detect and protect the inverter from excessively high
currents.

4.3.3 Static Bypass Switch
1) TRANSFER - The static bypass switch consists of thyristor switches in conjunction
with an output contactor to permit manual switching from bypass to UPS and UPS to
bypass without power interruption. The UPS instantaneously transfers to bypass should
a component fail during normal operation (provided the UPS and bypass are in
synchronization). Auto-retransfer to UPS after an overload condition is completed
within one second after the bus has dropped to 100% of nominal.
2) REMOTE RUN/STOP - A set of normally open dry contacts are provided to remotely
transfer the UPS on-line and off-line. When the UPS is in this mode of operation, the
UPS front control panel is disabled to provide a secured configuration.
4.3.4 Microprocessor Control System
1) DESCRIPTION - The UPS system is provided with a microprocessor internal control
system to perform start-up, transfers, monitoring, and battery recharging. The
microprocessor provides information to the user (via a touch screen liquid crystal display
with searchable menu tree) such as system status, fault messages and input and output
parameters.
2) LED INDICATORS - The following LED indicators are provided on the UPS front
panel displays, which mimic power flow through the UPS:
a) AC INPUT (Green Lamp) - Lights when normal AC input power is being
supplied to the unit.
b) WARNING (Amber Lamp) –Lamp is OFF when the UPS is normal.
c) ON-LINE FAULT (Green/Red Lamp) –GREEN when voltage is within
specifications, and RED when voltage is out of specifications
3) SYSTEM METERING - The UPS is provided with a touch screen display which can
display current system operation, monitor current operating mode, performance settings,
or fault/ incident records.
4) SYSTEM DIAGNOSTICS - Should a fault occur during operation, diagnostic
information is displayed in the lower left corner of the touch screen.
5) Battery Test Function
The UPS is provided with a “Battery Test” pushbutton to periodically check the
condition of the batteries. Upon detection of a battery problem, the UPS shall notify the
user of this condition allowing the user to perform a detailed check of the battery string.
