The advanced
design Spectron LSN System utilizes PWM technology to provide 100%
compatibility with all connected life safety loads. "No Break" sinusoidal
output assures that even voltage-sensitive or frequency-sensitive loads will
operate normally during emergency operation. Utilizing the latest IGBT
(insulated gate bipolar transistor) technology, the Spectron LSN has an
AC-in to AC-out efficiency of 98%. Self diagnostics, reduced maintenance and
greater reliability make the Spectron LSN the most innovative inverter
system on the market today.
|
Interruption-Free Power |
 |
Spectron
LSN Provides continuous power to all critical life safety loads and
other secondary support systems. This "no break" switching between
utility and inverter power means that all connected equipment will
continue to operate normally under emergency conditions. |
|
Voltage
Regulation |
|
|
Spectron
LSN's Boost Tap Regulation protects your loads from "brownouts" and
recurrent low-voltage transients by sensing any drop in voltage and
"boosting" the voltage back up to nominal without drawing from the
batteries and shortening their lives. |
|
Mixed
Loads |
 |
Spectron
LSN's "no break" design provides continuous operation to mixed loads
regardless of power factor. Capacitive, inductive or resistive loads
will operate normally as will voltage-sensitive or frequency-sensitive
equipment. |

Features
The Spectron LSN Life Safety
Network is designed
to provide:
- A simplified system approach to emergency lighting and power
- "No break" power
- Pulse width modulated technology
- 100% load compatibility
- Maximized reliability
- Reduced maintenance expense
- Enhanced security
- Improved building aesthetics
- Minimized space requirements
- Communications capability
Most importantly, it delivers optimum safety for building occupants.
Advanced Design
The basic elements of an inverter system are batteries, an inverter, a charger
and a transformer. Spectron LSN, however, is unlike traditional IPS, FT or UPS
systems because of its innovative design.
This pulse width modulated (PWM) high-frequency inverter utilizes the latest
IGBT (Insulated Gate Bipolar Transistor) technology. The AC-in to AC-out
operating efficiency is 98%, well above other central inverter system equipment.
Communications
All Spectron LSN inverter systems are equipped with an RS232 communication
interface designed to give the user greater flexibility in monitoring and
controlling the system.
Big Performance...Small Footprint
Spectron LSN inverter system’s feature-rich design is provided in an incredibly
compact package. Spectron LSN system capacities under 5KVA require less than
four square feet of floor space; all other systems up to 15KVA require less than
eight square feet - the smallest footprints in the industry!
Compatibility
Spectron LSN systems provide 100% compatibility with all connected loads. “No
break” sinusoidal output assures that even voltage-sensitive or
frequency-sensitive loads will operate normally during emergency operation.

operation by unauthorized personnel
Application/Installation:
Field Support
During or after installation, our Systems Service Department is available to
provide expert assistance. Our service representatives are available to answer
customers’ questions or solve their problems.
Toll-Free Number
A toll-free phone has been set up for Spectron LSN service questions. The number
is: 1-800-848-6439 For our customers’ convenience, this phone number is printed
on the inside of the unit’s cabinets.
Application Support
Dual-Lite’s representatives provide application assistance and customer support
to meet your needs. Through training, technical support literature and the
assistance of factory application engineers, representatives will work with the
engineer and end-user to select the proper system.
Factory Start-Up (FS)
Factory Start-Up is designed to insure proper operation and installation of the
Spectron LSN inverter system. It provides for a highly trained
factory-authorized technician to administer an on-site, point-by-point visual
check of the system. Included is a check of all internal electrical connections,
AC and battery connections, system voltages and all system operating parameters.
The system is then powered up and all system parameters are tested, calibrated
and recorded. The technician will also perform a battery discharge test to
insure proper battery capacity. If any malfunctions are detected, the technician
will remedy them while on site (depending on the availability of parts), or make
arrangements to do so. The technician will instruct on-site personnel about the
operation and maintenance of the equipment. Warranty of the equipment will
commence on the start-up date.
Service Agreement (SA)
Provides for an annual visit by a factory-authorized technician to test all
system options and related accessories. Technician will perform a physical and
mechanical inspection of all batteries and battery connections. Included will be
a test, calibration and recording of the system charger output, battery float
voltages and all input/output settings. Technician will also perform a simulated
power outage, discharging the batteries to 87.5% of nominal voltage and record
readings of individual battery voltages.
Monitoring Program (MP)
Requires Factory Start-Up (FS) and Fax Modem (FAX) options. It provides for the
continuous monitoring of the equipment by our Technical Support Group. All
monthly and yearly system tests will be reviewed and analyzed for early warning
signs of system malfunctions. Any failures will be automatically relayed to our
Service Department where corrective action can be taken. This Monitoring Program
is the only automated failure reporting system in the industry. It requires a
dedicated analog telephone line, to be provided by the customer.
Spectron LSN Features
Spectron LSN System
Features and Design
Features
A solid-state charger
transforms the incoming utility voltage into a regulated DC supply
voltage to charge the batteries.
A maintenance-free battery is provided on standard models to maintain
power to the inverter. The batteries are fitted with a suitably rated DC
switch and fuse to provide overload and short-circuit protection and
also allow isolation from the system for maintenance purposes.
A high-frequency, pulse width modulated inverter transforms the battery
energy into low-distortion, no break, sine wave AC voltage to supply the
emergency load.
90% boost tap for line regulation protects against brownouts and
conserves batteries for emergencies.
