Item # DLS-750, SYNCHRON Small Single-Phase Inverter

The Synchron single-phase inverter series provides true sine wave emergency power in ratings from 400 to 21 OOVA/Watts. Featuring true 'no-break' switching between utility and inverter power, all connected equipment will continue to operate normally under emergency conditions. The system mounts indoors and powers indoor or outdoor fixtures arid other critical loads.

OFFLINE TECHNOLOGY - Continuously monitors input power conditions allowing the unit to operate with 98% efficiency translating to lower operating costs.

HID COMPATIBILITY - An instantaneous and synchronized transfer of power from normal to emergency mode ensures compatibility with HID lamp sources.

TRUE SINE WAVE OUTPUT - Sinusoidal waveforms yield less distortion and assure that voltage sensitive or frequency sensitive loads will operate normally during operation.

PULSE WIDTH MODULATION - High frequency digitally generated output waveform that results in greater efficiency, less heat, quieter operation and lower operating costs all within a compact design.

SMALL FOOTPRINT - The Synchron inverter system has one of the smallest footprints in the industry - less than 3 square feet! The small cabinet may be wall mounted.

GENERATION II STATUS & CONTROL INTERFACE - Three multipurpose LED indicators provide a simple, intuitive interface to notify the user of operating status as well as visual service alerts to operational malfunctions should they occur.

Advantages of a Central Lighting Inverter System

Full Lumen Output

Occupants feel more at ease and are less likely to panic when emergency lighting is provided by existing luminaires. Central lighting inverters power designated luminaires to full lumen output during a power outage ensuring a bright, evenly illuminated path of egress in emergency situations.


Using existing luminaires allows occupants to enjoy the original architectural intent and integrity while simultaneously satisfying life safety requirements.

Ease of Installation

In most installations a single central lighting inverter will provide code required power to the emergency lighting vs multiple fluorescent battery packs or unit equipment. This reduces the amount of time and labor required for initial installation.

Ease of Maintenance

With a centrally located inverter system there is only one location for maintenance vs unit equipment which is located throughout the building, reducing maintenance time and labor costs.

HID Compatibility

Luminaires using HID lamp technology are often selected for a given lighting system because of their energy efficiency, long life and tolerance to high or low ambient temperatures. However, HID lamps are susceptible to voltage drops and have long re-strike times that could exceed life safety code requirements. Where HID luminaires are in use or being considered, an uninterruptible central lighting inverter is the ideal choice as an emergency AC power supply, even when an engine generator set is installed by code requirement. An uninterruptible power supply ensures voltage- sensitive loads, such as HID lamps, will operate normally as power transitions from utility power to emergency battery power to emergency generator power and back to normal utility power.

Outdoor Applications

In the absence of lighting due to an interruption in the normal power supply, the Life Safety Code calls for illumination of an egress pathway to safely guide building occupants to a "public way." Some Authorities Having Jurisdiction CAHJs) will interpret a "public way" to include luminaires in outdoor applications. Inverters can remain located inside the building so cold or wet conditions that can impact performance, cost or life of the product are eliminated.

Area of Coverage

The ability to generate the required level of illumination in large venues, such as stadiums or gymnasiums, is beyond the capability of most emergency lighting unit equipment. A properly sized central lighting inverter powering existing fixtures at full light output is the logical choice for these applications.

Auxiliary Critical Loads

In addition to providing emergency AC power for lighting loads, a central lighting inverter can also be used to provide emergency power for other critical equipment such as:
• Fire detection and protection equipment
• Climate control systems
• Directional egress systems
• Patient care support functions
• Building management systems
• Security systems
• Automated door mechanisms
• Communications equipment

Total Cost of Ownership

Dual-Lite realizes the initial price of an emergency lighting system is only one consideration when evaluating the total cost of ownership when comparing a centralized vs a decentralized emergency lighting system. Energy costs to operate the unit and annual maintenance expenses can significantly add to the total cost of ownership. Incorporating a central lighting inverter into your emergency lighting system will typically reduce your operating and maintenance costs to yield the lowest overall total cost of ownership. By incorporating energy efficient designs and intuitive interfaces with the latest in remote communications technology, Dual-Lite central lighting inverters are designed to lower the total cost of ownership ; even further.
