1. INTRODUCTION
1.1. GENERAL
The principles of operation described herein are applicable to all models. The DSPM, Inc. Micro Elite Emergency Lighting
Inverters are manufactured to provide critical power for lighting during a power outage. The Micro
life safety codes of UL924 and UL1778. These codes were established to allow the emergency lighting inverters to provide
critical power to the lighting circuits during a power failure. The emergency lighting inverter will then provide power for 90
minutes that will allow safe and orderly evacuation from the facility.
The product is an advanced Emergency Lighting Inverter System based on Intelligent Microprocessor Control. The Emergen-
cy Lighting Inverter System is an intelligent protector and provides pure, reliable AC power to the emergency loads – protect-
ing them from utility power blackouts, swells, sags, surges and interference. All types of lamps are supported by our lighting
inverter.
Under normal power conditions, this design enables the system to adjust and filter power fluctuations continuously and auto-
matically. In the event of a power failure, it can immediately provide back-up power from the batteries without any interruption.
When the utility power is connected or reconnected, the charger will automatically recharge the batteries.
When input power to the Micro Elite is lost during a power outage, the system will automatically draw power from its internal
battery supply without any interruption. The critical load will receive only clean sine wave power. The internal VRLA (valve
regulated lead-acid), maintenance-free batteries provide 90 minutes of backup power.
Upon restoration of input power, the Micro Elite automatically resumes normal operation, and immediately begins to recharge
the batteries. The Micro Elite has an internal bypass circuit, which maintains the power to the load in case of internal UPS
failure.
The Advanced Battery Management system in this unit uses a Digital Signal Processing/Pulse-Width Modulation (DSP/PWM)
Smart Battery Monitoring System for managing the system batteries. The DSP/PWM Smart Battery Monitoring System is
temperature compensated resulting in maintaining maximum runtime and battery life. The microprocessor controls recharge
and the DSP/PWM offer overcharge protection.
The Micro Elite Online Emergency Lighting Inverter incorporates double-conversion technology that provides perfect protec-
tion specifically for Egress Lighting for facilities. It is designed to provide continuous and clean electrical power to a critical
load. The load is powered by the inverter, which receives its power from the building source. In the event of an input power
failure, the UPS will supply power to the critical load for the specified battery time.
The inverter uses of a double-conversion principle eliminates all sources of unwanted power disturbances. A rectifier converts
the alternating current from the building source to Direct Current (DC). This DC charges the batteries and powers the inverter.
With the basic DC voltage, the inverter generates a sinusoidal alternating current (AC) voltage, which continuously supplies
the load. In times of power outrages, the 90-minute backup time that come standard in our units keep the load energized.
If the input power is not restored promptly, backup power from the UPS battery permits the orderly shutdown of equipment
supported by the UPS. The UPS is simple to start up, operate and maintain.
The Micro Elite is an Stand-By PWM inverter available in multiple output rating. It is listed for compliance to UL1778, UL924,
UL924A and CSA107.1 standards. The Micro is available with a variety of input or output voltages and power configurations.
