Digital Energy LP Series g 2 - Introduction 2.1 Description More than ever before, today's advanced electronic equipment, with complex integrated circuits and other sensitive electronics, needs a stable and continuous AC power supply to operate correctly. While the power coming from the wall outlet is often unreliable, a GE Digital Energy LP-U UPS provides the security of completely uninterrupted power. A compact, truly on-line system, the LP-U UPS protects your equipm

Digital Energy LP Series g 3 - Functional Explanation 3.1 The Principles of Operation The UPS stores electric energy in batteries. This allows the UPS to supply output power even when the incoming utility power is cut off completely. Energy is stored as Direct Current (DC), while input and output energy must be Alternating Current (AC). Therefore the UPS contains an input converter (AC to DC) and an output converter (DC to AC). (fig.2) 3.2 Normal Conditions Under norm

Digital Energy LP Series g 3.4 Automatic Bypass Switch If the output converter is unable to deliver the demanded output power because of overload or overtemperature, the automatic bypass switch will automatically transfer the load to the utility. When the situation is corrected the UPS will switch back to normal operation, i.e. the load is tranferred back to the output converter. Though the automatic bypass switch is shown as a simple mechanical switch in figures 2-5, the transfers a

Digital Energy LP Series g • Ensure that the total power requirement of the equipment to be protected does not exceed the rated output power of the UPS. (output power for your unit is indicated on the rating label on the rear panel). • When using the 120V split phase outputs make sure that the load per 120V output does not exceed half the rating. • The UPS may only be installed by trained personnel. The UPS must be grounded when in use: Connect the UPS to a single phase, three
