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 UPS provides the security of
completely uninterrupted power.
A compact, truly on-line system, the LP UPS protects your equipment from all forms of power interference,
including complete power failure. A simple and elegant circuit design, together with extensive protection against
abnormal operating conditions (e.g. overload, short circuit, overheating), makes the LP UPS exceptionally
reliable.

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 normal conditions, energy from the utility is channelled through the input converter, which supplies the
output converter and the battery charger. The batteries are kept in a fully charged state, and the output
converter synthesizes a completely new AC output sine wave to supply the load (electrical equipment).

3.3 Utility Failure
In the event of a utility power failure (i.e. absent or outside tolerance) the system uses the energy reserve
stored in the battery to continue to produce AC power, ensuring unbroken output (fig. 3). No interruption or
alteration will ever be noticed in the output power.
In the event of an extended utility failure, the output converter will stop when the battery has been discharged.
At this point, the UPS is no longer able to power the connected equipment.
When the utility is re-established within tolerance, the output converter will restart automatically (if stopped, see
above) and will be supplied again by the input converter. The batteries will be recharged, making them ready to
support future power failures.

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 transferred back to the output converter. Though the
automatic bypass switch is shown as a simple mechanical switch in figures 2-5, the transfers are done by
means of thyristors, i.e. electronically, without any interruption of the power supplied to the load.
In case of a severe overload or short-circuit the magnetic bypass circuit breaker (rear panel) may trip in order to
protect the UPS. If the current is insufficiently high to trip the breaker, the UPS will be switched off by the
software in order to protect the UPS and connected equipment.

Figure 4. Bypass operation: automatic bypass
If a power failure occurs during bypass operation, load power is lost. If the UPS functions under overload
conditions it may not be able to protect the load.
3.5 Manual Bypass Switch (Service switch)
The system can be bypassed manually using the manual bypass switch located at the rear panel. It is a twoposition switch: the normal position is '1': as in figures 2-4. Position '2' is the service position: the load is directly
connected to the utility input. This way maintenance of the UPS (e.g. battery replacement, as in fig. 5) is
possible without interruption of the power supplied to the load.
CAUTION: REFER SERVICE TO QUALIFIED PERSONNEL ONLY.
