The output voltage is newly generated, independently from the input voltage.
Voltage and frequency variations at the input are not present at the output.
Heat losses are present in Rectifier and Inverter

8. ECO Mode
Supply the load via the bypass circuit in order to prevent heat losses. This can be done only in case the bypass supply is in tolerance

Load is supplied via the bypass
The rectifier keeps the batteries charged
The inverter is switched off (no heat losses)

9. Performance of ECO Mode

Inverter control
In case the bypass supply is out of tolerance the inverter will start immediately
This transfer is done within 2 ms, which is more than sufficient for most loads
Bypass supply voltage tolerance: +/- 10% (adjustable)
Bypass supply frequency tolerance: +/- 5% (adjustable)
Efficiency up to 98%

10. RPA Redundant Parallel Architecture
LP Series is a cost effective and reliable UPS system, using proven technology
To increase system reliability more units can be connected in parallel with GE‘s unique RPA concept
RPA features
Up to 4 units in parallel
Any UPS able to be the logic leader
Decentralized bypass
No single point of failure
Utility Supply
To critical load

Back feed protection: preventing feedback to the mains from the
inverter in case of mains failure and a fault in the bypass circuit
It provides a safer environment for end users and engineers
GE provides back feed protection as a standard. Others as option
Backfeed protection is mandatory according to EN (UPS safety)

13. Electro Magnetic Compatibility IEC 62040-2 Class A
Emission
All electronic equipment emits electromagnetic waves through cables (conducted) and air (radiated)
Immunity
All electronic equipment is sensitive for electromagnetic waves. These waves can disturb the function of this equipment
Electro Magnetic Compatibility
Different types of equipment (all emitting electromagnetic waves) can work properly even when installed close to each other. They are compatible
IEC is a standard that defines the limits of maximum allowable levels of emission of electromagnetic disturbances for UPS systems
This certifies the proper functionality of a UPS system and other equipment close to in the environment

14. Electro Magnetic Compatibility IEC 62040-2 Class A
LP 33 complies to IEC Class A
