Energy Consumption

Efficiency: 92-94% (double conversion mode) Bypass Supply Static Bypass Mains Supply AC DC Rectifier DC Inverter AC Output Filter Battery Bank •

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

7 / GE Consumer & Industrial / September 2004

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 Bypass Supply

Static Bypass • •

Mains Supply charged

AC DC Rectifier

Load is supplied via the bypass The rectifier keeps the batteries

DC Load AC Inverter Output Filter Battery Bank •

The inverter is switched off (no heat losses)

Performance of ECO Mode

Simulation of transfer back to inverter Fast Transfer to Inverter

< 2ms Output voltage Bypass on/off Inverter current 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%

Back feed protection

back feed protection

Bypass Static Bypass Mains AC DC Rectifier DC AC Inverter 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 EN62040-1 (UPS safety)

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 62040-2 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
