UPS/NTA GB/DELMP_EXPC1C3C6_B 6
1.1 SCOPE
This document provides required information for operating DELPHYS MP and DELPHYS MP
elite systems. It describes the facilities offered on the control panels:
- Scrolling through the menus displayed
- Load transfer onto the automatic and/or maintenance bypass
- System start up or shutdown
The operating instructions refer to the most frequently used configurations, i.e.:
- Single UPS’s with bypass
- Modular systems
- Central bypass systems
1.2 PURPOSE AND UPS COMPOSITION
DELPHYS MP and DELPHYS MP elite provide:
- very low distortion and high power factor to the upstream power supply,
- voltage and frequency stability as well as continuity of supply to downstream loads –whatever
the outages or disturbances on the upstream power supply-.
The system is fitted with double conversion VFI-SS-111 technology.
When the input power supply is present, the UPS acts as a stabilizer. In the event of a utility
outage, it acts as a source of electrical power. In such case, the required power is supplied by
the battery, which is kept charged when the mains is present.
DELPHYS MP and DELPHYS MP elite provide three-phase sinusoidal output. The UPS is
composed of:
- 1 fully controlled three-phase rectifier with 6 thyristors or IGBT (DELPHYS MP elite),
- 1 three-phase inverter of S.V.M. type (Space Vector Modulation),
- 1 static bypass to transfer the load automatically and without interruption to the bypass
supply.
- 1 maintenance bypass, which allows a seamless load transfer to the mains during
maintenance operations,
- 1 battery,
- 1 control panel made up of a mimic panel, an 8-line display and an intuitive user interface.
