Power Quality Monitoring

Field bus componentsPowerToStore 10F – mini UPS for UMG 604ECapturing short-term interruptions is one of the strengths of the UMG 604/605/508/511. Due to the small constructionand the large memory, the instrument is ideally suitable for monitoring transformer stations. The UMG 604’s auxiliaryvoltage supply is provided through a switch mode power supply which has been developed for both DC and AC operation.Voltage interruptions of approximately 80ms are safely bridged. Voltage interruptions which are longer than 80 ms causethe UMG 640E to shut down. In order to capture longer short-term interruptions, the auxiliary voltage supply of the UMG604 must be backed up with a UPS. If a UPS is not available, the PowerToStore will be used. Usually batteries are used inUPS units. However, the disadvantage of batteries is the regular maintenance. The PowerToStore 10F is an energy bufferbased on capacitors. Therefore it does not require batteries and is maintenance free. The capacity level has been designedso that 3 x UMG 604E can be supplied with energy for approximately 3.5 minutes. The maximum number of UMG 604swhich can be connected is limited to 3 instruments.Technical data Potential separation: yes Input voltage: max. 240V AC (DC) Output voltage: ca. 220V DC Output current: max. 90mA Storage capacity: 10 farad Dimensions (WxHxL): 220 x 105 x 80 mm Cable connections: screw/plug clamps Mounting: fixing on din rail Housing: aluminium mould housing Operating temperature: -25° … +55°C Lifespan: ca. 15 to 20 years at 40°C Degree of protection: IP54 Weight: 1.5 kg Item number: 15.06.400ApplicationUMG 604 UMG 604 UMG 604190
