POWER SUPPLY EMERGENCY POWER SUPPLY

In the event of a power grid outage, the backup power supply maintains voltage in the line segment using a separate 12V lead-acid battery. When the power grid is operational, the backup power supply charges and maintains the battery charge. The operating state of the backup power supply can be read via a binary input (grid voltage supply, alarm, battery voltage supply). Nominal voltage: AC 110-230 V ±10% Operating voltage: min. AC 92 V - max. AC 253 V Power grid frequency: 50-60 Hz ±10% Output for KNX power supply via backup current: Output voltage: DC 30 V ±2 V Output current: grid power only, no battery max. 300 mA; battery only, no grid power max. 640 mA Backup operation time with 7.2 Ah battery: 640 mA: approx. 0.5 h 320 mA: approx. 1 h 160 mA: approx. 2 h Backup operation time with 18 Ah battery: 640 mA: approx. 1.25 h 320 mA: approx. 2.5 h 160 mA: approx. 5 h Charging current: max. 1 A Device width: 4 modules = approx. 72 mm This product description is an automated translation of the original Finnish description.
