NETWORK EQUIPMENT · BACKUP POWER
Multi-output
UPS
Power network equipment in lift calling systems. Match voltage, current and connectors for media converters, switches and other loads, then confirm the battery configuration and required backup duration.
Prepare backup power around the network loads
The source description names 5V media converters and 9V switches as uses. Match each actual device’s nameplate and connector requirements individually.
Load side
List the network devices that need power, recording voltage, operating current, connector and polarity for each.
Power-supply side
Confirm the supply and battery configuration against total load, installation conditions and backup requirements, including output-current allocation.
