The Challenge: Distributed UPS Systems
UPS systems are often scattered across floors or buildings. Pulling cables from each UPS to a central BMS is costly and disruptive. Wireless Modbus bridges make retrofits fast and reliable.
What You Can Monitor
Electrical
- Input/Output Voltage and Frequency
- Load (kW, %)
- Runtime Remaining
Battery
- Battery Voltage and Current
- Temperature
- State of Charge (SOC)
Status & Alarms
- On Battery / On Mains
- Buzzer, Overload, Replace Battery
- Fault codes
Wiring Diagram
Connect UPS RS-485 to Link485 gateway using A/B terminals. Data is sent wirelessly to cloud or BMS.
Case Study: Server Room UPS Fleet
12 UPS units across 3 floors
Facility IT deployed Link485 Air on each floor and connected all UPS units over RS-485 daisy chain. No new cabling from floors to BMS. Alerts and reports enabled within a day.
