Consumption Ever

Milesight UR41 is designed to operate on limited power sources through advanced power management, which make it an ideal battery-powered and solar-powered applications

  • Typical: 226mA
  • Maximum: 260mA

*Power consumption calculation based on 12V rated voltage

**Power consumption may vary under different operating environment and conditions

***Typical power consumption calculation based on cellular network and IPC

Advanced Power Management
with Less than 1 Watt in Idle Mode

  • Power consumption as low as 60mA in idle mode
  • Fast network response from standby mode triggered by timers, DI, Cellular, Ethernet or serial port
  • Protect power sources by dropping power consumption to a target of 6.3mA in standby mode

*Power consumption calculation based on 12V rated voltage

**Power consumption may vary under different operating environment and conditions
