3.4 Power supply
Battery
•
Lithium battery, 3.6 V, C size, 8.5 Ah
• Battery connection is polarity protected
• The battery lifetime depends on transmitter settings. (typical
battery life is 1-2 years from installation)
• Current consumption < 100mA *)
External supply voltage
• Transmitter can be powered from external 12 or 24 V DC
supply
• Supply voltage range 9 . . . 40 V
• External power supply is galvanically isolated from inputs.
Isolation voltage between supply/inputs is 1500 Vrms
• Inputs are not isolated among each other!
• Current consumption < 70mA *)
*) Current consumption is affected by the transmission interval, connected sensors and the quality of the radio
connection between the transmitter and the gateway. Typical current consumption is 0,5…50 mA.
