    -40°C to 10 K above max. ambient temperature. Signal amplifier/power supply SITRANS LC300 uses a switched power supply circuit that makes the most efficient use of the available power present on the terminals. If the signal current is low (4 mA), the terminal voltage will increase due to a voltage drop of other components in the loop, and if the signal current is high (20 mA), the terminal voltage will decrease.
