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.
Loosen the lid clip and remove the enclosure cover to access connectors and electronics.
