AL45DLL “long life” with polymer-filled
Applications
4–20 mA loop power supply
with current limiting (transmitter protection)
Hart protocol, very low noise
These power supplies are available with 1 to 8 outputs and are particularly well-suited for implementing converters in a two-wire technical
(powered by the 4–20 mA loop). The isolation between each output eliminates ground-loop
s that could affect the measurement. Since each output is independent and low-power, any risk
of equipment damage is eliminated compared to the use of a single high-power output power supply.
The independence of each loop greatly increases the reliability of the installation.
The outputs allow for all wiring combinations to adapt to specific needs; connecting them in series or
parallel enables the creation of a balanced output, increasing the output current or voltage.
Description:
– The switching version offers high power density
without overheating due to its high efficiency; it also accommodates
a wide range of input voltages (AC or DC).
