For 4–20 mA current loops, SIL 2 / SIL 3
Low-noise linear version or high-density switching version
Total protection
Short circuits, overloads, thermal protection
1 to 8 isolated outputs
Complete circuit independence
Extended-temperature, long-life version:
AL45DLL “long life” with polymer-filled
Applications
4–20 mA loop power supply
with current limiting (transmitter protection)
Hart protocol, very low noise
SIL2 and SIL3 compliance according to IEC 61508 (redundant version)
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 significantly 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)
