Applications
-
Supplying stable isolated 24 V DC power to controller modules (PLCs, Advant Master systems) in automation and process control.
-
Powering field I/O modules, sensors, actuators that require clean, stable DC supply, isolated from AC mains noise.
-
Use in distributed control systems (DCS) in industries such as oil & gas, chemical, water treatment, food & beverage.
-
Infrastructure systems like traffic control, building automation, power substations for control equipment.
-
Environments where power quality is poor or interference/ground loops could affect sensitive control electronics.
Advantages
-
High Stability and Isolation: The isolation(s) protects downstream electronics from noise, transients, ground loop effects.
-
Wide Input Voltage and Flexibility: Able to accept a broad AC input range (and variants possibly DC) so suitable for global installations with varying mains supply.
-
High Output Current: 35 A is relatively large for control power supplies, enabling fewer modules to supply multiple loads.
-
Robust Protection Features: Overload, overvoltage, short‑circuit, thermal protections increase reliability, reduce risk.
-
Durability in Harsh Environments: Good temperature range, conformal coatings (in some variants), built for industrial conditions.
-
Compact Design (for its class): Smaller footprint for the power delivered simplifies cabinet wiring and layout.
