Product Introduction – SPW482‑53
The SPW482‑53 is a dual‑output power supply module intended for industrial control / field control / node units. It accepts AC input (nominal 220‑240 VAC) and provides two DC outputs (one low voltage for internal control logic, another higher voltage for field devices). It is designed to work under harsh ambient conditions (temperature, vibration, etc.), with good efficiency, isolation, and compact dimension so it can be installed in dense control cabinets or distributed control systems (DCS). It belongs to Yokogawa’s family of power supply modules used with field control units, node units, safety control units, etc.

Applications
-
Supplying stable power to field control units and node units in distributed control systems.
-
Powering internal control logic (low voltage) and field devices (higher voltage) simultaneously.
-
Retrofit or expansion of DCS cabinets where dual‑output power supply reduces wiring complexity.
-
Industrial plants (petrochemical, power generation, water treatment, etc.) requiring robust modules tolerating wide temperature ranges.
-
Environments requiring redundancy or spare capacity (using multiple SPW482 modules to share load or provide backup).
Advantages
-
Dual output capability (both low‑voltage logic output and higher field output) reduces number of separate power supplies.
-
High efficiency (~92%) lowers heat generation, energy waste, and improves reliability.
-
Wide operating temperature (‑20‑70 °C) enabling usage in harsher climates.
-
Compact form (22.5 mm width) saves space in racks / cabinets with many modules.
-
Reasonable weight (≈0.34 kg) simplifies handling and mounting.
-
Safety features (overvoltage, overcurrent protection, good isolation) enhance durability and protect downstream devices.
-
ISA G3 standard compliance in corrosion resistance for industrial harsh environments.

FAQ (10 Questions & Answers)
Q1: What are the dual outputs of SPW482‑53 used for?
A1: One output (5.1 V DC) is intended for internal control logic or modules in the node/control unit, while the other (24 V DC) supplies field devices or I/O modules needing higher voltage.
Q2: What AC input voltage does the module accept?
A2: It accepts 220‑240 VAC ±10%, at either 50 or 60 Hz.
Q3: What is the maximum power input or consumption?
A3: The module is rated for up to about 230 VA input under full load; idle or partial load consumes less.
Q4: What is its efficient performance?
A4: Efficiency is about 92%, helping reduce waste heat and improve reliability.
Q5: What are its physical size and weight?
A5: It measures roughly 22.5 mm × 99 mm × 114 mm, and weighs about 0.34 kg.
Q6: Over what temperature range does it reliably operate?
A6: From about ‑20 °C up to +70 °C.
Q7: What safety or protection features are built in?
A7: It includes overvoltage protection, overcurrent protection, and good voltage isolation between input and outputs.
Q8: Is it compatible with Yokogawa’s DCS / field control / node units?
A8: Yes; it is designed to integrate with such systems, being part of SPW series power supply modules used in node/control units.
Q9: What kind of mounting or connector interface does it use?
A9: Typically it plugs into a backplane or uses exclusive connectors compatible with Yokogawa’s node or field control unit architecture.
Q10: How does it behave under partial load or in redundancy setups?
A10: Under partial load its outputs remain stable; in systems requiring redundancy you can use dual SPW482‑53 modules or combinations so that one acts as backup to handle load in case of failure.
