Features:

  • Provides 230 VA power for Yokogawa DCS field control units.
  • Enables high-availability systems with two identical modules.
  • Supports -20°C to 70°C operation with ISA Standard G3 option.
The PW482-10 S2 is engineered to convert 220-240V AC input power into stable DC power for Yokogawa CENTUM VP DCS systems. With maximum power consumption of 230 VA and input frequency tolerance of 50/60 Hz ±3 Hz, the PW482-10 S2 delivers consistent performance even under fluctuating grid conditions. The exclusive connector interface ensures secure and reliable connections. This robust power conversion capability makes the PW482-10 S2 ideal for critical industrial applications where uninterrupted power supply is essential for maintaining process control and system availability.

The PW482-10 S2 supports both single and dual-redundant configurations to meet varying system reliability requirements. In single configuration, the PW482-10 S2 must be installed in slot P1. For critical applications requiring maximum uptime, two identical PW482-10 S2 modules can be installed in slots P1 and P2 for dual-redundant power supply. This architecture ensures that if one module fails, the other continues to provide power, eliminating single points of failure and significantly enhancing system availability for continuous process operations.

The PW482-10 S2 is available with multiple suffix code options to suit diverse installation environments. The -5 suffix provides standard type without explosion protection, while the -E suffix offers explosion protection for hazardous areas. The -1 suffix includes ISA Standard G3 option with extended temperature range from -20°C to 70°C, making the PW482-10 S2 suitable for harsh industrial environments. Installation restrictions require the PW482-10 S2 to be installed in specified slots P1-P2 of compatible units including FCU, FIO Node Units, and Optical ESB Bus Repeater Units.

The PW482-10 S2 YOKOGAWA Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

YOKOGAWA PW482-10 S2 Power Supply Module Specs

General

  • Manufacturer YOKOGAWA
  • Model PW482-10 S2
  • Condition New Original ready stock
  • Product Family SPW482-13,PW482-S01,PW482-11 S2,PW482-50 S2
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Field Control Unit (FCU) Baseboards: Supplies the critical system power required by central processor modules (such as the CP461 or CP471) to execute continuous, sub-millisecond process automation loops.
  • FIO (Field Network I/O) Extension Nodes: Powers local and remote I/O node units (e.g., ANB10D or ANR10D), energizing the backplanes that read analog/digital field transmitters.
  • Bus Communication Components: Drives the master-side EC401 ESB Bus Coupler modules and slave-side SB401-10 interfaces, ensuring the cabinet's internal and inter-rack communication buses remain active without dropping data packets.
  • Voltage and Frequency Tolerances: Operates on a 220–240 V AC nominal input with a robust voltage fluctuation allowance of 198 V to 264 V AC (±10%). It handles frequency drifts of 50/60 Hz ±3 Hz seamlessly.
  • Temperature and Thermal Management: Built to operate reliably across standard ambient control cabinet temperatures ranging from 0°C to +60°C. Its high-efficiency topology minimizes internal thermal dissipation, reducing localized heat buildup inside sealed enclosures.
  • ISA-S71.04 G3 Conformal Coating: The module is available with standard G3-class environmental protection coatings. This protects the internal circuit board from corrosive gases commonly found in industrial plants, such as hydrogen sulfide (H₂S) and sulfur dioxide (SO₂).
  • LED Status Diagnostics: The front face of the module features direct visual indicator LEDs. A solid HRDY (Hardware Ready) Green LED shows healthy input/output states, while a fault or input dropout immediately triggers an indicator change to alert maintenance teams during visual inspections.
  • DCS System Alarm Integration: Internal circuitry continuously monitors output current levels, overvoltage states, and thermal thresholds. Any internal component degradation or input voltage failure drops the internal status signal, triggering an immediate System Alarm on the CENTUM VP Human Interface Station (HIS) Operator Console.
  • Dual-Redundant Load Sharing Control: When paired with a second identical PW482 module on a dual-redundant baseplate (e.g., inside an AFV30D or ANB10D chassis), the two modules operate in a balanced parallel load-sharing configuration.
