Features:

  • Specifically designed for FCU, FIO Node Units, and Optical ESB Bus Repeater Units; not interchangeable with generic power supplies; exclusive connector.
  • Two identical modules can be installed in slots P1 and P2 for power redundancy; ensures continuous operation if one module fails.
  • Compatible with AFV30/50/70 FCUs, ANB10/11 node units, ANT10U repeater, and A2BE1D/A2BE2D base plates; 220‑240V AC input, 230 VA max.
The PW482-10 is not a general‑purpose power supply; it is specifically designed for Yokogawa CENTUM VP Field Control Units (FCU), FIO Node Units, and Optical ESB Bus Repeater Units. Unlike standard industrial power supplies that provide a regulated DC voltage (e.g., 24V DC), the PW482 provides specialized power distribution tailored to the backplane requirements of these units. It connects via an exclusive connector that mates directly with the chassis backplane. The output voltage and current are not published because the module is not intended for standalone use.

The PW482-10 is designed for high‑availability applications where power supply failure cannot be allowed to shut down the control system. Two identical PW482 modules can be installed in slots P1 and P2 of the chassis. Under normal operation, both modules are powered and share the load (or one is active and the other standby). If one module fails – due to input power loss, internal component failure, or overtemperature – the other module continues to supply full power to the backplane. This failover is automatic and requires no operator intervention. For a single (non‑redundant) configuration, only one module is installed, and it must be placed in slot P1.

The PW482-10 is compatible with a broad range of Yokogawa CENTUM VP hardware. It works with AFV30D, AFV30S, AFV50D, AFV50S, AFV70D, and AFV70S Field Control Units. It also powers FIO Node Units (ANB10D, ANB10S, ANB11D, ANB11S) and the Optical ESB Bus Repeater Unit (ANT10U). Additionally, it can be installed on base plates A2BE1D and A2BE2D. This wide compatibility means that a single power supply model can be used across multiple chassis types, simplifying spare parts inventory.

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

Description
The PW482-10 is a power supply module for Yokogawa CENTUM VP systems. It accepts 220‑240V AC ±10% at 50/60 Hz ±3 Hz. The module is designed for installation in Field Control Units (FCU), FIO Node Units, and Optical ESB Bus Repeater Units. Maximum power consumption is 230 VA. Weight is approximately 1 kg. 

When using the PW482-10, engineers must install it in slots P1‑P2. For single configuration, install one module in slot P1. For dual‑redundant configuration, install two identical modules (same model code). The PW482-10 is compatible with FCU models AFV30D, AFV30S, AFV50D, AFV50S, AFV70D, AFV70S.

The PW482-10 has suffix codes. The “-10” indicates standard type with no explosion protection (5) and basic type (0). The basic type has no ISA Standard G3 option and no temperature extension (-20 to 70°C). For harsh environments, select suffix “1” for G3 and temperature option. 

For legacy Yokogawa system expansions, the PW482-10 is a critical spare part for powering FCUs and node units. It is not interchangeable with PW481 (100‑120V AC) or PW484 (24V DC).

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which FCU models work with PW482-10?
The PW482-10 is compatible with AFV30D/S, AFV50D/S, and AFV70D/S Field Control Units. It also works with FIO Node Units (ANB10D/S, ANB11D/S), Optical ESB Bus Repeater Unit ANT10U, and base plates A2BE1D/A2BE2D. Always verify your unit’s specifications.
Can PW482-10 be used in a redundant configuration?
Yes. Install two identical PW482-10 modules in slots P1 and P2. This provides dual‑redundant power. If one module fails, the other continues to supply power, ensuring uninterrupted operation of the FCU or node unit.
Is PW482-10 suitable for hazardous or corrosive environments?
The “-10” suffix has standard type with no explosion protection (5) and basic type (0) – no G3 corrosion protection, no temperature extension. For explosion protection, order suffix “-E” (e.g., PW482-E0). For G3 and temperature (-20 to 70°C), order suffix with “1” (e.g., PW482-51).
Where do I install PW482-10 in the chassis?
Install the PW482-10 in slots P1‑P2. For a single (non‑redundant) configuration, install one module in slot P1. For dual‑redundant configuration, install two identical modules in slots P1 and P2. The module will not function in other slots.
