Technical FAQs

Can the PW484-50 be used as a standalone 24 V supply?
No, it requires the exclusive Yokogawa base plate connector and cannot function as a general-purpose power source.

How does the PW484 differ from the PW482?
The PW482 is designed for 220–240 V AC mains input, whereas the PW484-50 is tailored for 24 V DC battery or plant power systems.
