Add-on Modules for SITOP Power Supply Units

Caution
Product Description
Add-on modules for increasing system availability
A power supply unit on its own cannot guarantee fault-free 24 V supply. Power failures, extreme line voltage fluctuations, or a faulty load can disrupt plant operation and result in high costs. The add-on modules offer everything from extensive protection against interference on the primary and secondary side right up to complete all-round protection.
