Supplementary Units Details

AC Inrush Current Limiter (ICL Series)

The ICL Series allows more power supplies and large capacitive loads on the same circuit breaker, reducing the need for fewer circuit branches and lowering system costs. Available in DIN Rail (ICL-R) or terminal block (ICL-L) types, with 16A or 28A continuous current ratings and corresponding inrush current limiting capabilities.

Redundancy Module (DRDN/ERDN/DR-RDN Series)

These modules secure highest reliability and stability in 1+1 or 1+N redundancy configurations, ensuring continuous operation by providing backup power supply units.

Buffer Module (DBUF Series)

The DBUF Series extends system hold-up time during AC interruptions. It utilizes maintenance-free electrolytic capacitors instead of batteries, saving on maintenance costs and offering a longer functional life span.

DC-UPS Module (DR-UPS Series)

The DR-UPS Series provides an uninterruptible power supply with battery backup, offering long buffer times when AC or DC power fails. It ensures uninterrupted system operation by using external batteries.
