POWER SUPPLY AC 380-480V Wide-range Input Input Fuses Already Included Requires only Two Legs of a 3-Phase System Width only 40mm Efficiency up to 85.8% Input -Transient Blanking Circuit Included Minimal Inrush Current Surge Full Power Between -25°C and +60°C 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA The Dimension C-Series are cost optimized power supplies without compromising quality, reliability and performance. The C-Series is part of the DIMENSION power supply family. The most outstanding features of CT5.121 are the high efficiency, electronic inrush current limitation, active input transient filter and wide operational temperature range, the small size and other technological design concepts. Output voltage Adjustment range Output current Output power Output ripple Input voltage Mains frequency AC Input current Power factor AC Inrush current Efficiency Losses Temperature range Derating Hold-up time Dimensions The C-Series includes all the essential basic functions. The CT5.121 utilizes only 2 legs of a 3-phase system which saves wiring and installation costs. Furthermore, this allows a smaller unit without compromising the size of the terminals. Due to the low power consumption, an unbalancing of the individual phases is not expected.

The information presented in this document is believed to be accurate and reliable and may change without notice. PE is the abbreviation for Protective Earth and has the same meaning as the symbol Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”. To be defined, value or description will follow later. A figure displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±15%) included. E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V) A figure with the unit (Vac)...
