Power supply 2-phase, 12 V dc Dimension C Series

  • Output current 8 A
  • Up to 85.8% efficiency
  • Active transient
  • High reliability
  • Integrated primary fuses

Product description

Puls Dimension C-series stands for cost optimization without compromising on quality, reliability or performance.
CT5 has integrated primary fuses, which make it possible to connect the unit without the requirement of intermediate fuses up to 32 A, which saves space and money. The efficiency is high over a wide load range, which reduces power consumption and give a longer life regardless of load current. An average efficiency value is 84.7% with a top value of 85.4%.

The power supply unit can provide a higher short circuit current for a short time, which helps to trip the secondary fuses. Active transient filters ensure operation even in very disruptive electrical environments, in addition, CT5 features active inrush current protection, which means a very low starting current, even if the unit has been in operation for some time. Especially useful for redundant/parallel connected systems.

Power supply unit connected for 2 phases, which saves both wiring and fuse. Thanks to its low power consumption, the affect of unbalance in the 3- phase system becomes negligible.


We recommend clearance of 40 mm and 20 mm below the unit and 5 mm on the sides.
