Power supply 1-phase, 48 V dc Dimension C Series

  • Output current of 10 A
  • Up to 94% efficiency
  • Active PFC
  • High short-circuit currents
  • Hiccup Plus

Product description

Puls Dimension C-series stands for cost optimization without compromising quality, reliability or performance. CPS20.481 high efficiency over a wide load range, which results in reduced power consumption and longer life regardless of load current. An average efficiency is 92.8% with a peak value of 93.9%. In addition, power losses very low at idle, only 2.4 W at 230 V ac.

Short-circuit currents.
CPS20 can leave short-circuit currents which is 4 times the nominal current for 15 ms, which helps secondary fuses and achieve selectivity.


With new pulse short circuit protection you get optimum protection. The unit leaves a very high short circuit that solves fuses and provides sufficient starting current for example dc motors. If the output voltage drops below 25 V DC will be left 2x rated current for 2 seconds, then close the unit by the end to make a new restart attempts after about 18 seconds. This feature ensures a high short-circuit/overload current while avoiding a constant high current that can lead to heat and component damage.

Technical advantages. CPS20 has active power factor correction (PFC) and active power inrush protection that effectively reduces start currents which are ideal if several units are connected in the same phase or if the supply is current limited through example. AC UPS. The protection is always active, regardless of the temperature. DC-OK output, wide temperature range, a large number of approvals and transient filter which ensures operation in störrik electrical environment makes the unit suitable for virtually all installations.


For approved cooling, we recommend free space of 40 mm above. 20 mm under and 5 mm on the sides. (15 mm if there is another power supply)
