PULS
Power supply 1-phase, 12 V dc Dimension C Series
Puls Dimension C-series stands for cost optimization without compromising quality, reliability or performance. CPS20.121 high efficiency over a wide load range, which results in reduced power consumption and longer life regardless of load current. An average efficiency is 91.6% with a peak value of 92.6%. In addition, power losses very low at idle, only 3 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.
Hiccup Plus.
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 falls below 6 V dc is 2x the rated power is left 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 actively current 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 interference prone electrical environment makes the unit suitable for virtually all installations.
For a good cooling, we recommend a clearance of 40 mm over 20 mm below and 5 mm on the sides. (15 mm on the sides of adjacent product is a heat source, such as another power supply.)
