Bicker Elektronik Donauwörth proudly presents the new PC power supplies BEA-540H and BEA-550H. For the first time, these devices combine high energy efficiency with the robustness of an industry power supply. They meet the requirements of the 80 PLUS©* standard and therefore achieve more than 80% efficiency at 20 %, 50 % and 100 % load. At 400 and 500 watts output rating resp., the BEA-540H is characterized by 85% and the BEA-550H by 86% efficiency. Thanks to a low standby consumption of <1,7 watts both power supplies can also be used in devices according to Energy Star 4.0. They have been designed for continuous 24/7 operation. Increased noise immunity and high-quality components ensure a long availability of the computer. A new feature with the BEA-540H and BEA-550H is a safety clip securing the mains plug from being pulled out inadvertently. More technical data: Input voltage range: 90 to 264 VAC / 47 to 63 Hz Current drain BEA-540H: 6 A at 115 VAC; 3 A at 230 VAC Current drain BEA-550H: 8 A at 115 VAC; 4 A at 230 VAC Inrush current: 20 A at 115 VAC; 40 A at 220 VAC Safety/EMC: TÜV, UL, CE, EN61000-6-2, EN61000-6-4, IEC60950-1 Operating temperature: 0 to +70°C The power supplies come with a short-circuit protection at all outputs as well as an overload protection. Bicker Elektronik guarantees 130.000 hours of MTBF at +50°C. *80 PLUS© is an independent organization for testing the efficiency of power supplies. Any device achieving more than 80% efficiency at 20%, 50% and 100% load resp., is provided with the 80Plus seal of approval. But an 80Plus power supply is only useful if 20% load correspond to the minimum power consumption of the system at IDLE operation! It is therefore pointless using an 80Plus 650watt power supply for an office PC (e.g. Intel C2D E4300, 7600 GT, hard disk, drive) since the power supply will only reach this high efficiency at approx. 120watts. Below 20%, the efficiency is rapidly decreasing. The company Bicker Elektronik GmbH, which was founded in 1994, designs, manu-factures, and distributes solutions for power supply applications. With its product portfolio the company focuses on power systems for industrial automation as well as for industrial or professional environments and medical applications. Thus, the product range not only includes power supply units as such but also DC/DC converters as well as uninterruptible power supplies with DC or AC supply. The main power range of all these power products currently lies between 3 W and 3.000 W.
