June 28, 2012 — SL Power Electronics introduces CENB1121 & CENB1130 external switch-mode power supplies that deliver 120 and 130 watts respectively of total power at 12V to 24V. Accepting universal input of 100 to 240VAC via a standard IEC320 input connector, CENB models meet the latest energy efficiency and safety standards – including EISA2007, CEC Efficiency Level V – and are ideal for external applications requiring flexible implementation worldwide.
The desktop style power supplies have been designed to power a wide range of industrial/ITE applications including ruggedized computers, environmental monitoring, process control instrumentation, test and measurement, IT, networking, VoIP, and imaging systems.
Featuring high-efficiency operation, the new devices offer regulated output power with low ripple, no load power consumption >0.5W, short circuit and thermal protection. They include Class B EMI filtering and a convenient IEC AC 320 C14 grounded input connector that can accept input line cords with any appropriate plug configuration.
Measuring 8.22 x 2.51 x 1.81 inches ( 209 x 64.4 x 46 mm) and housed in an impact resistant polycarbonate enclosure, both models demonstrate a mean time between failures (MTBF) greater than 100,000 hours.
With an operating temperature range of 0°C to 40°C (with no derating), the CENB1121/1130 can operate in harsh environmental conditions. In addition, the units comply with worldwide safety and performance standards from UL, cUL, CE and RoHS. Modified or custom designs are available as well as custom labeling.
