Higher density in small form factor

Cincon’s CBM101S series of high efficiency, high density full brick, fanless AC/DC power modules is now available from Relec Electronics. The single output modules have a profile height of 17mm. The design offers continuous short-circuit, over-voltage and over-temperature protection. They suit space-constrained industrial applications, including automation equipment, test and measurement instrumentation, telecom and network devices.


The supplies have a universal input range from 90 to 264VAC with outputs of 12, 24, 28, 36 or 48V. The supplies are capable of 100W (120W for five seconds). In-rush current is below 8.5A, with a low leakage current of 0.25mA and no-load input power consumption is <0.5W. Efficiency is up to 94.5 per cent.


Despite its size, the CBM101S integrates EMI filters, bulk capacitors and output capacitors, meaning that no external components are required to pass EMI class. This contributes to the small form factor and reduces the bill-of-materials.


Ambient temperature range is -40 to 85°C and the modules have an operating altitude of 5,000m.
