Product introduction

Our range of power supplies covers AC/DC, DC/AC,DC/DC with a wide span of voltages and power, from a few watts to many kilowatts. The extensive standard range, comprising a combination of our own designs and products from our leading partners, is complemented by our custom design capabilities, ensuring we can always provide optimized solutions. Industrial to us is where EN/UL-60950 is the main standard, as for example in automation, building control, signaling, test & measurement and many more. We accommodate any mechanical format and several different cooling principles. Communications interfaces and control software can also be incorporated.

Note

1.At maximum output power, nominal input voltage,  Ta = 25C.

2.Refer to Output Derating Curve (next page) for details of output derating versus input voltage,ambient temperature and mounting method .

3.Refer to picture A for measure results about line regulation,load regulation and ripple & noise

  Ripple & noise are measured at 20MHz by using a twisted pair of load wires terminated with a 0.1uF and 47uF capacitor.
