M - SERIESLINEAR POWER SUPPLIES WITH HIGH EFFICIENCY AND HIGH RELIABILITYThe M-series has proved to be one of the most reliable series of modular power supplies. Many thousands are beingused without any problems for more than 25 years. According to our statistics over many years the average number ofrepairs is less than one per thousand per year, including faults caused by wrong use. The circuits of these linears arevery simple compared with the complexity of switchers. The number of components is only a fraction of that of aswitcher. Moreover the components are very reliable.The disadvantages compared with switchers are the relatively larger weight and dimensions and a lower efficiency.The M-series modular power supplies are designed for use at a fixed output voltage. The M 15-16 HE for 15 V 16 A has atap point on the transformer secondary so that it can also be used at 12 V 16 A. In the same way the M 60-5 HE can alsobe used at 48 V 5 A.Model Vout Iout Efficiency SizeM 15 - 16 HE 12 V / 15 V 16 A 70 % half rackM 24 - 12 HE 24 V 12 A 74 % half rackM 60 - 5 HE 48 V / 60 V 5 A 75 % half rackM 24 - 20 HE 24 V 20 A 74 % full rackM 48 - 10 HE 48 V 10 A 75 % full rackSome features are:* Extra output terminal via a built-in diode for use in redundant operation* Built-in adjustable overvoltage protection (crowbar type)* Very low output ripple* Fast response to load transients* No generation of RFI* It withstands the high energy impulse test 2.3 Û N 1.3 ms of VDE 0160* Split bobbin transformerhalf rack full rackP.O.
