M - SERIES

LINEAR POWER SUPPLIES WITH HIGH EFFICIENCY AND HIGH RELIABILITY

The M-series has proved to be one of the most reliable series of modular power supplies. Many thousands are being

used without any problems for more than 25 years. According to our statistics over many years the average number of

repairs is less than one per thousand per year, including faults caused by wrong use. The circuits of these linears are

very simple compared with the complexity of switchers. The number of components is only a fraction of that of a

switcher. 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 M15-16 HE for 15 V 16 A has a

tap 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 also

be used at 48 V 5 A.

Current limit

The linear M-models

have a fold back overload characteristics (a constant

current characteristic would overheat the series pass

transistors when the output is short circuited).

A ‘delayed fold back’ is used to avoid problems during

switching-on of series connected power supplies or

non linear loads. The cur-

rent limit is adjustable from

about 40 to 100% of the

rated current.

Remote sensing

Remote sensing at the load

point can be used to com-

pensate for the voltage

drop across the load leads.

Max. 2 V per load lead can

be compensated. The voltage across the output will

rise accordingly, which will limit the max. AC input

voltage swing (check graphs on next page). Also the

OVP has to be set higher. The output is protected

against accidental interruption or reversing of the

sense leads.

A capacitor of 1000 uF across the load can be usefull

to lower the impedance caused by long load leads.

Efficiency

The 70 to 75% efficiency of the M series is high for linear

power supplies. The power supplies are dimensioned

to stay within regulation down to 198 V AC input. How-

ever if the line voltage is already stabilized and never

drops below 215 V, the input can be connected to the

240 V tap of the transformer. This will still increase the

efficiency of the M 24-20 HE from 74 to 79%, saving

considerable heat.

Parallel operation

With parallel operation the current will not be shared

equally but the current limit of each unit will avoid over-

loading. The current sharing is better if the load wires

are of equal length and the outputs adjusted at equal

voltages. To do this a multimeter can be used to mea-

sure the difference of the output voltages. Remote

sensing is not recommended with parallel operation.

To enable parallel operation at higher ambient temper-

atures the current limit of all units can be set lower. At

parallel operation without separation diodes, the OVP

has to be turned out of range (high) because it is only

rated for one power supply.

Parallel operation for redundancy

For redundant parallel operation an extra positive out-

put terminal via a built-in diode is available.

Remote sensing cannot be used.

Redundant parallel operation

Output voltage adjustment range

The M-series is meant for use at a fixed output

voltage. However it can be used over a larger

range at a lower output current or with a smaller

AC input variation (see graphs). The adjustment

ranges are given below.

M 24-12 HE 24 - 28 V

M 24-20 HE 24 - 28 V

M 48-10 HE 48 - 54 V

M 15-16 HE

if connected for 12 V: 12 - 14 V

if connected for 15 V: 15 - 17 V

M 60-5HE

if connected for 48 V: 48 - 54 V

if connected for 60 V: 60 - 64 V

The M 15-16 HE has a tap on the transformer sec-

ondary for use at 12 V instead of 15 V. To avoid

overheating of the series pass transistors it is very

important not to forget to connect it to the lower tap

when turning down the output to 12 V. The same

applies for the M 60-5 HE for 60 and 48 V.
