C–Series

1. GENERAL DESCRIPTION

The Dimension C-Series are cost optimized power
supplies without compromising quality, reliability
and performance. The C-Series is part of the
Dimension power supply family, existing alongside
the high featured Q-series.

The C series includes all the essential basic functions
and the devices have a power reserve of 20%. This
extra current may even be used continuously at
temperatures up to +45°C. The most important
features are the small size, the high efficiency and
the wide temperature range.

The Auto-select input makes worldwide installation
and usage very simple. Defects or system failures
caused by wrongly set switches can not occur.

Peak current capability (up to several ms)

The power supply can deliver a peak current which is higher than the specified short term current. This helps to start
current demanding loads or to safely operate subsequent circuit breakers.

The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will
be discharged and causes a voltage dip on the output. Detailed curves can be found in chapter 25.1.

The Lifetime expectancy shown in the table indicates the operating hours (service life) and is determined by the
lifetime expectancy of the built-in electrolytic capacitors.

Lifetime expectancy is specified in operational hours. Lifetime expectancy is calculated according to the capacitor’s
manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment.

MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates
reliability of a device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily
represent the life of a product.

End-devices for professional applications with an input power > 1000W do not need to fulfill EN 61000-3-2.

Comments:

- The average input power must be determined in accordance with EN 61000-3-2.

- Industrial mains supplies with their own transformer are considered to be “non-public”.

- Where individual self-contained items of equipment are installed in a rack or case
(e.g. devices connected in parallel), they are regarded as being individually connected to the
mains supply. The rack or case need not be tested as a whole. Alternatively it is also permitted
to assess the whole rack or case. This is recommended for devices used in professional
applications with an input power greater than 1000W.

25. APPLICATION NOTES

25.1. PEAK CURRENT CAPABILITY

Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current
demand of the pick-up coil is several times higher than the steady state current and usually exceeds the nominal
output current (including the PowerBoost) The same situation applies, when starting a capacitive load.

Branch circuits are often protected with circuit breakers or fuses. In case of a short or an overload in the branch
circuit, the fuse needs a certain amount of over-current to trip or to blow. The peak current capability ensures the
safe operation of subsequent circuit breakers.

Assuming the input voltage is turned on before such an event, the built-in large sized output capacitors inside the
power supply can deliver extra current. Discharging this capacitor causes a voltage dip on the output. The following
two examples show typical voltage dips:

25.3. BACK-FEEDING LOADS

Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called
return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).

This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power
supply. It does not matter, whether the power supply is on or off.

The maximum allowed feed back voltage is 35Vdc. The absorbing energy can be calculated according to the built-in
large sized output capacitor which is specified in chapter 8.

25.4. OUTPUT CIRCUIT BREAKERS

Standard miniature circuit breakers (MCBs) can be used for branch protection. Ensure that the MCB is rated for DC
voltage, too. The following tests show which circuit breakers the power supply typically trips.

Circuit breakers have huge tolerances in their tripping behavior. Therefore, these typical tests can only be used as a
recommendation or for comparing two different power supplies. Furthermore, the loop impedance has a major
influence on whether a breaker trips or not. Two tests were performed, representing typical situations:

Test 1: Short circuit with S1 on the power supply end of the cable (loop impedance approx. 20mOhm)

Instructions for use in series:

a) It is possible to connect as many units in series as needed,

providing the sum of the output voltage does not exceed
150Vdc.

b) Voltages with a potential above 60Vdc are not SELV any

more and can be dangerous. Such voltages must be installed

with a protection against touching.
c) For serial operation use power supplies of the same type.
d) Earthing of the output is required when the sum of the

output voltage is above 60Vdc.
e) Keep an installation clearance of 15mm (left/right) between

two power supplies and avoid installing the power supplies

on top of each other.

Avoid return voltage (e.g. from a decelerating motor or

Note:
battery) which is applied to the output terminals.

25.7. PARALLEL USE TO INCREASE OUTPUT POWER

The power supply shall not be used in parallel to increase the output power.

25.8. PARALLEL USE FOR 1+1 REDUNDANCY

Power supplies can be paralleled for 1+1 redundancy to gain a higher system availability. Redundant systems require
a certain amount of extra power to support the load in case one power supply unit fails. The simplest way is to put
two C-Series power supplies in parallel. In case one power supply unit fails, the other one is automatically able to
support the load current without any interruption. This simple way to build a redundant system has two major
disadvantages:

- The faulty power supply can not be recognized. The green LED will still be on since it is reverse-powered from
the other power supply.

- It does not cover failures such as an internal short circuit in the secondary side of the power supply. In such a ­virtually nearly impossible - case, the defective unit becomes a load for the other power supplies and the output
voltage can not be maintained any more.

This can only be avoided by utilizing decoupling diodes which are included in the decoupling module YR2.DIODE or
redundancy module YRM2.DIODE.

Recommendations for building redundant power systems:
a) Use separate input fuses for each power supply.
b) Monitor the individual power supply units. A DC-ok lamp and a DC-ok contact is included in the redundancy

module YRM2.DIODE. This feature reports a faulty unit.

c) When possible, connect each power supply to different phases or circuits.

branch has an ampacity greater than this. In some countries local regulations might apply. Check also local codes and
local requirements.

If an external fuse is necessary or utilized, a minimum value is required to avoid undesired tripping of the fuse.

25.11. USE IN A TIGHTLY SEALED ENCLOSURE

When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher
than outside. The inside temperature defines the ambient temperature for the power supply.

25.12. MOUNTING ORIENTATIONS

Mounting orientations other than input terminals on the bottom and output on the top require a reduction in
continuous output power or a limitation in the max. allowed ambient temperature. The amount of reduction
influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous
operation can be found below:

Curve A1 Recommended output current.
Curve A2 Max allowed output current (results approx. in half the lifetime expectancy of A1).
