PRODUCT DESCRIPTIONSHORT-FORM DATAThe QS5.DNET power supply is a derivate of the Dimension
QS5 family, which is specially designed to meet theDeviceNet® requirement. The QS5.DNET exists beside the
QS10.DNET, which is the right choice to supply networks
with the thick cables.
The specialties of DeviceNet® power supplies are:
 The nominal and overload currents are sized for the
ratings of the DeviceNet® cables.
 Large load capacitors can be charged in a very shortperiod of time.
 After turn on, the output voltage increases according to
the DeviceNet® timing specification.
 The upper level of the output level is limited to protect
the network.
The most outstanding features are a high efficiency,
compact size, wide-range input voltage, a very low inrush
surge and a DC-OK contact. High immunity to transientsand power surges and a low electromagnetic emission
makes usage in nearly every environment possible.
Unique quick-connect spring-clamp terminals allow a safeand fast installation. A large international approval
package makes this unit suitable for nearly every situation.

**) The extra current to charge network capacitors is available as soon as power comes on and immediately after the end of an output shortcircuit or output overload.

Peak current capability (up to several milliseconds)
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 bedischarged and causes a voltage dip on the output. Detailed curves can be found in chapter 24.1.

The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to thecapacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of adevice. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means thatstatistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit
has been running for 50 000h or only for 100h.

23. APPLICATION NOTES
23.1. 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 thepower supply can deliver extra current. Discharging this capacitor causes a voltage dip on the output. The following
two examples show typical voltage dips:
Fig. 24-1 Peak load with 2x the nominal
current for 50ms, typ.

Fig. 24-2 Peak load with 4x the nominal
current for 5ms, typ.

Peak load 7.6A (resistive) for 50ms
Output voltage dips from 24V to 20V.

Peak load 15A (resistive) for 5ms
Output voltage dips from 24V to 16V.

Please note: The DC-OK relay triggers when the voltage dips more than 10% for longer than 1ms.

23.2. 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 28Vdc. The absorbing energy can be calculated according to the built-in
large sized output capacitor which is specified in chapter 6.

QS5.DNET
24V, 3.8A, NEC CLASS 2, DEVICENET® POWER SUPPLYQ-Series23.3. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 30A (UL) and 32A (IEC). An external protection is only
required if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In
some countries local regulations might apply.
If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of
the circuit breaker. A minimum value of 6A B- or 3A C-Characteristic breaker should be used

23.4. CHARGING OF BATTERIESThe power supply can not be used to charge any kind of batteries since the output voltage adjustment range is too
small.

23.5. OUTPUT CIRCUIT BREAKERS
Standard miniature circuit breakers (MCB’s or UL1077 circuit breakers) are commonly used for AC-supply systems andmay also be used on 24V branches.
MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to
the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.
To avoid voltage dips and under-voltage situations in adjacent 24V branches which are supplied by the same source, afast (magnetic) tripping of the MCB is desired. A quick shutdown within 10ms is necessary corresponding roughly tothe ride-through time of PLC's. This requires power supplies with high current reserves and large output capacitors.
Furthermore, the impedance of the faulty branch must be sufficiently small in order for the current to actually flow.
The best current reserve in the power supply does not help if Ohm’s law does not permit current flow. The following
table has typical test results showing which B- and C-Characteristic MCBs magnetically trip depending on the wire crosssection and wire length.

24V, 3.8A, NEC CLASS 2, DEVICENET® POWER SUPPLYQ-Series23.6. PARALLEL USE TO INCREASE OUTPUT POWER
Do not use power supplies in parallel since the DeviceNet® cable is rated only up to 4A and could be overheated.

23.7. PARALLEL USE FOR REDUNDANCYDo not use power supplies in a standard 1+1 redundancy configuration since the DeviceNet® cable is rated only up to
4A. In a failure mode (short-circuit on the load) a multiple of this current could flow into the DeviceNet® cable.

23.8. SERIES OPERATION
Use the standard QS5.241 power supply when units need to be connected in series for higher load voltages.

23.9. INDUCTIVE AND CAPACITIVE LOADSThe unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.

23.10. OPERATION ON TWO PHASESPower Supply

240V +10% max.

The power supply can also be used on two-phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying
voltage is below 240V+10%. Use a fuse or a circuit breaker to protect the
N input. The N input is internally not protected and is in this caseconnected to a hot wire. Appropriate fuses or circuit breakers are specified
in chapter 24.3 “External Input Protection”.

23.11. 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. In such situations, the inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The power supply is placed in the middle of the box, no other heat producing items are inside the box

24V, 3.8A, NEC CLASS 2, DEVICENET® POWER SUPPLYQ-Series23.12. MOUNTING ORIENTATIONSMounting orientations other than input terminals on the bottom and output on the top require a reduction incontinuous output power or a limitation in the maximum 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
Curve A2

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