Foreword
Further notes on installation requirements
• This device contains no serviceable parts. In the event of damage or malfunction during installation or operation, switch off the device immediately and return it to the factory for inspection. Triggering of an internal fuse indicates an internal defect.
• Install the device in a housing that provides protection against electrical, mechanical and fire
hazards.
• Install the device on a DIN rail according to EN 60715, with the input terminals at the bottom of
the device. Other mounting positions require a reduction of the output current.
• Make sure that the wiring is correct. Make sure that all individual wires of a strand enter the terminal connection.
• Unused screw terminals should be tightened firmly.
• The device is designed for areas with contamination level 2 in controlled environments. No condensation or frost is allowed.
• The device housing offers IP20 protection.
• The device insulation is designed to withstand surge voltages of overvoltage category III according to IEC 60664-1. For delta protective conductor systems, the overvoltage category is reduced
to level II.
• The device is designed to meet the requirements of protection class I according to IEC 61140.
• Do not use the device without a proper PE connection (protective earth).
• The device is suitable for supply from TN, TT and IT networks. The voltage between the L or N
terminal and the PE terminal must not exceed 500Vac continuously.
• An isolating device must be provided for the device input.
• This device is designed for convection cooling and does not require an external fan. Do not obstruct the air circulation.
• The device is designed for altitudes up to 6000m (19685ft). Above 2000m (6560ft) a reduction of
the output current and overvoltage category is required.
• Maintain the following installation distances: 40mm at the top, 20mm at the bottom and 5mm
on the left and right are recommended if the device continuously runs at more than 50% of the
rated output. Increase this distance to 15mm if the adjacent device is a heat source (e.g. another power supply unit). If the device continuously runs at less than 50%, the 5mm distance
can be reduced to zero.
• The device is designed, tested and approved for branch-circuit currents up to 32A (IEC) and
30A (UL) without additional protection. If an external fuse is used, do not use circuit breakers
smaller than 6A (B or C characteristic) to avoid unwanted tripping of the circuit breaker.
• The maximum ambient air temperature is +70°C (+158°F). The operating temperature corresponds to the ambient or ambient air temperature, per definition at 2 cm below the device.
• The device is designed for operation in the relative humidity range between 5% and 95%.

3.7 Lifetime expectancy
The lifetime expectancy shown in the table indicates the minimum number of operating hours (service life)
and is determined by the lifetime expectancy of the built-in electrolytic capacitors. The lifetime expectancy is
stated in operating hours and is calculated according to the specifications of the capacitor manufacturer. The
manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years (131,400h). Any
number exceeding this value represents a calculated theoretical lifetime which can be used to compare
devices.

3.8 MTBF
MTBF stands for Mean Time Between Failure, which is calculated from the statistical failure rate of the
components and indicates the reliability of a device. It is a statistical representation of the probability of
equipment failure and does not necessarily represent the service life of a product.
The MTBF number is a statistical representation of the probability of equipment failure. An MTBF number of
1,000,000h, for example, means that statistically, if there are 10,000 devices in use, one device will fail every
100 hours. However, it is not possible to say whether the failed device has been in operation for 50,000
hours or only 100 hours.
For these device types the MTTF value (Mean Time To Failure) is identical to the MTBF value.

3.16 Dielectric strength
The output voltage is earth-free and has no ohmic connection to earth.
The output is isolated from the input by double or reinforced insulation.
Type and component tests are carried out by the manufacturer. Field tests can be performed in the field
using suitable test equipment that ramps up the voltage with a slow ramp (2s rising and 2s falling). Connect
all input terminals and all output poles to each other before performing the tests. During the test, set the cutoff current to the value shown in the table below.
We recommend connecting either the positive pole, the negative pole or another part of the output circuit to
the protective conductor system. This avoids situations in which the load starts unexpectedly or cannot be
disconnected if an unnoticed earth leakage occurs.

Application notes
4 Application notes
4.1 Peak current capability
The device can deliver peak currents (for up to several milliseconds) that are higher than the specified shortterm currents.
This helps when starting loads with high current intensity. Magnetic coils, contactors and pneumatic modules
often have a stationary coil and a pick-up coil. The inrush current requirement of the pick-up coil is several
times higher than the stationary current and usually exceeds the rated output current (including extra power).
The situation is exactly the same when starting a capacitive load.
The peak current capability also ensures safe operation of downstream circuit breakers of load circuits. The
load circuits are often individually fused with circuit breakers or fuses. In the event of a short circuit or
overload in a circuit, the fuse or circuit breaker needs a certain amount of overcurrent to open in time. This
prevents a voltage drop in adjacent circuits.
The additional current (peak current) is supplied by the power converter and the built-in large-size output
capacitors of the power supply unit. The capacitors are discharged during such an event, which leads to a
voltage drop at the output. The following two examples show typical voltage drops for ohmic loads:
Fig.14: 20A peak current for 50ms, typ. (2x nominal current)
Fig.15: 50A peak current for 5ms, typ. (5x nominal current)
PS2031-2410-0000 29Version: 1.0
Application notes
Peak current voltage drops
Typically from 24V to 6V At 20A for 50ms, ohmic load
Typically from 24V to 12V At 50A for 2ms, ohmic load
Typically from 24V to 3V At 50A for 5ms, ohmic load
4.2 Output circuit breakers
Standard circuit breakers (or UL1077 circuit breakers) are generally used for AC supply systems and can
also be used for 24V branches.
Circuit breakers are used to protect wires and circuits. If the ampere value and the characteristics of the
circuit breaker are matched to the wire thickness used, the wiring is considered thermally safe, regardless of
whether the circuit breaker opens or not.
To avoid voltage drops and situations with undervoltage in adjacent 24V branches fed from the same source,
a fast (magnetic) trip of the circuit breaker is desirable. Fast switch-off within 10ms is required, which
approximately corresponds to the bridging time of PLC. This requires power supplies with high reserve
current and large output capacitors. In addition, the impedance of the faulty branch must be sufficiently small
for the current to actually flow. The strongest power supply is of no use if the ohmic law does not allow
current to flow. The following table contains typical test results that show which circuit breakers with B and C
characteristics trip magnetically, depending on the wire cross-section and the wire length.

Application notes
4.3 Charging batteries
The power supply can be used to charge lead-acid batteries or maintenance-free batteries (SLA or VRLA
batteries). Two 12V batteries connected in series are required.
Instructions for charging batteries:
• Make sure that the ambient temperature of the power supply remains below 45°C.
• Adjust the output voltage, measured at no load and at the battery end of the cable, very precisely to the
end-of-charge voltage.
End-of-charge voltage 27.8V 27.5V 27.15V 26.8V
Battery temperature 10°C 20°C 30°C 40°C
• Use a 16A protective circuit breaker or a decoupling diode between the power supply and the battery.
• Make sure that the output current of the power supply is below the permissible charging current of the
battery.
• Only use matched batteries when connecting 12V types in series.
• The reverse current to the power supply is typically 8mA. This reverse current can discharge the
battery when the power supply is switched off, unless a decoupling diode is used.
4.4 Series connection
Power supplies of the same type can be connected in series to increase the output voltages. As many
devices can be connected in series as necessary, as long as the sum of the output voltages does not exceed
150Vdc. Voltages with a potential higher than 60Vdc are no longer regarded as safety extra-low voltage and
can be dangerous. Such voltages must be protected with a touch guard.
Avoid application of return voltage (e.g. from a braking motor or battery) to the output terminals.
Restrictions: Keep a mounting distance of 15mm (left/right) between two power supplies and do not install
the power supplies above each other. Power supplies connected in series should only be used in the
standard installation position (terminals on the underside of the device).
Remember that leakage current, electromagnetic interference, inrush current and harmonics increase when
using multiple power supplies.
Fig.17: Series connection
4.5 Parallel use to increase power
PS2031-2410-0000 power supplies can be connected in parallel to increase the output power. The output
voltage of all power supplies must be set to the same value (±100mV) in "Single Use" mode and with the
same load conditions on all devices, or the factory settings of the devices can be retained. After making
adjustments, set the unit to "Parallel Use" mode to achieve load sharing. "Parallel Use" mode regulates the
output voltage so that the voltage at no load is approx. 4% higher than at nominal load. See also Output
chapter [}15]
PS2031-2410-0000 31Version: 1.0
Application notes
The ambient temperature may not exceed +60°C.
If more than three devices are connected in parallel, a fuse or circuit breaker with a rated current of 15A or
16A is required at each output. Alternatively a diode can be used.
Restrictions: Keep a mounting distance of 15mm (left/right) between two power supplies and do not install
the power supplies above each other. In parallel mode power supplies should only be used in the standard
installation position (terminals on the underside of the device), not in other installation positions or under
other conditions that require a reduction in the output current (e.g. installation altitude ...).
Remember that leakage current, electromagnetic interference, inrush current and harmonics increase when
using multiple power supplies.
Fig.18: Parallel connection
4.6 Operation on two phases
No external protective device is required to protect against phase failure.
The power supply may only be operated continuously on two strands of a three-phase system if the output
power is reduced according to the curves shown below. Exceedance of these limit values over extended
periods leads to thermal shutdown of the device.
Fig.19: Operation on two phases
Make sure the EMC performance, Hold-up time and losses are different from three-phase operation.
Therefore check the suitability of your individual application.
The use of only two strands of a three-phase system is not covered by the official approval. Therefore,
additional examinations may be required during the approval process of the final system.

current at 24 V
4.7 Use in a tightly sealed enclosure
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure is
higher than outside. In this case, the temperature inside the enclosure is considered the ambient
temperature for the power supply.
In the following test arrangement, the device is placed at the center of the enclosure, and there are no other
heat-generating objects in the enclosure. The load is placed outside the box.
The temperature sensor inside the box is placed at the center of the right side of the power supply at a
distance of 1 cm.
The following measurement results can be used as a reference to estimate the temperature rise within the
enclosure.
