Safety instructions and installation requirements for the PS1111-2403-0002 power supply
DANGER
Danger of electric shock, fire, injuries, injuries resulting in death!
• Do not use the power supply without proper grounding (protective conductor). Use the terminal at the in-
put terminal strip for the earth connection, not one of the screws on the housing.
• Switch off the power supply before working on the device. Provide protection against unintentional re-
connection.
• Ensure proper wiring by following all local and national regulations.
• Do not modify or attempt to repair the device.
• Do not open the device, as high voltages are present inside.
• Avoid foreign bodies entering the housing.
• Do not use the device in damp locations or in areas where moisture or condensation is likely to occur.
• Do not touch the device when it is switched on or immediately after it has been switched off. Hot sur-
faces can cause burns.
Further notes on installation requirements
• This device contains no parts that require maintenance. If an internal fuse trips, this is due to an
internal defect.
• If any damage or malfunction occurs during installation or operation, turn off the power supply
immediately and return the device to the factory for inspection.
• 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.
• The device is designed for areas with a degree of pollution 2 in controlled environments. No con-
densation or frost is allowed.
• The device housing offers IP20 protection. The housing offers no protection against spilled liq-
uids.
• The device insulation is designed to withstand pulse voltages of overvoltage category III accord-
ing to IEC 60664-1.
• The device is designed to meet the requirements of protection class II according to IEC 61140.
• The device is suitable for supply from TN, TT or IT networks. The continuous voltage between
the input terminal and the PE potential must not exceed 300Vac.
• An isolating device must be provided for the device input.
• The device is designed for convection cooling and does not require an external fan. The air flow
must not be obstructed, and the ventilation grille must not be covered!
• The device is designed for altitudes up to 5000m (16400ft). Above 2000m (6560ft) the overvolt-
age category is reduced to level II, and a reduction of the output current is required.
• Observe the following minimum installation distances: 40 mm at the top, 20 mm at the bottom, 0
mm left and right. Increase the distance from 0 to 15 mm if the adjacent device is a heat source.
• The device is designed, tested and approved for junction circuits up to 20A without an additional
protective device. If an external fuse is used, do not use circuit breakers with lower characteristic
than 6A B or 4A C in order to avoid unwanted tripping of the circuit breaker.
• The maximum ambient air temperature is +70°C (+158°F). The operating temperature corre-
sponds 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%.

2.3 Terminology and abbreviations
PE and the earthing
symbol
PE is the abbreviation for "protective earth" and has the same meaning as the
earthing symbol
Earth, ground This document uses the term “earth” which is the same as the U.S. term “ground”.
T.b.d. Still to be defined, value or description will follow in due course.
AC 230V A value preceded by "AC" or "DC" represents a nominal voltage or a nominal
voltage range. The nominal voltage or the nominal voltage range may be provided
with tolerances. (e.g. AC 230V ±10%). The calculated total range then indicates
the working range of the device.
Example:
DC 12V refers to a 12V battery, regardless of whether it is fully charged
(13.7Vdc) or discharged (10Vdc).
230Vac A value followed by the unit Vac or Vdc is an instantaneous value that does not
contain any additional tolerances.
50Hz vs. 60Hz Unless otherwise specified, AC 100V and AC 230V parameters are valid at a
mains frequency of 50Hz. AC 120V parameters are valid for a mains frequency of
60Hz.

3.3 Input inrush current
An NTC limits the input inrush current after the input voltage is switched on. The inrush current surge
depends on the input voltage and the ambient temperature. The output load has no influence on the value of
the inrush current surge.
The charge current of the interference suppression capacitors during the first few microseconds after
switching on is not taken into account.

3.4 Output
The output provides an SELV/PELV nominal voltage that is electrically isolated from the input voltage.
The output is designed to supply any type of load, including capacitive and inductive loads. Capacitive loads
should not exceed 5500µF with 3.8A or 7000µF with 1.9A additional current load.
In the event of severe overload (if the output voltage drops below 14V) the power supply delivers a
continuous output current for 20ms. The output is then switched off for approx. 160ms before a new start
attempt is automatically made. This cycle is repeated as long as the overload exists. The device starts
operating normally again once the overload has been rectified.
Output voltage Nom. 24V
Adjustment range Min. 24-28V Guaranteed value
Max. 29.0V This is the maximum output voltage that can occur in the end position of the po-
tentiometer in clockwise direction due to tolerances. It is not a guaranteed

3.5 Hold-up time
The hold-up time is the time during which the output voltage of a power supply remains within the
specification after a loss of input power. The hold-up time depends on the output load.
At no load the hold-up time can be up to several seconds. During this time, the green DC OK lamp also lights
up.

3.10 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.
Please note: 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 service life which can
be used to compare devices.

640,000h 720,000h 815,000h At 24V, 1.9A and +25°C
3.11 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.
