5. OUTPUT
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.
The output is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors, such as EDLCs(electric double layer capacitors or "Ultracapacitors"with a capacitance > 0.3F are connected to the output, the unit might charge thecapacitor in an intermittent mode.
The output is electronically protected against overload, no-load and short-circuits. In case of a protection event, audible noise may
occur.

The unit 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 absorbing energy can be calculated according to thebuilt-in large sized output capacitor.

1) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 1s. After this, the output is switched off forapprox. 9s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared, thedevice will operate normally. See Fig. 6-3.

12. LIFETIME EXPECTANCYThe 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.

13. MTBF
MTBF stands for Mean Time Between Failures, 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 cannot be determined if the failed unit
has been running for 50 000h or only for 100h.
For these types of units, the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

18. DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground.
The output is insulated to the input by a double or reinforced insulation.
Type and routine tests are conducted by the manufacturer. Field tests may be conducted in the field using the appropriate test
equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output
poles before conducting the test. When testing, set the cut-off current settings to the value in the table below.
We recommend that either the + pole or the – pole shall be connected to the protective earth system. This helps to avoid situations inwhich a load starts unexpectedly or cannot be switched off when unnoticed earth faults occur.

23. APPLICATION NOTES
23.1. PEAK CURRENT CAPABILITY
The unit can deliver peak currents (up to several milliseconds) which are higher than the specified short-term currents.
This helps to start current demanding loads. 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. The same situation applies when starting a capacitive load.
The peak current capability also ensures the safe operation of subsequent circuit breakers of load circuits. The load branches are often
individually protected with circuit breakers or fuses. In case of a short or an overload in one branch circuit, the fuse or circuit breakerneed a certain amount of over-current to open in a timely manner. This avoids voltage loss in adjacent circuits.
The extra current (peak current) is supplied by the power converter and the built-in large sized output capacitors of the power supply.
The capacitors get discharged during such an event, which causes a voltage dip on the output. The following three examples show
typical voltage dips for resistive loads:

(2x the nominal current)

23.2. CHARGING OF BATTERIESThe power supply can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VRLA batteries are needed in seriesconnection.
Instructions for charging batteries:a)

Use only matched batteries when putting 12V types in series.

b)

Ensure that the ambient temperature of the power supply stays below 40°C for mains voltage of AC 120V or higher and 35°C formain voltage of AC 100V.

c)

Use a 10A circuit breaker or a blocking diode between the power supply and the battery.

d)Ensure that the output current of the power supply is below the allowed charging current of the battery.

e)

The return current to the power supply is typically 8mA. This return current can discharge the battery when the power supply isswitched off except in case a blocking diode is utilized.

f)

Set the output voltage, measured at no load and at the battery end of the cable, very precisely to the end-of-charge voltage. The
voltage should be set to 27.8V at 10°C, 27.5V at 20°C, 27.15V at 30°C and 26.8V at 40°C ambient temperature.

23.3. SERIES OPERATION
Do not use the power supply in series. The leakage current will be too high to meet the medical requirements.

23.4. PARALLEL USE TO INCREASE OUTPUT POWER
Do not use the power supply in parallel. The leakage current will be too high to meet the medical requirements.

23.5. PARALLEL USE FOR REDUNDANCYDo not use the power supply in parallel. The leakage current will be too high to meet the medical requirements.

23.6. OPERATION ON TWO PHASESPower Supply

The power supply can also be used on two-phases of a three-phase-system. Such aphase-to-phase connection is allowed as long as the supplying voltage is below
240V+10%.

240V +10% max.

Ensure that the wire, which is connected to the N-terminal, is appropriately fused.

23.7. 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
The temperature sensor inside the box is placed in the middle of the right side of the power supply with a distance of 1cm.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
