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 “UltraCaps”) with a capacitance > 3F are connected to the output, the unit might charge the capacitor 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 the built-in large sized output capacitor.
1) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2-5s. After this, the output is switched off for approx. 7s before a new start attempt with duration of 1s is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared, the device will operate normally.

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 the capacitor’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
MTBF stands for M ean T ime B etween F ailure, 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.
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 that statistically 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.
For these types of units the MTTF ( M ean T ime T o F ailure) value is the same value as the MTBF value.

ODULE
The YR40.242 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems.
The device is equipped with two 20A nominal input channels, which are individually decoupled by utilizing MOSFET technology. The output can be loaded with a nominal 40A continuous current.
Using MOSFETSs instead of diodes reduces heat generation, losses and voltage drop between input and output. Due to these advantages, the unit is very narrow and only requires 36mm width on the
DIN-rail.
The device does not require an additional auxiliary voltage and is self-powered even in case of a short circuit across the output. It requires suitable power supplies on the input, where the sum of the continuous short circuit current stays below 26A. This is typically achieved when the power supplies are featured with an intermittent overload behavior (Hiccup Mode).

UF20.241
B
UFFER MODULE
The UF20.241 buffer module is a supplementary device for DC 24V power supplies. It delivers power to bridge typical mains failures or extends the hold-up time after the AC power is turned off.
When the power supply provides a sufficient voltage, the buffer module stores energy in the integrated electrolytic capacitors. When the mains voltage is lost, the stored energy is released to the DC-bus in a regulated process.
The buffer module can be added in parallel to the load circuit at any given point and does not require any control wiring.
One buffer module can deliver 20A additional current and can be added in parallel to increase the output ampacity or the hold-up time.
For longer hold-up times the UF40.241 might also be an option.

EDUNDANCY
The device can be used to built 1+1 redundant systems.
1+1 Redundancy:
Devices can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case one device fails. The simplest way is to put two devices in parallel.
This is called a 1+1 redundancy. In case one device fails, the other one is automatically able to support the load current without any interruption. It is essential to use a redundancy module to decouple devices from each other. This prevents that the defective unit becomes a load for the other device and the output voltage cannot be maintained any more.
1+1 redundancy allows ambient temperatures up to +70°C.
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple devices.
Recommendations for building redundant power systems:
- Use separate input fuses for each device.
- Use separate mains systems for each device whenever it is possible.
- Monitor the individual devices. Therefore, use the DC-OK signal of the device.
- It is desirable to set the output voltages of all devices to the same value (± 100mV) or leave it at the factory setting.

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% .
Ensure that the wire, which is connected to the N-terminal, is appropriately fused.
The maximum allowed voltage between a Phase and the PE must be below 300Vac.

NCLOSURE
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.
