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 stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statisticalrepresentation 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 failevery 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.

22.ACCESSORY
22.1. UF20.241 BUFFER MODULE
This buffer unit is a supplementary device for DC 24V power supplies. It delivers power to bridge
typical mains failures or extends the hold-up time after turn-off of the AC power. In times when
the power supply provides sufficient voltages, the buffer module stores energy in integrated
electrolytic capacitors. In case of mains voltage fault, this energy is released again in a regulated
process. One buffer module can deliver 20A which can also be used to support peak current
demands.
The buffer unit does not require any control wiring. It can be added in parallel to the load circuit
at any given point. Buffer units can be added inPower

23.APPLICATION NOTES
23.1. 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 35Vdc. The absorbing energy can be calculated according to the built-in large sized output
capacitor which is specified in chapter 6.

23.2. 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 10A B- or 6A C-Characteristic breaker should be used.

23.3. PARALLEL USE TO INCREASE OUTPUT POWER
Do not use the power supply in parallel to increase the output power.

23.4. PARALLEL USE FOR REDUNDANCYPower supplies can be paralleled for redundancy to gain higher system
availability. Redundant systems require a certain amount of extra power tosupport the load in case one power supply unit fails. The simplest way is to put
two power supplies in parallel. This is called a 1+1 redundancy. In case one
power supply unit fails, the other one is automatically able to support the load
current without any interruption.
Please note: This simple way to build a redundant system does not cover failures
such as an internal short circuit in the secondary side of the power supply. Insuch a case, the defect unit becomes a load for the other power supplies and theoutput voltage can not be maintained any more. This can only be avoided byutilizing decoupling diodes which are included in the redundancy module
YR2.DIODE.

a)

The preferred power supply is the PIC120.241C since it has a DC-OK signal contact included, which the PIC120.242C does not have.
Use this DC-OK signal contact to monitor the individual power supply units.

b)

Use separate input fuses for each power supply.

c)

Use separate mains systems for each power supply whenever it is possible.

d)

It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

23.5. SERIES OPERATION

Unit A

Power supplies of the same type can be connected in series for higher output voltages.
It is possible to connect as many units in series as needed, providing the sum of theoutput voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc are not
SELV any more and can be dangerous. Such voltages must be installed with a protection
against touching.

AC

Earthing of the output is required when the sum of the output voltage is above 60Vdc.

(see notes)

Keep an installation clearance of 15mm (left / right) between two power supplies andavoid installing the power supplies on top of each other.
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

23.6. INDUCTIVE AND CAPACITIVE LOADSNo limitations for inductive loads
No limitations for capacitive loads in combination with an additional resistive type of load.
Limitations apply for capacitive loads in combination with constant current type of loads:- max. 10mF with an additional 2.5A constant current load and- max. 5mFwith an additional 5A constant current load.

23.7. CHARGING OF BATTERIES
Do not use the power supply to charge batteries.
