Safety and warning notes

WARNING – Explosion Hazard Do not disconnect Equipment unless power has been switched off or

the area is known to be non-hazardous.

WARNING – Explosion Hazard. Substitution of components may impair suitability for class I, Division 2.

WARNING – Switch off the system before connecting the module. Never work on the machine when it

is live. The device must be installed in according with UL508. The device must have a suitable isolating facility

outside the power supply unit, via which can be switched to idle. Danger of fatal Injury!

Parallel Connection, to Increase Output Power:

•Made parallel connection with same model of power supply to

increase the output power.

•Adjust the output approximately to the same value (± 20mV)

applying 1-2 A load to all devices output before connecting

them in parallel.

•Easy parallel connections Jumper. In FLEX280xxX and

FLEX500xxX for more power, you must change position of the

jumper to enable parallel connection. In this mode you can put

in parallel up to 4 power supply

Parallel connection Redundancy:

Power supplies can be paralleled for 1+1 redundancy to obtain a

higher system availability. Redundant systems require a certain

amount of extra power to support the load in case one power supply

unit fails. The simplest way is to put two FLEX power supplies in

parallel. In case one power supply unit fails, the other one is

automatically able to support the load current without any

interruption. This simple way to build a redundant system has two

major disadvantages:

- The faulty power supply can not be recognized. The LED will still

be ON since it is reverse-powered from the other power supply.

It does not cover failures such as an internal short circuit in the secondary side of the power supply. In such a -

virtually nearly impossible - case, the defective unit becomes a load for the other power supplies and the output

voltage can not be maintained any more.

This can only be avoided by utilizing decoupling diodes which are included in the Redundancy Module MR220.

Recommendations for building redundant power systems:

a) Use separate input fuses for each power supply.

b) Monitor the individual power supply units. A DC-Led and Power Good Contact are already included on FLEX

power supplies. This feature reports a faulty unit; see power Good Section for any technical detail.

c) When possible, connect each power supply to different phases or circuits.

Serial connection:

a) It is possible to connect as many units in series as needed, providing the sum of the output voltage does not

exceed 150Vdc.

b) 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.

c) For serial operation use power supplies of the same

type.

d) Earthing of the output is required when the sum of the

output voltage is above 60Vdc.

e) Keep an installation clearance of 15mm (left/right)

between two power supplies and avoid installing the power

supplies on top of each other. Note: Avoid return voltage

(e.g. from a decelerating motor or battery) which is applied

to the output terminals.

Power Good Output Function

(No for FLEX60xxX)

Output are used for preventive function

monitoring of the power supply. An electrically isolated

signal contact is available. The signal contact Closes

when output power is OK and Opens when output voltage

falls below 20Vdc ±5%. This feature is particularly useful in redundant

applications.

Power Good Contact rating:

Max. DC1: 30 Vdc 1 A;

AC1: 60 Vac 1A Resistive load (EN 60947-4-1)

Min.:1mA at 5 Vdc Min permissive load

Protection:

On the primary side: the device is equipped whit an internal fuse; follow the next page table. If the internal fuse is

blown (fails opens), it is most probable that there is a fault in the device. If this failure occurs, the device must be

checked in the factory. Caution: in two phase Input models, Double pole / Neutral Fusing.

On the secondary side: the devices are electrically protected against: Over Load, Over Voltage Output (typ.35

Vdc), and Short circuit automatically.

Short circuit and overload Protections Mode:

Depending on the users application loads, the ADEL Flex Line offers three types of protection modes which are

available by removing the plastic window and changing the Jumper to the desired setting as shown below:

(No Settings jumper for FLEX60xxA only Continuous Mode Condition)

1) HICCUP MODE (default factory Jumper setting)

General purpose mode, used for normal load.

In case of short-circuit or overloading, the

output current is interrupted. The device tries

again to re-establish output voltage and normal

condition about every 2 second till the problem

is cleared. .

2) MANUAL RESET (manual Restart by Operator)

This protection mode is particularly suggested

in applications where safety procedures require

that reset be carried out only by an authorized

person.

In case of short-circuit or overload, the output

current is interrupted. In order to restart the

output it is necessary to switch-off the input

circuit for about 1 – 5 minutes. .

3) CONTINUOUS OUTPUT MODE

In case of short-circuit or overload, the output

current is kept at high values with near zero

voltage. In case of short circuit the current can

reach up to 3 times the rated current at 60°C.

This protection mode is used to meet the

requirements of demanding loads such as

motors, solenoid valves, lamps, PLC with highly

capacitive input circuits and other loads with

marked transient overload behavior

The output of the device is electrically protected against overload and short circuit. For the nominal voltage and

nominal current at temperature condition, please see technical data. The device can supply at the nominal Current

without switching off. As the overloadincreases, the output voltage is reduced until zero.

Temperature Ratings

Surrounding air temperature 50 °C for FLEX60xxA, for the

other 60°C. At the temperature of 70°C the output current will

be 75% - 50% of In. The equipment does not switch off in case

of ambient temperature above 70°C or thermal overload. The

devices are protected for Over temperature conditions “worst

case”; in this situations the device Shut-down the output and

automatic restart when temperature inside fall.
