The power supplies FLEX Series can be used in areas from
extreme industrial environment, and complies with the latest
technical standard. Before working with the unit, read these
instructions carefully and completely. All these power supplies
are single output, IP20, have Mounting DIN Rail IEC
60715/TH35. Class 1 isolation devices suitable for SELV and
PELV solutions.
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!

Input - Output power connection:
Easy Parallel connection ON
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 overload increases, 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.
