Power supplies for d.c. control circuits
Phaseo switch mode power supplies (continued)
3-phase and single-phase process supplies ABL-7U and ABL-7REQ:
b ABL-7UE
v power between 120 W (5 A) and 480 W (20 A),
v compact size,
v voltages between 3 x 380 V and 3 x 500 V,
v for use in industrial applications, for all in-line or continuous process equipment,
machine tools and injection presses, etc.
v suitable for use in automation system environments based on the Premium and
Quantum platforms, or in any automation system configuration requiring a c 24 V
supply.
b ABL-7UPS
v power between 120 W (10 A) and 960 W (40 A).
Identical to the ABL-7UE range, this power supply differs in that it includes a filter
(PFC) which means that it can be connected directly to the public mains supply, in
compliance with standard EN 61000-3-2. This product, for world-wide use, is UL
certified.
b ABL-7 REQ
v power between 120 W (5 A) and 240 W (10 A),
v compact size,
v can be connected to 2-phase input voltages between 380 V and 415 V, to replace
older power supplies connected by only two wires. Economical, more competitive,
yet with a smaller input voltage range it can, in certain cases, be used in place of the
3-phase versions.
Using c 24 V
b Using c 24 V enables so-called protection installations (PELV) to be built. Using
PELV is a measure designed to protect people from direct and indirect contact.
Measures relating to these installations are defined in publication NF C 12-201 and
in standard IEC 364-4-41.
b The application of these measures to the electrical equipment in machines is
defined in standard NF EN 60204-1 and requires:
v that the voltage used is below 60 V d.c. in dry environments and below 30 V in
damp environments,
v the connection of one side of the PELV circuit, or one point of the source, to the
equipotential protection circuit associated with higher voltages,
v the use of switchgear and control gear on which measures have been taken to
ensure "safety separation" between power circuits and control circuits.
b A safety separation is necessary between power circuits and control circuits in
PELV circuits. Its aim is to prevent the appearance of dangerous voltages in c 24 V
safety circuits.
b The reference standards involved are:
v IEC 61558-2-6 and EN 61558-2-6 (safety transformers),
v IEC 664 (coordination of isolation).
Telemecanique power supplies meet these requirements.
b Moreover, to ensure that these products will operate correctly in relation to the
demands of their reinforced isolation, it is recommended that they be mounted and
wired as indicated below:
v they should be placed on an earthed mounting plate or rail,
v they should be connected using flexible cables, with a maximum of two wires per
connection, and tightened to the nominal torque,
v conductors of the correct insulation class must be used.
b If the d.c. circuit is not connected to an equipotential protection conductor, an
earth leakage detector will indicate any accidental earth faults (please consult your
Regional Sales Office).
Operating voltage
b The permissible tolerances for the operating voltage are listed in publications
IEC 1131-2 and DIN 19240.
b For nominal voltage Un = c 24 V, the extreme operating values are from - 15 %
to + 20 % of Un, whatever the supply fluctuations in the range -10 % to + 6 %
(defined by standard IEC 38) and load variations in the range 0-100 % of In.
All Telemecanique c 24 V power supplies are designed to provide a voltage within
this range.
b It may be necessary to use a voltage measurement relay to detect when the
normal voltage limits are being surpassed and to deal with the consequences of this
(please consult your Regional Sales Office).
