Power supplies for d.c. control circuits
Phaseo® regulated switch mode power supplies
Phaseo switch mode power supplies (continued)
3-phase and single-phase process supplies ABL 7U and ABL 7REQ:
bABL7UEQ
vpower between 120 W (10 A) and 480 W (20 A),
vcompact size,
vvoltages between 3 x 380 V and 3 x 415 V,
vfor use in industrial applications, for all in-line or continuous process equipment,
machine tools and injection presses, etc.
vsuitable for use in automation system environments based on the Modicon®
Premium™ PLC and Modicon® Quantum™ PLC platforms, or in any automation
system configuration requiring a c 24 V supply.
bABL7UPS and ABL 7UES
vpower between 120 W (5 A) and 960 W (40 A).
Identical to the ABL7UEQ range, this power supply differs in that it features an
extended input voltage range from 3 x 400 to 3 x 520 V and includes a filter (PFC)
which means that it can be connected directly to public mains supplies, in compliance
with standard EN 61000-3-2. This product, for world-wide use, is UL and CSA
certified.
bABL7REQ
vpower between 120 W (5 A) and 240 W (10 A),
vcompact size,
vcan 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
bUsing 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.
bThe application of these measures to the electrical equipment in machines is
defined in standard NF EN 60204-1 and requires:
vthat the voltage used is below 60 V d.c. in dry environments and below 30V in
damp environments,
vthe connection of one side of the PELV circuit, or one point of the source, to the
equipotential protection circuit associated with higher voltages,
vthe use of switchgear and control gear on which measures have been taken to
ensure "safety separation" between power circuits and control circuits.
bA 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.
bThe reference standards involved are:
vIEC 61558-2-6 and EN 61558-2-6 (safety transformers),
vIEC 664 (coordination of isolation).
Telemecanique® power supplies meet these requirements.
bMoreover, 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:
vthey should be placed on an grounded mounting plate or rail,
vthey should be connected using flexible cables, with a maximum of two wires per
connection, and tightened to the nominal torque,
vconductors of the correct insulation class must be used.
bIf the d.c. circuit is not connected to an equipotential protection conductor, an
ground leakage detector will indicate any accidental ground faults (please consult
your Regional Sales Office).
Operating voltage
bThe permissible tolerances for the operating voltage are listed in publications
IEC 1131-2 and DIN 19240.
bFor 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.
bIt 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).
