Power supplies

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:

bABL 7UEQ

vpower between 120 W (10 A) and 480 W (20 A), v compact size,

v voltages between 3 x 380 V and 3 x 415 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 Modicon® Premium™ PLC and Modicon® Quantum™ PLC platforms, or in any automation system configuration requiring a c 24 V supply.

b ABL 7UPS and ABL 7UES

v power between 120 W (5 A) and 960 W (40 A).

Identical to the ABL 7UEQ 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.

b ABL 7REQ

v power between 120 W (5 A) and 240 W (10 A), v compact size,

v can be connected to 2-phaseinput 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.

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 grounded 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 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.

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).
