Power supplies for d.c. control circuits
Phaseo ® regulated switch mode power supplies
ABL 7 power supplies
The ABL 7 range of power supplies is designed to provide the d.c. voltage necessary
for the control circuits of automation system equipment. Split into three families, this
range meets all the needs encountered in industrial, commercial and residential
applications. Single-phase or 3-phase, of the electronic switch mode type, they
provide a quality of output which is suitable for the loads supplied and compatible
with the mains supply available in the equipment. Clear guidelines are given for
selecting protection devices which are often used with them and thus a
comprehensive solution is provided, which can be used in total safety.
Phaseo switch mode power supplies
These switch mode power supplies are totally electronic and regulated. The use of
electronics makes it possible to significantly improve the performance of these power
supplies, which offer:
- very compact size,
- integrated overload, short-circuit, overvoltage and undervoltage protection,
- a very wide range of permissible input voltages, without any adjustment,
- a high degree of output voltage stability,
- good performance,
- LED indicators on the front panel.
Phaseo power supplies are available in single-phase and 3-phase versions. They
deliver a voltage which is precise to 3%, whatever the load and whatever the type of
mains supply, within a range of 85 to 264 V for single-phase, or 360 to 550 V for
3-phase. Conforming to IEC standards and UL and CSA certified, they are suitable
for universal use. The inclusion of overload and short-circuit protection makes
downstream protection unnecessary if discrimination is not required.
ABL 7 RE and ABL 7 RP supplies are also equipped with an output undervoltage
control which causes the product to trip if the output voltage drops below 19 V, in
order to ensure that the voltage delivered is always usable by the actuators being
supplied. All the products are fitted with an output voltage adjustment potentiometer
in order to be able to compensate for any line voltage drops in installations with long
cable runs. Most of our power supplies are designed for direct mounting on 35 and
75 mm 7 rails.
These power supplies are available in single-phase and 3-phase versions and are
split into three families:
Compact single-phase supply ABL 7CEM:
b power less than or equal to 30 W (1.2 A),
b compact size,
b for all low power equipment,
b suitable for use in automation system environments based on the Nano
™ PLC and
Twido ® PLC platforms, or in any automation system configuration requiring a c 24 V
supply.
Universal single-phase supplies ABL 7RE and ABL 7RP:
b ABL 7RE
v power between 48 W (2 A) and 240 W (10 A),
v compact size,
v for all machine equipment,
v suitable for use in automation system environments based on the Micro
™ PLC and
Modicon ® Premium ™ PLC platforms, or in any automation system configuration
requiring a
c
24 V supply.
b ABL 7RP
v power between 60 W and 240 W (10 A),
v output voltage available:
c
12, 24 and 48 V depending on version ,
v input filter (PFC) for commercial and residential environments (conforming to
standard EN 61000-3-2),
v two operating modes possible for handling of overload and short-circuit faults:
- "AUTO" mode which provides automatic restarting of the power supply on
elimination of the fault,
- "MANU" mode which requires manual resetting of the power supply to restart.
Resetting is achieved by switching off the mains power.
