Power supplies for d.c. control circuits
Phaseo® modular regulated power supplies
The ABL 7RM range of power supplies is designed to provide the d.c. voltage
necessary for the control circuits of automation system equipment. Comprising
3products, this range meets the needs encountered in industrial, commercial and
residential applications. These single-phase, modular, electronic switch mode power
supplies provide a quality of output current which is suitable for the loads supplied
and compatible with the Zelio® Logic range, making them ideal partners. Clear
guidelines are given on selecting the upstream protection devices which are often
used with them, and thus a comprehensive solution is provided that can be used in
total safety.
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:
bvery compact size,
bintegrated overload, short-circuit, overvoltage and undervoltage protection,
ba very wide range of permissible input voltages, without any adjustment,
ba high degree of output voltage stability,
bgood performance,
bconsiderably reduced weight,
ba modular format allowing integration into panels.
Phaseo power supplies deliver a voltage which is precise to 3%, whatever the load
and whatever the type of mains supply, within a range of 85to 264 V for single-
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.
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.
These power supplies are designed for direct mounting on 35 and 75 mm 7 rails, or
on a mounting plate using the retractable mounting lugs.
These power supplies are single-phase and three references are available:
bABL 7RM2401 (24 V c/1.3 A),
bABL7RM24025 (24 V c/2.5 A),
bABL 7RM1202 (12 V c/1.9 A).
