ABB has significantly enlarged its range of switch-mode power supply devices (SMPS). Supplementing the existing range of tried and tested SMPS products of the CP series for nominal currents of 0.3A up to 20A, there are now new CP-S and CP-C series for the range between 5 to 20A available.

The SMPS devices of the CP-C series are characterized by their modular, plug-in functional modules that extend the functionality of the devices tailored to the requirements of the customer. The CP-C MM signal module for example monitors the input and output voltage, and has a remote-OFF function. More plug in modules are under preparation.

There are also manifold applications for the CP-S devices that – while offering the same modern and powerful technology – dispense with some of the extra features of the CP-C series.

All power supply units of the CP, CP-S and CP-C series are primary SMPS: they guarantee the best possible efficiency (>88%), minimized losses, environmental compatibility and cost efficiency.

Characteristics:
CP-S range
• Selectable input voltage 85-132VAC/184-264VAC, 220-350 V DC
• Fixed output voltage

CP-C range
• Autorange input 85-264VAC, 100-350VDC
• Adjustable output voltage 22-28VDC
• PFC (power factor correction)

The new CP-S and CP-C range power supplies feature power reserve of up to 50%. The 5A and 10A models have pluggable, double connection terminals, and LED indication “OUTPUT OK”. All of them are CE marked, the C-Tick mark and the cULus (508) and UL60950 approvals are under preparation.

Power without any doubts

Modern power supplies are a vital component in most areas of energy management and automation technology. The new CP-E range power supplies are the youngest members of the ABB power supply family. This range offers types with output voltages from 5 V DC to 48 V DC at output currents of 0.625 A to 3 A.

A high thermal efficiency corresponding with low power and heat dissipation, allow the operation without forced cooling. Functionality has been enhanced while the number of different types has been considerably reduced.

All power supplies of the new CP-E range are approved to all relevant world-wide standards (cULUS, IEC/EN 60950, etc.) and have both CE and C-TICK marks.

Characteristics of the CP-E range
• Output voltage 5 V, 12 V, 24 V, 48 V DC
• Adjustable output voltages
• Output current 0,625 A, 0,75 A, 1,25 A, 2,5 A, 3 A
• Power range 18 W, 30 W, 60 W
• Auto range input 100…240 V AC range (85…265 V AC, 90…375 V DC)
• High efficiency of up to 87…89 %
• Low power dissipation and low heating
• Free convection cooling (no forced cooling with ventilators)
• operating temperature range –10…+70°C
• Open-circuit, overload and short-circuit stable, automatic recovery
• Integrated input fuse
• U/I characteristic curve (fold-forward behaviour at overload – no shutdown) for devices > 18 W
• Redundancy unit CP-A RU offering true redundancy
• Status LED “OUTPUT OK”
• DC OK output (transistor) for 24 V devices (> 18 W)

Do you give your motors a kick-start?  Or do you accelerate them nice and smoothly?  If you have a large motor, the answer is obvious: You install a softstarter to protect your electrical network.  But… what do you do if your motor is medium-sized or small?  You either start Direct-On-Line.  Or you install a Y/D starter. And keep your fingers crossed.

It doesn’t have to be that way any longer.  ABB is now introducing a state-of-the-art range of small, compact softstarters that covers applications from 3A up to 45A.  They are designed to meet our customers’ surveyed requirements:  “Better performance than Y/D… reliability and quality… tight dimensions… easy installation…possibilities of communication… and all of this, of course, at an attractive price!”  In brief, it’s a brand new concept in compact softstarters – it’s really a smart Starter!  Power and Productivity.

To provide convenient cost-effective solutions for electrical distribution applications where a switched neutral is needed, Moeller Electric has expanded its popular and versatile range of xStart contactors to include new four-pole models. The new DILMP models cover AC1 current ratings from 22A to 200A in just four frame sizes, the new four-pole contactors feature identical dimensions for AC- and DC-operated versions, thereby simplifying panel design and construction.

Ideal for use in mains/standby changeover, heating control, and distribution systems for IT installations, xStart four-pole contactors, like their three pole counterparts, have specially designed low consumption coil assemblies.

Not only do these innovative coil systems reduce heating in the control panel and energy consumption, they also make it possible for contactors up to 45A to be controlled directly from inexpensive low current PLC outputs, thereby eliminating the need for inconvenient interposing relays or costly high-power output modules.

The use of the contactors with PLCs is further simplified by the integrated suppressor which is included as standard in all DC-operated versions.

The new contactors feature space-saving compact construction, are designed to make wiring fast and easy. Access to the coil terminals is at front-plate level and, for additional convenience and safety, double-chamber screw-clamp terminals are used throughout.

Moeller Electric offers a wide range of accessories for use with its new four-pole xStart contactors. These include mechanical interlocks for vertical and horizontal configurations, which need no additional space to be allowed between the contactors; auxiliary contacts in standard and early-make/late-break versions; suppressors for AC-operated types; and insulating shrouds.

To maximise user convenience, the new four-pole contactors use the same accessories as three-pole models in the xStart range.

Manufactured to the highest standards, xStart contactors are designed to provide maintenance-free operation for a mechanical life of at least 10 million operations. They comply with all relevant sections of IEC60947, as well as with appropriate UL and CSA requirements. In addition, they carry the CE marking.

Crydom Solid State Relays (SSRs) are utilized in numerous medical applications. Crydom SSRs are used to control motors in hospital beds, examination tables, and rehabilitation equipment. SSR’s are also widely used for heating controls in sterilization equipment, blood warming units, and incubators.

Since Crydom SSRs utilize silicon for switching loads and therefore have no contacts that arc, contact contamination and the danger of sparking are eliminated. Coupled with an epoxy-filled encapsulation, the Crydom SSR is resistant to steam and other sterilization techniques.

The recent introduction of the Crydom MC series of SSR/controllers is an all in one solution that includes both a controller and a Crydom SSR in one package to control temperature, phase control, or soft start, soft stop functions.

Crydom Solid State Relays (SSRs) are utilized in the lighting industry in a wide range of applications. Beside the obvious on-off supply control, or for the remote power switching points for centralized automated control, Crydom SSRs find widespread use in high power dimming systems for theatrical, industrial and residential applications, as well as airport lighting controls, parking lot lighting, safety lights and energy saving systems for commercial and industrial lighting.

The Crydom MCPC series of microprocessor based proportional controller/SSR modules significantly reduce the amount of design effort and components required to incorporate phase angle dimming control in lighting systems while improving reliability and life.
