NK Transformers

The Flexible Coil Design allows the cable to surround multiple conductors or bus assemblies regardless of shape and eliminates the magnetically permeable core of standard current transformers while providing excellent isolation, sensing only the magnetic field of the phase inside the loop. The CTRC can be used in any power monitoring application. CTRC Current Transformers use the Rogowski coil as the first step in power monitoring.

Weidmuller SAI Cables

Male Plugs & Female Sockets can be assembled to suit individual customer requirements for connecting cables. The cable sheathing is of PUR (polyurethane) and is suitable for use with cable carrier systems. Plugs and cables are in neutral black. Many applications with sensors require suitable connecting cables. The connecting cables are available in different designs. The M12/M8 plug-in connectors are available in straight and 90° versions and also with LEDs.

Buck-Boost Transformers

Buck-Boost transformers are small, single phase, dry type distribution transformers designed and shipped as insulating/isolating transformers. They have a dual voltage primary and a dual voltage secondary. These transformers can be connected for a wide range of voltage combinations. The most common use is to buck (lower) or boost (raise) the supply voltage a small amount, usually 5 to 27%. Buck-boost transformers are in compliance with NEC Article 210-9, Exception 1 when field connected as an autotransformer.

If you are looking for Sola Buck-Boost Transformers, please call us on (800) 894 - 0412 or email us at info@clrwtr.com we will do our best to help you find the HS19B50 Transformer that you are looking for at the most competitive prices possible. If you are searching for HS19F1.5A Transformer technical information (data-sheets) please use the datasheets or product selection guide page links.

The major advantages of Buck-boost transformers are their low cost, compact size and light weight. They are also more efficient and cost less than equivalent isolation transformers. When connected as an autotransformer, they can handle loads up to 20 times the name plate rating. A buck-boost transformer is the ideal solution for changing line voltage by small amounts.

When a buck-boost has the primary and secondary windings connected, per recommended instructions, it becomes an autotransformer. Now only the secondary windings are transforming voltage and current. The majority of the kVA load passes directly from the supply to the load. This is the reason buck-boost transformers can supply a load with a much larger kVA rating than the nameplate indicates.

SolaHD buck-boost transformers are designed to supply power to low voltage lighting circuits, control panels or other systems requiring 12, 16, 24, 32, or 48 Volts. When connected as an insulating transformer (by following the wiring diagram located after the specification tables on the inside of the transformer case), the transformer's capacity matches the nameplate kVA rating.

SolaHD buck-boost transformers are also suited for low voltage landscape lighting. They are UL listed for outdoor service and their compact size makes them the perfect solution for providing power to accent lighting applications. When using dimmers for low voltage lighting applications, use dimmers on the output of the transformer that are designed and rated for use with magnetic loads. We strongly recommend contacting the dimmer manufacturer for advice on your specific lighting application.

Selection Steps

  1. Input Line Voltage - Measure the supply voltage with a voltmeter.
  2. Voltage Required for the Load - Check the load equipment to determine the voltage requirement.
  3. kVA or Ampere Rating of the Load - Find either the load kVA or the load amperage requirements. This information is listed on the nameplate of the load equipment.
  4. Frequency - Either 50 or 60 Hz. The frequency of the transformer must match the frequency of the load.
  5. Number of Phases - Single or three phase line and load must match. (A transformer cannot convert single to three phase.)

A common application is to make a single phase connection from a three phase supply by using one phase of the three phase supply circuit. Be careful not to overload that phase of the three phase supply. For buck-boost applications the supply must provide load kVA - not just the nameplate rating of the buck-boost.
