SLC30-IPS Combination Display Lights with control units combine display lights with control units such as pushbuttons, illuminated pushbuttons, selector switches and keylock selector switches. This results in savings of both space and installation time, since mounting separate switches becomes unnecessary. SLC30-IPS combination display lights can be custom built to meet your specifications. Available with incandescent or Superbright LED illumination.


NK Technologies ProteCT series current transformers are intended for use with APT and APO/APN Series power transducers. ProtectCT low voltage output current transformers provide easy sensing of current on three-phase applications with the added safety of a 333 mV output secondary. Available in split-core case as standard.

Sola Hevi Duty General Purpose Ventilated Distribution Transformers Distributor

The Energy Policy Act of 2005 (H.R. 6) requires Distribution Transformers manufactured after January 1, 2007 to meet specific energy efficiency requirements. EPAct 2005 defines the term "distribution transformers" as any transformer which:

  • Has an input voltage of 34.5 kV or less
  • Has an output voltage of 600 V or less
  • Is rated for operation at a frequency of 60 Hz
  • Has a capacity of 10 kVA to 2500 kVA for liquid-immersed units and 15 kVA to 2500 kVA for dry-type units

If you are looking for Sola 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 Constant Voltage Transformer that you are looking for at the most competitive prices possible.

SolaHD Buck-Boost Single-Phase Three-Phase Dry-Type Distribution Transformers Distributor
1-Phase & 3-Phase Buck-Boost

Sola/Hevi-Duty 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, the transformer's capacity matches the nameplate KVA rating. Sola Hevi-Duty 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 applications, use only dimmers designed and rated for use with magnetic loads.
