Step down size, step up performance.

Save space and height while achieving high performance and reliability with power transformers from Advanced Components Industries.

We specialize in miniature, space-limiting and height-limiting transformers. And they're all encapsulated to provide enchanced electrical insulation. So, for about the same cost of an open-frame transformer, you get a device that better resists moisture, shock and vibration while offering improved heat transfer. We offer three lines of transformers, the Miniature Series, the Space Limiting SPK Series and the Height Limiting SPF Series. All three lines incorporate the split bobbin design and are c-UL and VDE approved.





















   
 

The airtight case for encapsulated transformers.

For more than 25 years, our encapsulated, or potted, transformers have proven so superior in meeting customer requirements that we no longer offer open-frame transformers.

Potted transformers are highly protected from environmental dangers. They provide:

  • Moisture Resistance: The potting compound guards the transformer in damp and humid environments, including wave soldering processes and wash rinses.
  • Mechanical Strength: The potting compound protects the wire and complete winding from accidental cutting, dirt entrapment, and other hazards, so potted transformers are perfectly suited for industrial environments
  • Shock and Vibration Resistance: The potting compound strengthens the grip of the pins, so the transformer requires no additional clamping on the PC board. All bobbins have up to 20 pin placement options. When applications require extreme shock and vibration resistance, we can add pins to further improve PC board adhesion.
  • Increased Heat Transfer: The potting compound conducts heat more efficiently than air in an open-frame transformer, which results in a higher power/volume ratio
 

In addition to these mechanical advantages, potted transformers offer an important electrical advantage over open frame transformers.

  • Enhanced Insulation System: Our potting process is performed under vacuum, eliminating any air gaps or pockets in the potting compound. Accordingly, testing agencies consider the potting compound an insulator. This reduces spacing requirements, resulting in smaller packages with better insulation.

High-potential testing and surge testing

We perform high-potential tests between windings of opposite polarities. We perform a 5,000 V RMS HiPot test on all of our transformers, and offer transformers HiPot tested to 15,000 V RMS. The insulation between secondaries is tested at 1,500 V RMS.

Our Impulse Surge Test, which simulates surges caused by lightning or power-factor correction, consists of a high voltage wave of up to 12,000 V RMS with a specified rise time and duration that is applied to the primary winding of the transformer (see IEEE C62.41). We specialize in miniature transformers that meet these requirements.
