Things To Consider

Cross-Reference Alternatives

Acme Electric's MPNs cross individual references to the equivalent Functional Devices Inc / RIB and Square D model numbers. So, if you are looking for competitor items that are either out of stock or obsolete, chances are Raptor Supplies has the equivalent Acme Electric transformers available.


Acme Electric transformers are available in control, current, isolation, lighting, single-phase and three-phase types. These transformers and related accessories are large and small in size & therefore require careful packaging as some products might get damaged while shipping. Hence, they are delivered by courier shipment and air freight for minimum downtime.

About Acme Electric

The Acme Electric product line includes AC line reactors, transformers, DC power supplies and battery chargers. The extensive Acme transformer catalogue comprises buck-boost, drive-isolation, harmonic mitigation, industrial control, low-voltage lighting, & distribution and non-linear load transformers. The brands buck-boost transformers are ideal for single phase applications and feature NEMA 3R enclosure rating to protect from dirt or rain. These transformers come equipped with low-maintenance copper terminals and are available in power ratings ranging from 50 to 5000 VA. Acme Electric energy efficient transformers minimise the power drawn from generating stations for less smog & greenhouse gas emissions. These three-phase transformers are offered in 30k, 45k, 75k, 150k and 225k VAC voltage configurations. Choose from a wide range of these products and related accessories, such as replacement motors and jumper links, on Raptor Supplies.

Panel-Tran Zone Power Centers

Panel-Tran Zone Power Centers

They are pre-wired combination units that save space, time and money in harsh industrial locations. These products include a shielded dry-type transformer, primary & secondary breaker disconnect and a secondary power panel in a NEMA 3R-rated enclosure to protect the system from dirt, dust or rain.

Non-Linear Load Isolation Transformers

Non-Linear Load Isolation Transformers

They generate high levels of harmonic current. By using winding techniques, they reduce generated eddy current losses. These UL-listed & CSA-certified units come with pre-installed weather shields for improved flexibility. They have secondary and primary terminals with lugs for easy & quick connecti...

Acme Electric Competitive Advantages

Wound Cores and Strip Windings

Wound Cores and Strip Windings

For the least amount of eddy current losses feasible, strip windings are used to wind all Acme DITs over 7.5 kVA. This innovative design operates quietly and with very little loss of operational expenses in comparison to the alternative structures.

Copper Terminations

Copper Terminations

All Acme DITs have copper terminations. The bonding method that converts aluminium strip coil conductors into copper terminations is known as "Koldwelding".

Frequently Asked Questions

What is the difference between an autotransformer and an isolation transformer?

An autotransformer is a transformer with an electrical connection between the primary input and secondary output. Whereas the primary input and secondary output of an isolation transformer, also known as an insulating transformer, are completely electrically separated from one another.

What is the life expectancy of a buck-boost transformer?

The life expectancy of a buck-boost transformer is 30 or more years.

Are buck-boost transformers as quiet as standard isolation transformers?

Yes. As compared to an isolation transformer that can handle the same load, an auto-connected buck-boost transformer will be quieter. Smaller transformers are quieter than larger ones, therefore the isolation transformer would need to be physically bigger than the buck-boost transformer.
