Supplying quality transformers since 1985
Transformers types we manufacture
A transformer is a device used for increasing or reducing the voltage of an alternating current. At Shreejee Electronics, we manufacture specialty transformers for a variety of industries, including OEM, instrumentation, imaging, medical, military, and aerospace.
Our specialty transformers include high voltage universal windings, line voltage transformers, high frequency transformers, and step up and step down transformers up to 100 KVA. Some of the different varieties of custom transformers we manufacture include:
High Frequency Transformers
High frequency transformers are useful when noise reduction, increased
efficiency, and limited space are important to your application. High frequency transformers can deliver extraordinary power in a small unit.
They are manufactured with advanced core materials, including ferrite and powdered iron and are available in a range of mounting types such as SMD, thru-Hole and flying leads.
Torodial Transformers
Toroidal transformers are known for their high efficiency, excellent load regulation,
and very low emitted EMI. Our toroidal transformers can handle wattage ratings from less than 10 VA to greater than 2000 VA.

| Applications | audio, lighting, power, and medical applications |
| Range | 14W-44W |
| Core Material | Ferrite Core (EE, ETD, …) and Iron Core |
Buck boost Transformers
Buck boost transformers are designed to be able to adjust voltage within a
limited range. They are most often used to precisely match the voltage of a power supply. For example, a buck boost transformer can be used to adjust the voltage from a power supply to the exact voltage required by a product. Buck boost transformers are also known as step up and step down transformers.
We manufacture buck boost transformers in single or three phase applications with standard or multi-tap configurations.

| Applications | low power lighting, uninterruptible power supplies for computers, industrial lighting that runs at higher voltages |
| Range | 14W-44W |
| Core Material | Ferrite Core (EE, ETD, …) and Iron Core |
Three Phase Transformers
These transformers are primarily used to step up or step down voltages in three
phase power industrial machine applications. While single phase transformers could be bundled and used for these systems, using a three phase transformer is generally more advantageous. They use less material, weigh less, and are usually smaller than a single phase bundle would be.

Isolation Transformers
Isolation transformers are used to prevent signal interference and to direct power
between independent circuits that cannot be directly connected. Many applications require the circuit in contact with user be “isolated” from the main power circuit.
At Shreejee Electronics, our UL E160724 listing for insulation allows us to apply the UL mark for temperature ratings for 130 to 220 deg celsius.

Instrument Transformers
These transformers are used to provide analog information to help monitor,
control, operate, and protect the power system to which they are connected. We can manufacture instrument transformers in a range of sizes, from compact to broad mount capabilities.
Our designers and engineers will work with you to develop a transformer with the correct voltage, VA rating, and physical size requirements you need.

Pulse Transformers
Pulse transformers are generally used to transmit information through analog and digital
signals. They are designed to produce a specific rectangular waveform.
