No matter your specific application or project requirements, you'll find the perfect power supply transformer with RS to meet your needs.

What is a Transformer Power Supply?

A power transformer is an electrical device that efficiently transfers electrical energy from one circuit to another through electromagnetic induction. Power supply transformers change the voltage and current levels while maintaining the same frequency, allowing for safe and efficient power distribution.

Power transformers are essential in both residential and industrial settings, enabling the use of various electrical devices and machinery. Common uses include stepping down high voltages from power grids to usable levels in homes or stepping up voltages for long-distance transmission.

Power Supply Transformer Types

At RS Australia, we offer a range of power transformer types:

Audio Power Transformers

Audio power transformers are used to increase and decrease voltage in amplifiers and high-frequency audio and voice circuits.

Autotransformers

Also known as step-down power transformers, autotransformers are small, cheap, and light due to only having one coil, unlike those with a secondary winding coil.

Chassis Mounting Transformers

These power transformers come in different sizes with holes for mounting to a chassis. Chassis mounting transformers can be used for a wide variety of applications where secure and robust installation is crucial, including audio equipment, industrial machinery, and control panels.

Current Transformers

These power transformers measure the current of another circuit by producing a proportional current in their secondary winding. This allows for safe and accurate monitoring of high currents in power systems without direct contact.

DIN Rail & Panel Mount Transformers

These power transformers can be mounted to a flat surface, panel, or DIN rail via mounting holes.

LAN Ethernet Power Transformers

LAN Ethernet power transformers enable safe and reliable power and data transmission over Ethernet networks through isolation and signal conditioning.

Lighting Transformers

Lighting transformers are power transformers that are specifically designed to work with lighting, most commonly dimmer switches.

PCB Power Transformers

These printed circuit board transformers control the voltage or current moving through the board.

Safety Site Power Transformers

Safety site power transformers provide crucial protection by isolating machinery and equipment from the main power supply, minimising the risk of electrical shocks and overloading in demanding environments.

Switch Mode Power Supply (SMPS)

Switch mode power supply transformers are used primarily in PCs to switch from AC or DC to DC power.

Telecom Power Transformers

Commonly used in homes, telecom power transformers step down high voltages from power lines to safe levels suitable for household appliances and electronics, providing essential voltage isolation before transmission.

Toroidal Transformers

Toroidal power transformers come in the shape of a ring or doughnut and are ideal for applications where space is limited and noise reduction is important.

Wall Mount Power Transformers

Often used in hazardous locations or harsh industrial environments, these power supply transformers are designed for secure and convenient installation on walls or vertical surfaces, ensuring reliable power delivery.

Common Applications of Industrial Power Transformers

Industrial power transformers play a crucial role in the following sectors, ensuring the efficient and safe distribution of electricity for a wide range of applications:

• Discrete manufacturing: Power supply transformers are essential in powering machinery and equipment on assembly lines, providing the necessary voltage levels for various processes, such as welding, cutting, and automation.
• Process manufacturing: In industries like chemical processing and food production, power transformers ensure reliable power supply for pumps, motors, and control systems, enabling continuous operation and precise control of manufacturing processes.
• Energy & utilities: Power transformers are the backbone of the electrical grid, stepping up or down voltages for efficient transmission and distribution of electricity across vast distances, ensuring power reaches homes and businesses.
• Facilities intralogistics: Industrial transformers play a vital role in material handling and warehouse operations, powering conveyor systems, automated storage and retrieval systems (AS/RS), and other equipment that facilitates the movement of goods within facilities.

Key Features to Consider When Buying Transformer Power Supply

When looking for a power supply transformer, you should first determine the required input and output voltage levels to ensure compatibility with your electrical system and the devices it will power. Next, consider the power rating (kVA or VA) needed to handle the expected load, leaving some headroom for future expansion. Then, decide on the type of transformer needed, such as PCB mounting, chassis mounting, or DIN rail mounting. This should be chosen based on your installation requirements and space constraints.

Additionally, pay attention to factors like efficiency, operating temperature range, and safety features, such as overcurrent and overtemperature protection. Finally, consider the brand reputation and warranty offered to ensure you're investing in a reliable and durable power supply transformer.

Maintenance Tips for Extending the Life of Power Transformers

Regular upkeep is key to ensuring the longevity and peak performance of your power supply transformers. Here are some practical maintenance tips you should follow:

• Regular inspections: Conduct routine checks for signs of wear or damage, including cracks, leaks, or corrosion.
• Cleaning: Regularly remove dust and debris to prevent overheating.
• Temperature monitoring: Monitor the operating temperature for any abnormalities.
• Oil level checks: If applicable, check oil levels regularly.
• Sensory checks: Be alert for unusual noises, vibrations, or odours.
• Prompt action: Address any issues immediately to prevent further damage.
• Routine maintenance: Adhere to a maintenance schedule to maximise transformer lifespan and minimise downtime.

Accessories and Components for Power Supply Transformers

We also offer a range of accessories and components to complement your industrial power transformers. These include chip and transformer-line baluns for impedance matching and signal balancing in communication systems, coil formers for creating custom inductors, mounting kits for secure installation, terminal covers for protection, and ferrite cores for suppressing electromagnetic interference.

Additionally, we offer variac brushes, connectors, dials, and knobs for variable transformers, providing precise voltage control. These accessories enhance the functionality, safety, and ease of use of your power transformers, providing additional flexibility and convenience for your applications.
