Australian-Made. Built to Last
All Southern transformers are locally designed and manufactured for long service life, with full compliance to Australian Standards.
Custom-Built for Industrial Demands
From commercial industries to major sectors, we tailor each transformer to meet the real-world needs of your application – no limitations.
Delivered to Your Schedule without Compromise
We understand project timelines matter – Southern delivers transformers to meet your schedule, fast or slow, without cutting corners.
5-year Warranty, 25+ year design life
Every transformer is designed and built to operate continuously at rated power for 25+ years, backed by an industry-leading standard 5-year warranty.
Designed for Stand-Alone Power Systems (SPS)
With decades of experience, SES offers split-phase transformers engineered for off-grid, battery-based, and hybrid renewable power systems, where a stable, dual-voltage output is required from a single energy source.
Commonly used in SPS, our transformers deliver a balanced energy supply and seamless integration with switchboards, loads, or inverter-based systems. We’ve supported hundreds of installations across the country, so you can trust that our team will deliver consistent quality.
Typical SPS Isolation Split Phase Design Range
- Voltage: 240V primary to 480V centre tapped secondary (240V 0 240V)
- Power Rating: 10kVA to 50kVA
- Cooling: Dry-type, ANAN
- Enclosures: Open (IP00), Ventilated (IP23), or Weatherproof (IP65)
Designed for High Efficiency & Minimal Losses
Every SES split-phase transformer is carefully engineered to offer:
Efficiency First
Optimised for low no-load losses, reducing parasitic drain on battery-based systems.
Core Quality
High-grade core steel minimises eddy current and hysteresis losses, optimising for longer system runtime.
Thermal Precision
Precision-wound enamelled copper windings to reduce I²R losses, offering less heat build-up.
Verified Results
Performance and losses are verified through routine factory testing to ensure better overall system performance.
Custom Capability Range
We also manufacture split-phase transformers outside typical SPS specs, designed and measured to match your exact requirements:
- Input/Output Voltages: Any voltage up to 3.3kV
- Power Ratings: Up to 500kVA
- Frequency: 50Hz or 60Hz
- Mounting Options: Floor, wall, skid base
- Cooling: Natural air, forced air, or custom solutions
- Enclosures: Custom IP ratings and coatings available
- Configuration: Isolation or autotransformer type

What Clients Say About Us
Your Split Phase Transformer Questions
If you have a question that is not listed here, please contact us – we’re always happy to help.
SES uses dry-type, air-natural split-phase transformers. Without oil or active cooling, they offer safer, simpler, and more reliable performance in harsh conditions. Beyond the performance benefits, they also require minimal maintenance.
Learn more about stand-alone power solutions here.
Our transformers are designed with durability in mind. Transformers are designed, built and tested to perform continuously for at least 25 years under normal operation, but some customers have had SES transformers in operation for over 40 years.
In most cases, yes. At SES, we can tailor your power solutions to seamlessly integrate with your existing setup.
If you have any other questions, don’t hesitate to contact our experienced team today.
