The Customer

Ampcontrol: Leading the Future of Stand-Alone Power Systems

Ampcontrol is at the forefront of off-grid energy innovation, engineering scalable, sustainable Stand-Alone Power Systems (SAPS) for remote communities and critical sites. These units replace aging grid infrastructure with clean, self-sufficient power solutions using solar PV, batteries, and intelligent energy management.

Working alongside utilities such as Western Power and key technology partners, Ampcontrol deploys SAPS across Western Australia—delivering safe, reliable electricity to areas previously reliant on costly and failure-prone poles-and-wires systems. For transformer supply, they rely on SES.

The Challenge

Off-Grid Systems Need Durable, Noise-Free Voltage Conversion

Each SAPS unit required a transformer that could:

Step up 240V to 480V for low-loss transmission
Operate reliably in isolated, harsh environments
Provide clean, stable output to household and industrial appliances
Seamlessly integrate with solar, battery storage, and inverter systems
Meet strict safety and performance standards for utility-grade deployment

A custom solution was needed—one built specifically for SAPS.

The Solution

SES Delivers Purpose-Built Isolation Transformers for SAPS Rollouts

Since 2021, SES has supplied over 100 single-phase isolation transformers, tailored to meet the performance and reliability demands of SAPS in the field.

Transformers Supplied:

87 x SD8460 — 240V/480V @ 15kVA
20 x SD8461 — 240V/480V @ 25kVA
6 x SD8027 — 240V/480V @ 20kVA

Key Features:

Voltage step-up for efficient off-grid distribution
Low-noise, reliable operation to protect sensitive appliances
Compact, rugged design for field deployment
Built for renewable integration—compatible with solar and battery platforms
Fully compliant with AS/NZS 60076 and AS/NZS 61558

All units are manufactured locally by SES, with flexible lead times and full technical support.

The Outcome

Reliable Off-Grid Power for Remote Communities and Infrastructure

SES transformers are now powering a growing network of SAPS installations across Western Australia, helping reduce carbon emissions, improve energy access, and lower maintenance burdens for utilities.

Clean, stable power without reliance on the grid
Improved resilience against weather and wildlife-related faults
Scalable deployment to expand renewable energy access
Trusted partnership with Ampcontrol and their delivery teams

Deacam Operations Mgr

Nothing short of exceptional Deacam P/L were engaged to perform various project works associated with the Bayswater Level Crossing Removal (LCRP). Quick turnaround from suppliers were paramount to achieving project deadlines. After approaching multiple transformer manufacturing companies, S.E.S ( Southern Electronic Services) were the only company who were able to guarantee the manufacturing lead time required. A 60 kva transformer ordered 25/11/16 and delivered 2/12/16 was nothing short of exceptional considering we were receiving indicative lead times from other manufacturers of up to 30 days. We will be happy to engage SES again.

Duncan Massie

Director

Nothing too big or small Monex GeoScope has been using SES for over a decade now. We are a small manufacturing company making specialist acquisition system for which we need precision components. SES provide our transformers, inductors. We have limited runs and our products must be extremely repeatable and that is exactly what we receive from SES. SES have also provided invaluable advice and insight into designing induction coils with unique properties again with limited quantities. Given our size we have never felt that we are not important to SES; they provide a competitive quote and timeframe and adhere to it. We have and continue to find dealing with SES extremely pleasing

Scott Callander

Production Manager

Highest quality products Southern Electronic has been the main supplier for our transformer coils for over 10 years. Our transformers come with a four-year warranty period; we are able to offer this due to the quality workmanship of Southern Electronic. Their staff have always been there to help us with any technical enquiries, and their service has always been great. I would recommend Southern Electronic to anyone looking for transformers/winding service.
