The PAC STIS-2400 is an Australian-engineered 2400W isolated toroidal step-down transformer designed to safely power high-draw 120V US/Canadian and 100V Japanese appliances, espresso machines, power tools, and high-end audio setups on Australian 240V mains. Built with physical galvanic isolation, dual dedicated outlets (1 x 100V, 1 x 120V), and rated for 2400W continuous 24/7 duty, it delivers clean, isolated power while operating on standard Australian 10A/15A circuits. Backed by PAC's 2-Year Australian Replacement Warranty.
PAC Toroidal Voltage Converters — High-Capacity Clean Power with Galvanic Isolation
Deliver clean, isolated power to your heavy-duty 100V Japanese and 110V–120V North American equipment with the PAC 2400W Isolated Toroidal Step-Down Transformer (SKU: STIS-2400).
Designed for demanding commercial, workshop, audio studio, and laboratory environments, the STIS-2400 incorporates true galvanic isolation between the Australian 240V mains input and low-voltage outputs. By eliminating shared neutral connections and ground loops, it prevents electrical interference, isolates sensitive circuits from line surges, and delivers clean AC power with whisper-quiet operation.
Key Features:
- True Galvanic Isolation: Fully separated, double-insulated primary and secondary windings protect sensitive electronics, eliminate 50Hz audio hum, and shield against mains voltage spikes.
- Dual Output Outlets: Includes 1 x 100V (optimised for Japanese 100V gear) and 1 x 120V (USA/Canada) for simultaneous or dedicated operation.
- Maximum 2400W Continuous Output: Heavy-gauge pure copper toroidal windings deliver 2400 Watts continuous power 24/7 without thermal throttling.
- Standard Australian Circuit Ready: Engineered to deliver maximum continuous wattage achievable on standard Australian 10A/15A domestic supply lines.
- Triple Safety Protection: Resettable front-panel miniature circuit breaker (MCB), internal thermal protection, and line fuse protection.
- Australian Standards Compliant: ACMA and EESS Responsible Supplier registered for Australian electrical safety.
- 2-Year Replacement Warranty: PAC commercial-grade engineering supported locally in Australia.
Important Electrical Note: Due to the high magnetic efficiency of large toroidal cores, transformers draw an initial magnetization inrush current. Connection to a standard 6kA C-curve switchboard circuit breaker/RCD is recommended for optimal operation.

Frequently Asked Questions (STIS-2400)
Q: Can I plug the PAC 2400W transformer into a standard Australian 10A power point?
A: Yes. At 2400W continuous output on 240V mains, the primary draw is exactly 10 Amps (2400W ÷ 240V = 10A). This makes the STIS-2400 the highest capacity isolation transformer suitable for standard Australian domestic power outlets. For optimal performance with high inrush loads, connection to a C-curve circuit breaker is recommended.
Q: What is the benefit of an isolation transformer over an autotransformer?
A: An autotransformer shares a common neutral wire between input and output. An isolation transformer uses physically separated, double-insulated primary and secondary windings (galvanic isolation). This breaks ground loops, blocks electrical noise, removes 50Hz audio hum, and protects sensitive equipment from mains spikes.
Q: Can I run Japanese 100V and US 120V appliances at the same time?
A: Yes. The STIS-2400 features dedicated 1 x 100V and 1 x 120V outlets. Both sockets can be used simultaneously, provided the combined wattage of connected devices does not exceed 2400 Watts continuous.
Q: What warranty and local support are provided?
A: The STIS-2400 is backed by PAC's 2-Year Australian Replacement Warranty and complies with ACMA and EESS electrical safety standards.
