PAC Toroidal Voltage Converters — High-Capacity 2400W Galvanic Isolation for Audiophile & Commercial Equipment
Safely run your heavy-draw imported 100V Japanese and 110V–120V North American audio, culinary, and technical equipment in Australia with the PAC 2400W Isolated Toroidal Step-Down Transformer (SKU: STIS-2400).
Unlike standard autotransformers that share common ground and neutral pathways with noisy household wiring, the STIS-2400 features true physical galvanic isolation. By utilizing completely separated primary and secondary copper windings, it severs electrical noise paths, eradicating ground loop hum, buzz, and radio frequency interference caused by air conditioners, refrigerators, and dimmer switches.
Engineered around a massive, premium-grade toroidal core, the STIS-2400 operates with silent acoustic efficiency and minimal magnetic stray fields. Designed to operate right up to the 2400W limit of a standard Australian domestic 10A circuit, it effortlessly handles high-power multi-channel audio amplifiers, recording studio consoles, sensitive test instrumentation, and high-wattage imported espresso machines.
Key Features:
- True Galvanic Isolation: Physically isolated dual windings sever ground loop pathways to produce an ultra-silent audio noise floor and safeguard delicate electronics.
- Dead-Silent Toroidal Core: Premium wound core design ensures cool operation with virtually zero acoustic chassis vibration or 50Hz hum.
- Maximum 10A Domestic Output: Delivers up to 2400 Watts continuous 24/7 duty without requiring expensive 15A wall socket retrofits.
- Dual Multi-Voltage Outlets: Independent front-panel outlets for 1 x 100V (Japan) and 1 x 120V (USA/Canada) for single or simultaneous operation up to 2400W total.
- High-Retention Pressed Metal Sockets: Industrial-grade contact sleeves provide firm, arcless connections for 2-pin, 2-pin polarized, and 3-pin grounded plugs.
- Front-Panel MCB Protection: Resettable miniature circuit breaker trips safely during overcurrent situations and resets with a single push—no replacement fuses needed.
- Australian Standards Compliant: ACMA and EESS Responsible Supplier registered for Australian electrical safety.
- 2-Year Replacement Warranty: PAC commercial-grade engineering supported directly from South Australia.

Frequently Asked Questions (STIS-2400)
Q: Can the STIS-2400 plug into a standard Australian domestic wall socket?
A: Yes. The STIS-2400 is fitted with a standard Australian 10A 3-pin plug. Because 2400W is the maximum rated continuous capacity of an Australian 10A circuit (240V x 10A = 2400W), it provides the maximum possible isolated power available without requiring a dedicated 15A wall point.
Q: What is the benefit of galvanic isolation over a standard autotransformer?
A: Autotransformers connect input and output coils along a shared neutral wire, allowing mains electrical noise, ground loops, and harmonic hash to enter connected gear. The STIS-2400 uses completely separated primary and secondary windings (physical galvanic isolation) to block DC paths, sever ground loops, and eliminate audible 50Hz hum.
Q: Can I use both the 100V and 120V outlets simultaneously?
A: Yes. You can power Japanese (100V) and North American (120V) equipment simultaneously as long as their combined continuous wattage does not exceed 2400 Watts.
Q: How does the circuit breaker function during an overload?
A: The STIS-2400 is equipped with a front-panel resettable miniature circuit breaker (MCB). If an electrical overload occurs, it trips automatically to protect your equipment. Once the fault is cleared, push the breaker to reset—no fuses required.
