PAC Toroidal Voltage Converters — Ultra-Quiet Galvanic Isolation for Sensitive Electronics
Deliver pure, isolated AC power to your imported 100V Japanese and 110V–120V North American electronics with the PAC 600W Isolated Toroidal Step-Down Transformer (SKU: STIS-600).
Engineered specifically for noise-sensitive applications like audiophile sound systems, home studio rigs, and vintage electronics, the STIS-600 provides true galvanic isolation between the Australian 240V mains and output sockets. By physically isolating the primary and secondary copper windings, it breaks ground loop circuits, eliminates 50Hz earth hum, and prevents grid-borne line spikes from reaching delicate circuits.
Key Features:
- True Galvanic Isolation: Physically separated primary and secondary windings eliminate ground loops and deliver whisper-quiet audio performance.
- Dead-Silent Toroidal Core: Engineered with a high-efficiency toroidal core to eliminate mechanical buzzing and vibration on audio shelves.
- Dual Output Outlets: Features 1 x 100V (tailored for Japanese audio and gear) and 1 x 120V (North America) for simultaneous or dedicated use.
- 600W Continuous Duty: High-purity copper windings rated for 600 Watts continuous 24/7 duty.
- Dual Layer Electrical Protection: Protected by an accessible panel fuse and internal automatic thermal cutoff.
- Standard Australian Plug: Connects into any standard 10A domestic wall power point with low, smooth current draw.
- 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.

Frequently Asked Questions (STIS-600)
Q: How is the PAC STIS-600 protected against overloads if it does not have a circuit breaker switch?
A: The STIS-600 utilizes an integrated fuse protection system combined with an automatic internal thermal safety cutout. If an accidental overload or short circuit occurs, the fuse blows safely to protect connected equipment, and the thermal sensor shuts down the core before excessive heat buildup can occur.
Q: Why should I buy this isolation transformer over a regular step-down transformer for audio?
A: Standard autotransformers physically connect the neutral line of your audio gear to the Australian mains ground. This creates a ground loop circuit that picks up 50Hz electrical hum, dimmer buzz, and refrigerator clicks. The STIS-600 uses physically isolated coils (galvanic isolation), completely severing that connection and lowering the noise floor to silence.
Q: Can I run Japanese 100V and US 120V equipment at the same time?
A: Yes. The STIS-600 provides separate 1 x 100V and 1 x 120V sockets. Both can run simultaneously as long as the total combined wattage remains under 600 Watts continuous.
Q: What warranty and local support are provided?
A: The STIS-600 is covered by PAC's 2-Year Australian Replacement Warranty and complies with ACMA and EESS electrical safety standards.
