Frequently Asked Questions (FAQs)

Product Usage and Features

1. What are ROCKSTONE POWER Transformers designed for?

ROCKSTONE POWER Transformers, including Step Up/Down Transformers, Voltage Converters, and Dual Voltage Transformers, are versatile devices intended for global use across electronics, heavy-duty machines, and industrial applications.

2. Choosing the Right Transformer for Your Appliance

Safety first! Select a Voltage Converter/Transformer with a maximum wattage at least 50% higher than your appliance's wattage. For example, a 3000 Watt transformer is suitable for an appliance that uses up to 2100 Watts. This ensures safety and prevents damage to both the transformer and the appliance.

3. Understanding the Miniature Circuit Breaker (MCB)

The MCB in ROCKSTONE POWER Transformers offers advanced over-current protection. It's more sensitive and reliable than traditional fuses, automatically shutting off in overload or faulty conditions for easy troubleshooting.

What's Included with Your ROCKSTONE POWER Transformer

Each unit comes with:

  • Voltage Transformer Converter
  • Hardwired Insulated Power Cord (US Grounded 3-Prong Plug)
  • European Grounded Schuko Wall Outlet Plug Adapter
  • 2 Spare Fuses
  • Instruction Manual
