Ratings and Specifications
Amplifier Units
✽1. When there are 8 or more E3X-NA Amplifiers mounted side-by-side, the response time will be 350 μs max.
✽2. Mutual interference prevention is effective when E3X-SD/-NA-series Amplifiers are gang-mounted without other E3X-series Amplifiers.
✽3. Water-resistant models and models with connectors have a dielectric strength of 500 VAC.
✽4. Add 10 g for water-resistant models.
