Product Introduction

The HF series circuit is designed as H type. Power amplifier using power tube metal packaging, and power is a large power transformer installation. It has many functions, such as signal overload, intelligent automatic pressure limit, overload automatic attenuation (such as output power, output short circuit) power supply automatic attenuation, when the temperature exceeds the power amplifier output channel (default 120 C), or automatically cut off the output signal as the cooling condition of low shear and high shear failure.
