The "HF-A" series power amplifiers are wideband, full
complimentary class AB linear amplifiers with output
impedance of zero ohm. This feature enables our power amplifiers
to have the ability to cope with a wide range of dynamic loads.
The frequency response of our power amplifiers cover the whole
audio frequency (AF) range (20Hz to 20KHz) and part of the radio
frequency (RF) range (up to 800KHz, 1.2MHz in some of the
models). The standard output voltage of the power amplifiers
(without output transformers) is 0-28V rms. With external output
transformers, the output voltage can go up to any level
specified by customers (maximum of 10KV rms.). The output power
rating of our power amplifiers ranges between 50 watts to 1400
watts as an individual unit. Higher power or multiple-phase
configurations can be achieved by combining multiple units. Our
power ratings are for continuous duty at full power with +0.7 to
-0.7 power factor.
Typical customer usage for the amplifiers include plasma
excitation, induction heating, EMC testing, EMI testing,
magnetic field generation, and product testing (such as
Helmholtz coils, piezo elements, inductors, capacitors, etc.).
