DC to 10MHz, High Speed and Broad Range Maximum 300Vp-p high output voltage plus, minus, source and sink operation are available

HSA series is a power amplifier which has high speed, broad band (DC to max.10MHz) , and the capability of supplying high voltage and high power. DC+ / DC- signal is variable continuously with wide output range of maximum 300Vp-p without switching. Furthermore, as Four-quadrant output is possible, source mode(providing a power to load from a power amplifier in coincidence of voltage polarity and current polarity as normal amplifier) and sink mode (Sinking a power from load to power amplifier in reverse current) operation are available. Therefore, It is possible to drive smoothly a capacitive load and an inductive load like a piezo electric component, a solenoid and others.

6 difference models concerning frequency range, output voltage and output current are available as HSA series.

Applications

Example of a driving for piezo-electric devices which is used for piezo inverter, piezo actuator and etc. As HSA series have a very low output impedance, good step response is obtained against large capacitance of piezo-electric devices.

Example of magnetized devices for B-H curve measuring of high frequency magnetic materials As HSA series have a flat and a wide frequency response and a high stability against inductive loads, high repeatability data is obtained with no influence of loads.

Example of a withstand ripple test for electric capacitors using a switching power supply. HSA series has not only bias function but also a stable operation against large capacitor loads. It is not caused a difference between a maximum charge current and a maximum discharge current for stable operation against large capacitor loads and symmetry of operation area.

Example of vibration test for flat display panels of FED, EL, LCD and etc.. This test is required a high voltage and a high speed rise time for capacitive load. Wide output voltage range and a high slew rate of 5000V/µs of HSA series is useful for this application.

HSA series is suitable for a power amplifier of signal generators. It is possible to provide a stable power against inductive and capacitive loads with wide frequency range , high output voltage and low output impedance.
