Features

Stable output under various load conditions

Four-quadrant operation

The operation range of the HSA42011 is four quadrants as shown in the figure below. Current sources and sinks regardless of positive or negative output voltage.

Stable output with both capacitive and inductive loads

When an AC voltage is applied to a load including capacitors and coils, current returns from the load. In this case, a typical AC power supply or amplifier may not be able to drive the load.
The HSA42011 operates in the sink state in which the directions of voltage and current are opposite due to the 4-quadrant output function. Therefore, not only a capacitive load such as a piezoelectric element but also an inductive load such as a solenoid can both be driven stably.

Fast response, wide frequency bandwidth from DC to 1MHz

High speed and high slew rate reproduce transient and repetitive operations with good step response. HSA42011 outputs AC and DC. Therefore, it is possible to output positive/negative asymmetric signals or signals in which AC is superimposed on DC.

Low output impedance

Due to the output impedance of the power supply, the rise time of a capacitive or inductive load is delayed. The HSA42011 maintains a low output impedance over the entire frequency band, suppresses voltage drop due to load, and operates at high speed.

Convenient functions for various purposes

Gain setting

Set seamlessly by combining selectable fixed gain ×1,×10,×20,×50　and variable gain x1 to x3 ( fine adjustment potentiometer)
With a gain ×1 setting, it is used as a buffer amplifier that outputs at the same voltage as the external signal generator setting.

Output polarity switching

With the [INVT] switch on front panel, an amplification can be selected which the input and output phases are in the same or opposite polarity.
BTL connection by two HSA42011 with output polarity set to opposite, the output voltage and power are doubled.
∗BTL : Balanced Transformer Less

Output DC offset voltage adjustment

Adjust the output DC offset voltage to zero volts.

Output DC bias voltage setting

Superimpose a DC bias voltage (up to ±75V) on the output voltage.（Setting by 10-turn potentiometer）

Protection function

Function to protect the load and HSA42011 from abnormal conditions. Overload, overvoltage, internal power supply error, internal temperature error, cooling fan error. When an error is detected, the output is turned off or the overload protection function is activated and the overload LED or error LED lights up. If the abnormal condition continues,all operations except power off are disabled.
