High-Speed Bipolar Power Supply HSA Series

Capable of handling signals from DC up to 10MHz, a high-speed, wide-bandwidth, high-voltage, high-power-output bipolar power amplifier

The HSA Series is a high-speed, wide-bandwidth, high-voltage-output bipolar power amplifier capable of handling signals from DC up to 10MHz.

Voltage and current can be freely output in four quadrants, both positive and negative, so it can operate in supply mode (just like a general power supply or amplifier, where the directions of voltage and current are the same and power is supplied from the power source to the load) or in absorption mode (where the directions of voltage and current are opposite and the power source absorbs power from the load). Therefore, it can operate stably even with capacitive loads such as piezoelectric elements and coils, or inductive loads.

Six models are available depending on the frequency band, output voltage, and output current.

Operating Range of the HAS Series

	High speed, wideband, high output voltage slew rate Frequency band from DC up to 10MHz, output voltage slew rate up to 5000V/μ s. Even steep-rising high-speed pulse signals or complex waveform signals can be faithfully amplified.
	High voltage output Maximum output voltage is 300 Vp-p. It can comfortably drive piezoelectric actuators, display devices, etc.
	4-quadrant output Regardless of voltage polarity, it can both source and sink power.
	Good step response Maximum output voltage slew rate is 5000 V/μ s. Even for rapid repetition or high-speed transients, it can faithfully reproduce them with good response.
	Two input systems Inputs consist of two systems, A and B. Input switching or addition can be performed with a single button press.
	DC bias Equipped with a DC bias function that can superimpose DC (bias) on the output.
	Low output impedance Good response can be obtained even for capacitive and inductive loads.
	Six models are available according to different frequency bands, output voltages and output currents.
	Other functions Range shift possible (output range can be changed), DC offset adjustment function (adjusts the DC bias contained in the output to zero), protection circuit, monitoring meter, monitor output, output ON/OFF switching, etc.
