The 400V power amplifier is a very practical signal amplifier, which has the advantages of small size, light weight and easy operation, high voltage output (400Vp-p) and large output current (2.8Ap-p).

The maximum value of the continuous output DC current of this machine reaches 0.5 A, the voltage amplification gain is 40 times, the output is adjusted from 0V~400Vp-p infinite (using a large variable resistor of 10 revolutions), and the bandwidth is 30kHz (based on the voltage 400Vp-p output), which is very suitable for semiconductor high-voltage drive, TFT industry drive, microelectromechanical engineering, piezoelectric material drive and audio signal amplification drive.

Specification:

(1)Input:

Specified input voltage: 0 V ~ /- 5 V (10 Vp-p), maximum /- 10V (20 Vp-p)

Specified input frequency: 0~ 30kHz, higher frequency will be attenuated, will not cause damage to the unit, please feel free to use.

Input waveform: DC and any waveform.

(2)Output:

Output voltage: ≦0 V ~ /- 200 V (400 Vp-p), it is strictly forbidden to be directly connected to the oscilloscope for observation, please choose a differential probe with withstand voltage above the peak value of 450V for transfer observation, such as N1015A, N1070A, etc.

Amplification gain: ≦0 ~ 40 times, the panel is marked with AMPL, which is continuously variable composed of a large 10-turn variable resistor.

Maximum output current: ≦2.8Ap-p

Rate of climb: 40V/us

Output bandwidth: 0~30KHz (400Vp-p output)

DC offset: ≦0 ~ /-200 V DC, operated by 10 turn large variable resistor.

DC offset switch: selected by one switch, when the switch is selected as OFF, the internal DC is set to 0V, when the switch is set to ON, it is controlled by the OFFSET knob marked on the panel.

Monitoring output: -40dB, about 1/100 of the voltage level of the output, the output impedance is 10KΩ, and the maximum output is ≦ 4 Vp-p, so it can be directly connected to the oscilloscope to observe the waveform.

(3)Power input: AC 100 V ~ 240 V /- 10%, 50 ~ 60 Hz

(4)POWER CONSUMPTION: 200 WATT MAX

(5)Power dissipation: DC50W, AC100W
