Upgraded Analogue Amplifiers Series
SQV
for output voltages
+ 150 V
+ 500 V
+ 1000 V
Single/triple-channel devices increased output currents for
better dynamics low noise for high positioning stability reasonable pricing.
| General The amplifier series SQV
150 and SQV 500 have been completely revised to improve output power (current) and noise.
The relevant data in the former main catalogue are therefore obsolete. Additionally, the
SQV 1000 series has been introduced to supply voltages up to +1000 V. Like the former
devices, the SQV amplifiers show a manual setting of a DC-output voltage level (Offset),
which is superimposed to the amplified external signal.
The SQV type amplifiers are the base program to drive piezoelectric and
electrostrictive actuators. By the increase of the output current, now a dynamic operation
of actuators is possible, especially when some power matching is done between actuator and
amplifier by combining high voltage actuators with lower voltage supplies (see main
catalogue section "power matching"/ p. 5).
Only when further increased dynamics are needed, the higher power
amplifiers series NW and LE are recommended. |

SQV 3/150 amplifier shows three independent channels for driving 3 separate piezoelectric
actuators, eg. for piezoactuated xyz adjusters in optics.
The data of each individual channel equals to the above described
single channel device SQV 1/150 with respect to electrical performance and controls.
Additionally, a dial is provided to select the channels for displaying
on the LCD.
