Features
The TD250 is an ultra-low noise, six-channel +/-250V amplifier suited to driving piezoelectric tubes and other actuators. The six channels can be ordered as either independent (TD250-SGL), or as three channels with non-inverting and inverting outputs (TD250-INV), which is ideal for driving piezoelectric tube scanners. The inverting configuration can also be used to obtain +/-500V with a bridged load.
The TD250 can drive unlimited capacitive loads such as piezoelectric tubes, stack actuators, standard piezoelectric actuators, and bender actuators. Applications include nanopositioning, microscopy, electro-optics, and vibration control. The input and output connectors are industry standard 9-Pin D-Sub connectors. The amplifier is supplied with two 90cm DSUB cables and two breakout boxes that include BNC connectors and plug-in screw-terminals. OEM and customized versions are also available.

Power Bandwidth
The power bandwidth is the maximum frequency periodic signal that can be reproduced without distortion. The calculator determines the maximum operating frequency and required power for a given load capacitance. The calculator includes the effects of current limit, slew-rate, and signal bandwidth. The calculator does not include the time-constant of the peak current limit, and may be inaccurate when the power bandwidth is below 100 Hz.
