Laboratory Power Amplifiers

LPA01 & LPA400 are the first in a range of amplifiers developed to provide high accuracy amplification in an industrial or laboratory environment.

The LPA range

The LPA range of power amplifiers from Newtons4th Ltd are robust and reliable for use in a variety of industrial and laboratory applications. Designed originally for use with the PSM2200 and PSM2201, they can also be used anywhere where there is a need to boost a signal either in voltage or current.

They combine DC accuracy with wide bandwidth to faithfully reproduce complex waveforms, driving loads that may be capacitive, inductive or resistive.

Optionally, the DC component can be eliminated with ac coupling, or can be reduced with AC+(DC) coupling. To limit high frequency noise, the input bandwidth can be reduced with a linear phase, 2nd order, low pass filter for low frequency applications.

The amplifier gain is selectable from three precision gain settings.

Wide bandwidth precision voltage and current amplifiers

Common Features

LPA01

- Switch selectable coupling options: AC, AC+DC or AC with reduced DC.	- 1A continuous output current @ up to ±12V peak (LPA01).
- DC accurate and wide bandwidth	- Switch selectable precision gain settings.
- Switch selectable bandwidth.	- High slew rate.
- ±400V peak, 50mA rms (LPA400).	- ±180V peak, 100mA rms (LPA400B).
- Isolated from ground to prevent earth loops.	- Will fit underneath PSM2200 or PSM2201 to boost output capability.
- Unconditionally stable into any load.	- Robust metal enclosure

High frequency, high current testing of wound components.

High frequency excitation of servos and actuators up to 1A.

LPA400

High voltage, high frequency calibration.

Driving high voltage actuators (e.g. piezo) up to ±400V.
