Newtons4th N4L LPA01 & LPA400 Laboratory Power Amplifiers


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


- Switch selectable coupling options: AC, AC+DC or AC with reduced DC. - 1A continuous output current @ up to กำ12V peak (LPA01).
- DC accurate and wide bandwidth - Switch selectable precision gain settings.
