Power Amplifier for Helmholtz Coils
Product Overview
PA1 supplies the necessary current to the Helmholtz coil assemblies to generate the required magnetic field. It also applies a DC offset current to the coils, typically used to cancel the ambient magnetic field.
Additional electronic adjustment of the scaling and orthogonality enables the generation of high precision magnetic field with excellent orthogonality accuracy.
PA1 runs from a standard mains AC supply. The amplifier is fan-cooled with a self-resetting thermal shut-down mechanism to prevent damage through overheating.
