Anorad Dual Channel Dual Axis Linear Amplifier from an Anorad SPG gantry.

Description:

These units appear to be in decent functional shape, with some rust and scratches. These units are untested, however they are guaranteed to be functional beyond the stated defects. These units include the pictured add on board that has the chip that says "Divider".

The Dual Channel Linear Amplifier with linear output current drive virtually eliminates electromagnetic interference (EMI) for applications with sensitive sensing electronics or where system materials are sensitive to electromagnetic fields.

This compact, highly integrated package contains the drive for two independent 3-phase brushless motors, associated heat sink with forced air cooling, and a 40 VDC linear bus power supply with an isolated 115 VAC or 230 VAC IEC-320 power input.

The on-board DSP self-teaches the most efficient commutation angle for each drive providing smooth 3-phase sine wave commutation based on quadrature encoder position feedback. All digital interface signals are optically isolated to avoid problems associated with ground referenced control signals. The analog control command (+/-10 VDC) can be a differential input, which rejects normally encountered common mode noise.

An encoder interpolator option is available to accept analog sine/cosine position encoder signals, with 5,10,or 25X multiplication.

Amplifier over-temperature faults, and motor over-power (I²t) faults are provided.
