Thông tin sản phẩm

For Brush-Commutated PMDC Motors. Up to 75 W.
This linear four-quadrant PMDC DC servo amplifier is fully enclosed in a rugged aluminum case which can be panel mounted for easy integration. The drive is available in several configurations depending on your control requirements. The drive handles continuous currents up to 3 Amps and is protected against over-current, over-temperature and motor short-circuit.
