Product Overview

• Part No: SNAT634PAC
• Brand: ABB

• Category: Pulse Amplifier Drive BoardSNAT634PAC is a professional pulse amplification drive board applied in ABB medium voltage power conversion systems. It receives weak control pulse signals transmitted from the main control unit, amplifies and shapes signals into stable drive pulses to trigger high-power semiconductor devices. The board monitors operating status of power components in real time and feeds back fault signals to the main controller. It acts as a key signal transmission bridge between low-voltage control circuits and high-power power units to guarantee reliable switching action of power devices.
