The AMAT 0190 - 91259 is a magnet driver. It is used to perfectly replace the magnet driver with the part code A/M P/N 0190 - 70060 in the original system of AMAT etching machines. The input signal interface, power terminal, drive output terminal, mounting holes, and overall dimensions are exactly the same as the original model, allowing for direct replacement.

It can be directly used in Applied Materials P5000, P5200, ENDURA, and CENTURA machines.

Based on the design of the new - generation intelligent IPM power device, it completely abandons the backward design of using the Darlington transistor power module as the main drive circuit in the original machine. The IPM is a new - generation high - speed power switch device with a high operating frequency and significantly reduced power consumption. It has built - in high - speed over - current, over - heat, and short - circuit protection functions, and the drive protection output circuit is highly integrated, greatly improving reliability.

A drift adjustment circuit is newly added, ensuring extremely small drift currents in each of the two channels under static no - given conditions and also improving the consistency between the two channels. This function is not present in the original machine design, which may lead to the inability to improve the uniformity index and a tendency to deteriorate when the user applies this driver to some machines with high requirements for etching uniformity.

A deviation protection and alarm circuit is innovatively added. This circuit real - time monitors and compares the deviation between the input given current and the actual output current. If the deviation exceeds the specified range, it will trigger an alarm and stop the output. This function effectively eradicates the stubborn problem of the original driver's out - of - control continuous output until the magnet coil is burned out in a faulty state. At the same time, it ensures the linear correspondence between the input and output, preventing the occurrence of偏大or偏小output现象.

The input voltage range is AC180 - 240V for adaptive wide - voltage range input. The input - output correspondence is that an input voltage of ±10V corresponds to an output drive current of ±25A. The control voltage input interface is an 8 - PIN pin - type terminal, the same as the original model. The power input and drive output terminals are Marathon 8 - hole plug - in terminal blocks for P5000 models (model suffix: A) and TE 8 - channel flat screw - type terminal blocks for CENTURA models (model suffix: B). Both types of terminals are the same as the original model.

The protection modes include IPM unit over - heat, DC bus average over - current, output - stage short - circuit, DC bus over - voltage, and excessive deviation of output current from the given current.

It has a full - steel housing with a black plastic spray. The working temperature and humidity are - 10℃ - 60℃, and the ambient humidity is ≤80%. The product weight (excluding the mounting bracket) is 5.6 kg, and the overall dimensions are 235X190X172 (MM). The installation method is through the fixing holes on the base.
