Description：

The PN072132P902 3D658187G901 board relies on a clean, low-voltage internal DC bus supply ranging from +15V DC to +24V DC, which is stepped down and isolated internally from the VFD's primary switched-mode power supply (SMPS). It features heavy-duty on-board voltage regulators and filtering capacitors to suppress ripples from high-frequency switching.

The PN072132P902 3D658187G901 board is equipped with multiple precision analog input channels supporting standard 4-20mA / 0-20mA current loops and 0-10V DC differential voltage signals, optimizing dynamic speed references.

Frequently asked questions

What exactly is the PN072132P902 3D658187G901?

It is an internal drive control/main power printed circuit board (PCB) manufactured by Telemecanique (Schneider Electric) for large industrial variable frequency drives (VFDs).

Which VFD series use this specific board?

It is primarily used in high-power Schneider Altivar series, specifically the Altivar 61 (ATV61) and Altivar 71 (ATV71) heavy-duty drives.

What is the typical motor power range this board controls?

It is designed for large industrial chassis, typically controlling heavy-duty motors rated at 160 kW (215 HP) and above.

What is the input voltage requirement for the PN072132P902 3D658187G901 board itself?

The board operates on internal low-voltage DC power (+15V to +24V DC) supplied by the VFD's primary power supply board.

Product Applications
