Vincotech flowPIM 0 vs flowPIM 1 vs flowPIM 2: Power Module Selection Guide
Vincotech flowPIM modules integrate the main power stages required in a three-phase motor drive. Depending on the selected model, the module can combine a rectifier, brake chopper, inverter and temperature sensor in one package.
The main difference between flowPIM 0, flowPIM 1 and flowPIM 2 is package size and supported power level. flowPIM 0 targets compact, lower-current drives; flowPIM 1 covers medium-power systems; and flowPIM 2 provides a larger thermal platform for higher-current applications.

Vincotech flowPIM 0
flowPIM 0 is the smallest of the three families. Its compact footprint makes it suitable for low-power motor drives and applications with limited PCB space.
Typical 1200V models include:
V23990-P848-A58-PM: 1200V, 4A
V23990-P849-A58-PM: 1200V, 8A
V23990-P840-A58Y: 1200V, 15A, Press-Fit
flowPIM 0 is a suitable choice for pumps, fans, small compressors and embedded motor-control systems.
Vincotech flowPIM 1
flowPIM 1 provides more current capability and thermal capacity than flowPIM 0 while maintaining a relatively compact package. It is commonly used in industrial variable-frequency drives and servo systems.
Representative models include:
V23990-P588-A41-PM: 1200V, 15A
V23990-P589-A418Y-PM: 1200V, 25A, Press-Fit
V23990-P580-A46-PM: 1200V, 35A with AlN isolation
flowPIM 1 offers a practical balance between package size, output current and thermal performance.
Vincotech flowPIM 2
flowPIM 2 uses the largest housing in this comparison. Its copper baseplate provides lower thermal resistance and improved heat spreading, making the family suitable for higher-current motor drives.
Representative models include:
30-P212PMA050M7-L888A79Y: 1200V, 50A, Press-Fit
30-P212PMA100M7-L880A79Y: 1200V, 100A, Press-Fit
V23990-P768-CY: 1200V, 50A converter-and-inverter version
The flow 2 housing measures 107.2 × 47 mm and uses a convex copper baseplate to improve thermal contact.
Which flowPIM Module Should You Choose?
Choose flowPIM 0 when:
PCB space is limited
The application requires relatively low current
A compact integrated motor-drive stage is the priority
Choose flowPIM 1 when:
The system requires a balance of size and power
The application is an industrial VFD, servo or compressor drive
Solder-pin or Press-Fit options are required
Choose flowPIM 2 when:
Higher current capability is required
Thermal performance is a primary consideration
The application uses a larger industrial motor or inverter
FAQ
What does PIM mean in flowPIM?
PIM stands for Power Integrated Module. A typical PIM combines the input rectifier, brake chopper and three-phase inverter.
Are flowPIM 0, 1 and 2 electrically interchangeable?
No. They use different package dimensions, pin layouts and current ratings. The electrical and mechanical specifications must be checked before replacement.
Which series is best for compact motor drives?
flowPIM 0 is generally the best starting point for compact, lower-power motor drives.
Which series supports the highest power?
flowPIM 2 provides the largest housing and thermal platform, making it the preferred option for higher-current applications.
Are Press-Fit versions available?
Yes. Selected flowPIM models are available with Press-Fit pins, while others use solder pins. The exact connection is identified by the full part number.
