The universal drive for high-power applications
SINAMICS G150 variable speed enclosed drives
Siemens SINAMICS G150 is an enclosed, air cooled or water cooled (optional), variable speed drive ideal for applications that do not require regeneration back into the power supply system. This very compact, quiet drive includes an AC/AC power module with state-of-the-art IGBT power semiconductors and an innovative cooling concept that provides low-loss operation for extremely high energy efficiency. All units include a controller (CU320) with PROFIBUS port, an advanced operator panel (AOP30), and a terminal module (TM31) for digital and analog inputs and outputs. Standard interfaces guarantee quick integration into the plant and process control scheme, and enable easy start-up and operation.
SINAMICS G150 is available in several versions covering a broad range of voltages and power ratings, with a wide variety of standard options that allow it to meet industry and site-specific needs. It’s ideal for applications that involve moving, conveying, pumping or compressing solids, liquids or gases. In particular this includes variable torque applications such as pumps, fans, blowers, and compressors, as well as constant torque applications such as mixers, extruders, and mills.

SINAMICS G150
SINAMICS G150 enclosed drives are ideal for applications that involve moving, conveying, pumping or compressing solids, liquids or gases. In particular, this includes variable torque applications such as pumps, fans, blowers, and compressors, as well as constant torque applications such as mixers, extruders and mills. The control can be operated in sensorless vector or v/hz modes. Closed-loop vector control can be implemented as well with the addition of the optional encoder interface board. The optional user-friendly AOP30 operator panel with graphical LCD and plain-text display provides easy commissioning and parameterization using interactive menus and alarm and fault logs.
SINAMICS G150 to NEMA standards
The NEMA versions are designed to meet the standards and codes applicable in North America. Since it bears the CE mark, it is also suitable for export to other regions.
Key features for all SINAMICS G150 versions
Standard NEMA 1 enclosure, optional NEMA 1 filtered, or NEMA 12 ventilated
Circuit breaker disconnect per NEC/UL for motor branch circuit protection (type A only)
SCCR per UL508A: details in tab sections below
EMC filter Category C3 for 2nd environment (industrial) per IEC 61800-3
CE mark
The SINAMICS G150 NEMA type A enclosed drive is ready to connect and run
It includes a broad range of standard and optional components, such as a circuit breaker disconnect, input line reactor, various contactors, and a range of control and auxiliary equipment.
Standard features
SCCR per UL508A: 65kA for 480V, 25kA to 35kA for 600V units
Optional UL listing, per UL508A
Input circuit breaker disconnect with rotary operator interlocked with the enclosure door
Optional mechanical door interlocking for additional doors
Semiconductor fuses for SCCR
Input line reactor
AOP30 advanced operator panel (multi language including English, Spanish, French and others)
CU320 controller with PROFIBUS port, TM31 I/O module
Cable entry: line side top and bottom, motor side bottom only, optional top entry
SINAMICS G150 type C is a very compact, basic enclosed chassis, or “drive in a box”
It includes the drive power and control electronics. Most line side and motor side components need to be provided externally, such as in a motor control center (MCC).
Standard features
SCCR per UL508A: 65kA for 480V, 25kA to 35kA for 600V units. Note that the disconnect and short circuit protection must be provided externally, for example in an MCC
Optional UL listing per UL508A
AOP30 advanced operator panel (multi language including English, Spanish, French and others)
CU320 controller with PROFIBUS port, TM31 I/O module
Cable entry: line and motor side bottom only
Optional Input line reactor
SINAMICS G150 cabinet units in a liquid-cooled version
In order to address applications that place increased demands on the cooling of the drive cabinet units due to ambient conditions at the installation site, Siemens offers a custom version of the SINAMICS G150 that offers a NEMA 12 enclosure with closed internal air circulation, and integrated air/liquid heat exchange.
The heat generated by the power loss is dissipated by the cooling water and therefore does not enter the switchgear room or production area. As a consequence, additional climate control for the room or area is not required.
Advantages
- Water circuit remains separate from the electrical drive components
- No need to provide an additional external water-water heat exchanger
- Cabinet is an enclosed unit and complies with IP54 degree of protection - no oil-containing air or dust can enter the cabinet
- Power supply and control for the circulating fans are integrated in the cabinet
- Only the cooling water circuit has to be connected, using commercially available connecting elements
- No special demands are placed on the water quality - for instance, the drive cooling circuit can be combined with an existing motor cooling circuit
- The water connections of several SINAMICS G150 units can be simply connected in series and the cabinets lined-up next to one another
SINAMICS G150 to IEC standards
The IEC version is offered in North America for customers who intend to export to other parts of the world, or where IEC standards are acceptable (for example in the marine industry). The IEC version is not suitable for installation in North America, as it may require additional equipment to comply with NEC / CEC requirements.
Key features
IP20 enclosure, optional IP23, IP46, IP54
Optional fused disconnect switch (version A only)
Optional marine version per a range of certification authorities for non-essential services or with - certification for essential services
