Siemens SINAMICS V20, G120, and G110 series inverters are premium-to-mid-tier German-OEM variable frequency drives stocked by Flextech Industrial Supplies – and represent approximately 90% of Flextech’s current automation component inventory, providing the shortest quote-to-delivery lead time among all OEM VFD brands stocked in Puchong, Selangor.
Siemens SINAMICS inverters occupy the premium-to-mid tier in the Malaysian VFD market – above Mitsubishi FREQROL on ecosystem integration depth with Siemens S7 PLCs and TIA Portal engineering software, and significantly above value-tier brands on safety function capability (PROFISAFE STO, SS1, SS2), modular hardware architecture, and Malaysian industrial service support from Siemens Malaysia (Shah Alam). Flextech’s stock depth on Siemens products enables same-day dispatch of standard SINAMICS V20 and G120 Power Module frame sizes across Klang Valley.
Siemens Sinamics V20 Variable Frequency Drive for Industry
About Siemens SINAMICS: German-OEM Modular Drive Platform
Siemens SINAMICS series (covering SINAMICS V, G, and S families since 2003 following SIMOVERT MASTERDRIVES predecessor) is a German-OEM VFD platform with modular architecture that separates control intelligence (Control Unit) from power conversion hardware (Power Module) in G and S-series drives - enabling field upgrade of communication protocols, safety functions, and firmware without hardware replacement.
SINAMICS V20 and G120 are the primary Flextech-stocked series for Malaysian industrial applications. V20 targets standalone single-drive applications with fixed hardware, while G120 targets networked multi-drive panel installations with Siemens PLC ecosystem integration. Both series are established in Peninsular Malaysia's F&B processing, building HVAC, water treatment, and automotive manufacturing sectors.
Siemens SINAMICS Product Lines
| Series | Power Range | Architecture | Communication | Key Feature |
| SINAMICS G110 | 0.12-3 kW | Fixed | USS, Modbus RTU | Basic single-phase, lowest cost |
| SINAMICS V20 | 0.12-30 kW | Fixed | USS, Modbus RTU | Compact general-purpose |
| SINAMICS G120 | 0.37-250 kW | Modular (CU + PM) | PROFIBUS, Profinet, PROFISAFE | Network integration, safety |
Siemens SINAMICS G110 covers 0.12-3 kW on single-phase 230 VAC input - the basic compact inverter for small single-phase motor applications in Malaysian commercial HVAC, fan drives, and light conveyor systems where cost minimisation is the primary criterion. G110 provides V/f control only (no vector), USS protocol communication, and manual BOP-2 operator panel for standalone operation.
Siemens SINAMICS V20 covers 0.12-30 kW - the compact fixed-hardware SINAMICS inverter and Flextech's primary stock item for general-purpose Malaysian industrial motor speed control. V20 provides V/f and sensorless vector control, USS and Modbus RTU RS-485 communication, built-in PID controller, and an industry-documented "QuickComm" parameter setup procedure (6 parameters for basic configuration). SINAMICS V20 is interoperable with non-Siemens PLCs via Modbus RTU - it does not require a Siemens S7 PLC to function as a networked drive.
Siemens SINAMICS G120 covers 0.37-250 kW with modular Control Unit + Power Module architecture. The CU240E-2 control unit provides PROFIBUS-DP and Modbus RTU. The CU250S-2 adds encoder input for closed-loop vector (V/f, sensorless, and closed-loop). The CU240E-2 PN provides PROFINET with PROFISAFE safety functions. This modularity means a Malaysian plant commissioning 30 G120 drives can standardise on one CU type and vary only the Power Module for different motor power ratings - reducing commissioning time and spare parts inventory complexity.
Technical Specifications
Input voltage: Three-phase 400-480 VAC (covers Malaysian TNB 415 VAC three-phase within ±10% tolerance) for V20 and G120 three-phase models. Single-phase 230 VAC for G110 and V20 small-frame models (0.12-1.5 kW).
Overload capacity: 150% for 60 seconds, 200% for 3 seconds across V20 and G120 series - standard inverter acceleration overload for direct-online motor starting profiles. G120 at high duty cycle provides derating tables for elevated ambient (Malaysian 35°C factory floor applications require thermal calculation for G120 above 45 kW).
PROFISAFE safety functions (G120): STO (Safe Torque Off), SS1 (Safe Stop 1), SS2 (Safe Stop 2), SOS (Safe Operating Stop), SLS (Safely-Limited Speed) - IEC 62061 SIL2 and ISO 13849 PLd rated. Malaysian machine builders supplying EU-market machines requiring machinery directive conformity specify G120 with PROFISAFE for pressing machine guard-interlock drives and palletiser safety zones.
TIA Portal integration: SINAMICS G120 with Profinet CU240E-2 PN integrates with Siemens S7-1200 and S7-1500 PLCs via SINAMICS Startdrive engineering tool within TIA Portal - enabling drive parameter configuration, motor identification, and safety function commissioning from the same software environment as PLC programming. For Siemens-standardised Malaysian plants, this single-software-environment advantage reduces cross-tool configuration errors.
Siemens SINAMICS for Malaysian Industrial Environments
Siemens SINAMICS V20 and G120 operate to 50°C ambient without derating on standard models - Malaysian factory ambient of 28-35°C provides substantial thermal headroom for continuous rated-current operation. SINAMICS G120 Power Modules are IP20 (panel-mount) as standard; SINAMICS G120X variant adds IP65/IP66 for outdoor and wet-area motor control in Malaysian water treatment pump stations and palm oil mill field installations.
NIMP 2030 (National Industrial Master Plan 2030) energy efficiency targets drive adoption of inverter retrofits on fixed-speed motors across Malaysian manufacturing. SINAMICS V20 with the built-in pump/fan characteristic curve (energy-saving mode) achieves 20-40% motor energy reduction on variable-torque loads - payback periods of 12-24 months are standard in Malaysian industrial pump retrofit applications.
Siemens SINAMICS V20 vs G120: Selection Guide for Malaysian Buyers
Specify SINAMICS V20 when: (1) Standalone single-drive application without Siemens PLC network integration. (2) Budget-optimised general-purpose motor speed control up to 30 kW. (3) Modbus RTU cross-brand PLC communication adequate (non-Siemens PLC application). (4) Fixed hardware acceptable - no modular upgrade requirement.
Specify SINAMICS G120 when: (1) Machine uses Siemens S7-1200 or S7-1500 PLC with Profinet network - G120 with CU240E-2 PN integrates via TIA Portal drive object. (2) Safety function (STO, SS1) required for machinery directive conformity. (3) Power above 30 kW - G120 covers to 250 kW. (4) Modular architecture needed for panel standardisation across varying motor power ratings.
Applications in Malaysian Manufacturing
Building HVAC - SINAMICS V20 on chiller secondary pump drives, cooling tower fan drives, and AHU fan inverters in Malaysian commercial buildings and industrial facilities, where simple PID pressure control on 4-20 mA feedback suffices.
Water treatment - SINAMICS G120 with CC-Link IE or Profinet on booster station pump drives in Malaysian Indah Water and industrial WTP facilities, integrated with Siemens S7-1500 SCADA systems.
Automotive assembly (Shah Alam, Rawang) - SINAMICS G120 with PROFISAFE on press brake and stamping machine drives in Malaysian Tier 1 automotive plants, where SIL2-rated safety stop functions are required for CE-marked machine conformity.
Siemens ecosystem plants - Malaysian manufacturers standardised on Siemens S7-1200 PLCs (the most common mid-range PLC in the Malaysian SME market) specify SINAMICS V20 for Modbus-connected pump/fan drives and G120 for Profinet-integrated multi-drive conveyor and machine axis applications.
Genuine OEM Siemens vs Grey-Market Inverters
Grey-market Siemens SINAMICS inverters - parallel imports lacking Malaysian warranty registration - are present in the Malaysian market. Genuine Siemens SINAMICS inverters from Flextech carry CE marking, Siemens holographic authentication, valid serial number registration for Siemens Malaysia warranty service, and Siemens TIA Portal firmware update eligibility. Grey-market units frequently lack current firmware, missing CE documentation, and no warranty path from Siemens Malaysia.
