ABB vs Siemens vs Allen Bradley VFDs: Which Are Worth More?
When it comes to Variable Frequency Drives (VFDs), the market leaders ABB, Siemens, and Allen Bradley dominate the landscape with high-quality, reliable products. For sellers nationwide looking to maximize the return on surplus VFDs, understanding the nuances between these brands, their models, and market demand is critical. This article, authored by Sean Rupley of Industrial Surplus World with over 30 years of experience in industrial surplus buying, dives deep into the question: ABB vs Siemens vs Allen Bradley VFDs: which are worth more?
Overview of the VFD Market and Brand Positioning
VFDs control the speed and torque of electric motors, optimizing energy usage and improving process control. The three brands—ABB, Siemens, and Allen Bradley (Rockwell Automation)—are global leaders known for their innovation and performance. However, the resale value of their drives varies due to brand perception, technological features, model popularity, and industry adoption.
Before evaluating value, here’s a brief brand positioning overview:
- ABB: Known for rugged, energy-efficient drives with a strong focus on industrial automation and power quality. Widely used in heavy industries like mining, oil & gas, and manufacturing.
- Siemens: Offers a broad portfolio of VFDs across low to medium voltage ranges, integrating seamlessly with Siemens automation systems. Preferred in automotive, food processing, and infrastructure sectors.
- Allen Bradley: A Rockwell Automation brand, Allen Bradley VFDs are prized for user-friendly programming, integration with Allen Bradley PLCs, and solid performance in manufacturing and process control industries.
Technical Specifications and Popular Models
When assessing value, sellers should know which models and specs are most sought after by buyers. Here’s a breakdown of common models and their specifications:
| Brand | Popular Model | Power Range | Voltage | Key Features |
|---|---|---|---|---|
| ABB | ACS580 | 0.75 kW to 500 kW | 230V / 400V | Built-in energy optimizer, integrated safety options, and robust design |
| Siemens | Sinamics G120 | 0.37 kW to 630 kW | 230V / 400V | Modular design, scalable performance, integrated safety features |
| Allen Bradley | PowerFlex 525 | 0.75 kW to 250 kW | 230V / 460V | Integrated Ethernet/IP, easy setup, compatible with Studio 5000 |
Industrial Grading and Model Age
Resale value depends heavily on model age and condition. Drives less than 5 years old with original firmware and intact factory seals command top dollar. Industry-standard grades like NEMA 1 (indoor use) or NEMA 12 (dust-tight) also impact value. For example, a NEMA 12 Siemens Sinamics G120 in excellent condition will fetch a higher price than a 10-year-old ABB ACS550 drive.
Which Brand Commands the Highest Resale Value?
Based on decades of buying and selling experience, here is how the brands rank in typical resale value:
- Siemens: Siemens VFDs, especially the Sinamics series, tend to command the highest resale prices. Their modular design and compatibility with extensive automation systems make them highly desirable. A used Siemens Sinamics G120 15 kW drive in excellent condition can sell for 60-70% of the new price, often around $1,200-$1,500 depending on configuration.
- Allen Bradley: Allen Bradley drives, notably the PowerFlex 525 and 755 series, retain significant value due to their ease of integration with Rockwell PLCs and widespread adoption in North America. Sellers can expect around 50-65% of original price for units under 5 years old and in good condition. For instance, a PowerFlex 525 10 HP drive could resell for approximately $900-$1,100.
- ABB: ABB drives generally sell at slightly lower prices relative to Siemens and Allen Bradley. While robust and reliable, global demand for ABB VFDs in the used market is somewhat less concentrated in North America. The ACS580 7.5 kW (10 HP) used drive typically sells for about 45-60% of new price, approximately $700-$900.
Factors Affecting Value Beyond Brand
Several other factors influence resale worth, regardless of brand:
- Drive Size and Power Rating: Medium power drives (5-15 kW) generally have the highest demand due to their versatility in various industries.
- Communication Protocols: Drives with built-in Ethernet/IP, Profinet, or Modbus TCP/IP interfaces are more valuable.
- Firmware and Software Compatibility: Drives updated with the latest firmware and compatible with current programming software sell better.
- Physical Condition and Completeness: Drives with original manuals, programming cables, and in undamaged condition command higher prices.
- Market Demand and Industry Trends: Demand fluctuates with industrial growth sectors like renewable energy, packaging, and automotive manufacturing.
Practical Advice for Sellers of ABB, Siemens, and Allen Bradley VFDs
Maximizing your return as a seller involves several practical steps:
1. Identify and Document Precise Drive Information
Always record the model number, power rating, voltage, and serial number. For example, a Siemens Sinamics G120 CU240-2 15 kW / 400V drive is more marketable than a generic description. Providing datasheets or manuals increases buyer confidence.
2. Clean and Test Drives Before Sale
Functional drives tested according to manufacturer specs command higher prices. If possible, run a test cycle and confirm basic parameters like output voltage and frequency modulation. Clean exterior with no corrosion or damage is essential.
3. Highlight Communication Features
Drives with Ethernet/IP (Allen Bradley), Profinet (Siemens), or ABB’s own fieldbus options should be emphasized in listings.
4. Consider Current Market Demand
For instance, Allen Bradley VFDs see higher demand in North America due to the prevalence of Rockwell Automation controls. Siemens drives are favored in Europe and Asia but also maintain strong North American markets. ABB is growing in the renewable energy and mining sectors.
5. Package Drives with Accessories When Possible
Offering drives with associated cables, filters, or manuals can increase perceived value significantly.
Industry Insights: Market Pricing Trends
According to recent auction data and surplus market analysis, the following average resale price ranges apply for 10 kW VFDs in good condition:
- Siemens Sinamics G120: $1,000 - $1,500
- Allen Bradley PowerFlex 525: $900 - $1,200
- ABB ACS580: $700 - $1,000
For larger drives (50 kW+), prices scale accordingly but percentage resale value usually decreases slightly due to less frequent demand for high-power units.
Note: Prices fluctuate with the availability of newer models and technological advances such as integrated safety features and harmonic mitigation.
