Condition: new, For sale: Professional power controller (thyristor-based) Advanced Energy Thyro-A series. The device is NEW – never used (warehouse stock). High-end industrial equipment designed for advanced production installations. 🔧 Technical specifications: Manufacturer: Advanced Energy Model: Thyro-A 3A 400-350 HF RL3 Voltage: 400 V Current: 350 A Output: Relay Out 4A / 250V Type: thyristor power controller (SCR) ⚙️ Applications: industrial furnaces heating systems industrial automation power control in production lines 📦 Included in the set: 3x Thyro-A modules industrial enclosure / heat sink cooling fan full set as shown in photos ✅ Condition: NEW – unused May show minimal signs of storage. Ppodpfx Aoyw T Ipokfjr Fully functional.

Condition: repair required (used), Year of construction: 2009, functionality: limited functionality, machine/vehicle number: 305484, saw blade diameter: 450 mm, cutting height (max.): 160 mm, feed length X-axis: 2,000 mm, cutting range round steel at 45°: 150 mm, cutting range round steel at 90°: 150 mm, type of input current: three-phase, cutting range square steel at 45°: 140 mm, cutting range square steel at 90°: 140 mm, CNC cold saw from the renowned brand Kaltenbach, model KKS 401 NA 2000. There is a lot of technical data to list, so I have uploaded several photos with the basic specifications for you to get an overview of the saw’s capabilities. This is a rare model equipped with a feeder (individual lengths) from 0-2000mm, and for repeat operations from 2000-9999mm. Automatic zeroing before cutting. The CNC saw head features automatic rotation of +/-60 degrees, two types of lubrication (emulsion and direct spray application). You can select between ejection of cut pieces via a small parts ejector or by a chain ejector with a drop-down function for longer and heavier sections. The safety fence assembly with IC barriers and numerous spare parts are included with the saw (not shown in the pictures as it is not currently mounted). All original documentation is provided and corresponds to the machine's serial number, ensuring straightforward installation without guesswork. Ppjdpfeyk Inpox Akfsr Explanation of the issue: the saw is connected to electrical power and every individual function (of which there are many) works perfectly. The problem occurs during automatic operation, most likely due to program parameter issues (it uses the Windows platform). I have not found a suitable programmer willing to learn on my machine. Possible solution: I have contacted the saw manufacturer and they referred me to their authorized service provider, whose contact details I can supply to the prospective buyer. Estimated repair costs in Serbia range from €3000 to €5000; if you are closer to Germany or the Czech Republic, the expenses are significantly lower. Therefore, there are two price categories: if you purchase the machine as is, the listed price applies; if I resolve the issue, the price will be considerably higher. The listed price includes professional dismantling and loading onto the truck (a significant cost factor that is far from negligible); transportation is at the buyer’s expense. I hope this clarifies the current condition of the machine to some extent. Wishing you a successful purchase.
