For Sale: Used Siemens 22 KW Variable Frequency Drive (VFD) / Inverter in Excellent Condition - Siemens SED2** Quantity: 2 converters, each 22 KW / 30 HP. Offering for sale a used Variable Frequency Drive (Inverter / VFD) from the renowned German company Siemens. The SED2 model is specifically designed for heavy-duty applications and is ideal for HVAC, pumps, and industrial machinery. **Technical Specifications:** * **Brand:** Siemens - Made in Germany. * **Model:** SED2-22/32X (Part Number: 6SE6436-2UD32-2DA0). * **Compatible Motor Power:** 22 KW / equivalent to 30 HP. * **Input Voltage:** 3-phase (3AC) from 380 to 480 Volts. * **Output Voltage & Frequency:** 45 Amps current, variable frequency from 0 to 150 Hz. * **Weight:** 16 Kilograms. * **Control Panel:** Equipped with an integrated digital control screen supporting manual (Hand) and automatic (Auto) operation with programming buttons (Fn, P). **How this Device Works:** The Inverter (VFD) precisely controls the speed and torque of electric motors (AC Motors). Instead of running the motor at a single fixed speed (on/off), this device changes the frequency and voltage supplied to the motor, allowing it to operate at variable speeds as needed. This means it starts the motor slowly (Soft Start) and then gradually increases the speed, protecting the motor from startup shocks and extending its lifespan. **Key Applications:** 1. **Pumps (Water & Agricultural):** To control water pumping power based on demand, leading to significant electricity savings and preventing pipe bursts due to sudden pressure. 2. **Central HVAC Systems:** Controlling the speed of large fans and cooling compressors based on the required temperature. 3. **Industrial Machinery & Factories:** Operating conveyors, mixers, and filling machines that require precise rotational speed control. 4. **Lifts and Cranes:** Ensuring smooth lifting and lowering movements. **Why Buy This Device?** * **Electricity Savings:** Significantly reduces energy consumption when motors operate below their maximum speed. * **Motor Protection:** Protects motors from high inrush currents and electrical fluctuations. * **Siemens Quality:** Characterized by high reliability and a long lifespan. **Device Condition:** Used and clean, well-maintained. **Asking Price:** [ "On Auction"]
