3-Phase Servo Linear Stabilizer – 300 kVA

is a high-capacity 300 kVA three-phase servo linear voltage stabilizer from the TPL Series 20%, designed for demanding industrial and commercial applications requiring stable and precise power. It accepts a 3*400Vac+Neutral input and provides a regulated output with an adjustable accuracy of 0.5-1% even with input voltage fluctuations of ±20%. This unit is equipped with extensive protection features, including over/under voltage, overload, short circuit, over heat, internal bypass, input circuit breaker, SafeStart, phase sequence, phase failure, and a ventilation system. A user-friendly touch screen allows for monitoring of parameters such as V, I, PF, and T, and offers manual interference and fault record capabilities. Communication is supported via Ethernet, USP, MODBUS TCP, and GPRS. With a high efficiency of >98% at full load, a 2-year warranty, and 25-year spare part availability, this robust stabilizer ensures reliable long-term performance for large-scale operations. Optional enhancements include input/output surge arrestors, EMI/RFI filter, and a fire sensor. 🔧 Specifications:
