3-Phase Servo Linear Stabilizer – 300 kVA

is a high-capacity 300 kVA three-phase servo linear voltage stabilizer from the TPL Series 30%, designed to provide stable and precise power output even under substantial input voltage fluctuations. It accepts a 3*400Vac+Neutral input and delivers a regulated output with an adjustable accuracy of 0.5-1% across an input voltage tolerance of ±30%. This unit is equipped with a full suite of 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. An intelligent 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 in challenging power environments. Optional enhancements include input/output surge arrestors, EMI/RFI filter, and a fire sensor. 🔧 Specifications:
