3-Phase Servo Linear Stabilizer – 500 kVA

three-phase servo linear voltage stabilizer from the TPL Series 30%, designed for demanding industrial and commercial applications requiring stable and precise power even with substantial input voltage variations. 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 incorporates an exhaustive array of protection features, including over/under voltage, overload, short circuit, over heat, internal bypass, input circuit breaker, SafeStart, phase sequence, phase failure, and a high-efficiency ventilation system. A sophisticated touch screen interface provides detailed real-time monitoring of crucial parameters (V, I, PF, T), advanced manual intervention capabilities, and comprehensive fault history management. Seamless communication is ensured through Ethernet, USP, MODBUS TCP, and GPRS integration. With a high efficiency exceeding 98% at full load, backed by a 2-year warranty and long-term spare part support, this robust stabilizer guarantees unwavering and dependable power for critical infrastructure and large industrial complexes in challenging power environments. Premium optional features include high-grade input/output surge arrestors, enhanced EMI/RFI filtering, and an integrated fire detection and suppression system. 🔧 Specifications:
