3-Phase Servo Linear Stabilizer – 500 kVA

the pinnacle of three-phase servo linear voltage stabilization, offering a substantial 500 kVA capacity from the TPL Series 20%. Designed for the most demanding industrial and utility-scale applications, it accepts a 3*400Vac+Neutral input and delivers an exceptionally stable output with an adjustable accuracy of 0.5-1%, even amidst significant input voltage variations of ±20%. 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. Premium optional features include high-grade input/output surge arrestors, enhanced EMI/RFI filtering, and an integrated fire detection and suppression system. 🔧 Specifications:
