On-Line UPS 277V-480V-3-Phase in-3-Phase out-10KVA -60KVA
Features
- Advanced technology of PWM, DSP and IGBT switching components Designed to use a high frequency, highly efficiency DSP/IGBT and PWM technology in converting DC to AC power.
- True Galvanic isolation design Solve ultimately the problem of power system, including noise, lightning, and leakage current etc.
- Multi-CPU design and software/hardware cooperate control Make the system extremely high reliable.
- Plug & Play modular design To allow for each power circuit to be easily removed for quick maintenance and troubleshooting.
- Each phase with individual inverter supporting Characteristics will not be violated under 100% unbalance load.
- Protection against detaching and floating of the neutral of input power supply Ensure the safety and stability of the UPS power output.
- Protection from user error Advanced circuitry prohibits damage to the system when the user makes an operational mistake.
- Intelligent charger with temperature compensation Prolong the battery life expectancy. And with huge charging power (selectabl
Overview
The Vesta series provides comprehensive protection and high power density in small and economic package. Compared to traditional UPS towers of the same size, Vesta UPS is more compact and offers greater comprehensive power protection against surges and spikes. Equipped with a voltage stabilizer, this UPS will continue providing clean and stable power to connected equipment while its embedded microprocessor controller guarantees high reliability, perfect for any home or small office applicatio
