Description
About i6et Industrial Monolithic UPS System:
i6et industrial monolithic UPS has IGBT based rectifier & inverter with inbuilt isolation transformer, bi- directional static switch. This offers true online double conversion power technology (VFI SS 11 – voltage and frequency independent in accordance with IEC 62040- 3).
It has compatibility with SMFB, VRLA, Lead acid, Ni- CD, Lithium-ion batteries and has all kind of configuration options such as Capacity Enhancement
(CE), Parallel (N+1) and/or dual-bus (N+N) applications to provide the ultimate solution.
It has a relatively simple topology which offers an excellent value for money solution for critical industrial processes. It is normally regarded as the ultimate solution to power problems by providing both uninterrupted power backup and power conditioning. It protects the load from all AC utility supply anomalies i.e. Blackouts, Brownouts, Surges, Spikes, Dips, Harmonics etc.
Key Highlights:
Improves Grid healthiness (IGBT RECTIFIER)
It is highly compatible with upstream without any additional filtering or over sizing.
With integrated PFC (IGBT rectifier technology), the harmonic distortion on the input line significantly reduced (THDi <3%) and achieve input power factor near to unity (upto 0.99).
Galvanic Isolation Transformer (Inbuilt)
It is highly compatible with upstream without any additional filtering or over sizing.
With integrated PFC (IGBT rectifier technology), the harmonic distortion on the input line significantly reduced (THDi <3%) and achieve input power factor near to unity (upto 0.99).
Double wound isolation transformer at the inverter output as part of the inverter circuit inside the UPS cabinet, provide galvanic isolation between the load and the battery with improved versatility in system configuration, allowing:
— Better load protection from DC/Battery problems — Flexibility for common/independent input supply — Bypass line protected against DC bus fault — Better fault handling capacity between phase and neutral on load side
Cater High Starting In-rush
Manual Bypass Operation with inter-locking facility
Low Footprint & High Efficiency with In-Built Transformer UPS
Low footprint UPS with In-Built isolation transformer is the rarest combination, where Hitachi can serve at 2.35m2 for 600kVA floor space and up to 94% overall efficiency considering in-built transformer losses.
Manual Bypass Operation with inter-locking facility
Manual bypass operation is make before break >> 0 msec break during transfer from inverter to bypass. This operation is provided with mechanical and electrical interlock to avoid the misoperation.
Power Reliability:
Hitachi dealt with different type of power problems and provided solutions for mission critical process applications. Hitachi UPS offers user-friendly solutions that can be adapted to any system structure and multi- level complexity & provide power without interruptions. This is achieved by precise design, redundant elements, eliminating common failure points. All the internal processes, parameters are controlled & supervised by digital signal processor (DSP).
Battery Bank Safety:
— Hitachi UPS features are designed to get maximum battery life with safety. — DC MCCB with Under voltage (UV) protection, provided in separate junction Box for fire safety and isolation purpose. — Ripple current is controlled to ultra-low limit as battery is not directly connected to DC Bus. — Battery is continuously monitored and automatically select desired charging mode. — Hitachi UPS is having In-built Battery Management System (BMS). Which offers key features like auto battery test, weak battery bank detection. Battery deep discharge, battery over charge etc. — Timer based boost charge facility available to equalize battery voltage during maintenance.
