NUTECH – INDUSTRIAL Online UPS 6 kVA – 300 kVA
3-phase Input, 3-phase Output, Double Conversion, Standalone
A Transformer-based rugged UPS manufactured for tough environments
NUTECH has over 30 years of experience in providing advance power solutions for safe & managed power through its existing range of NUTECH – INDUSTRIAL Online UPS System 6 kVA – 300 kVA, 3-phase Input, 3-phase Output. NUTECH is committed to the highest standards of quality and customer satisfaction.
We response to Future Standards & Quality
NUTECH – INDUSTRIAL UPS System 6 kVA – 300 kVA UPS meets all criteria to be titled “Continuous Operation”, and is therefore a True On-line UPS System. A very rugged 6-PULSE SCR (Thyristorised) Bridge Rectifier cum Charger with Built in solid state Automatic float-cum boost Charger with Constant Voltage and Constant Current mode of Charging along with current limiting features are provided. The latest generation state-of-the-art IGBT Bridge in Inverter technology with Instantaneous Sine Wave Control & adaptive PWM technique is used. A key advantage of this technology is that no de-rating of the UPS Power is required when driving non-linear loads.
NUTECH UPS front panel is equipped with back-light Alpha-Numeric LCD Display indicating the UPS operating status and parameters of Input – Voltage, Current, Frequency, Battery – Voltage, Charging Current, Output – Voltage, Current, Frequency and other important information such as Alarms and Indications.
Isolation Transformer & EMC Standards
Due to the Double Conversation technique & Inbuilt Galvanic Isolation Transformer, (Neutral is Electrically and physically Isolated from the Input Power Circuit / Utility Neutral) which ensures no spike & surge in the output. The effective screening of Noises, Transients etc., by the ideally designed filters ensures the output is free from EMI /RFI, which complies all the EMC standards thus providing full safety to the very critical equipments.
