Online UPS 3/3 phase 2017-09-01T22:38:57+00:00

ONLINE UPS (3phase input, 3 phase output)

The 3 phase input and 3 phase output UPS some time called 3/3phase UPS. These UPS accept three phase
power supply in four wire configuration(Phase R,Y,B, Neutral), and also supply output power in same phase configuration .
The input voltage, Frequency, Input voltage range along with battery bank voltage depends on UPS capacity and models.
We offer these UPS for wide application range starting from basic small data-center to medical facility,hospitals etc.

“The NECS Online UPS System is a true online sine wave UPS that provide the clean power to your precise and mission critical equipment, regardless of any disturbance on incoming AC power. The system offers many advance feature to give maximum reliability with flexibility of various configuration at the lower cost of electricity bills. With NECS Online UPS you have complete peace of mind”

Employing the latest IGBT rectifier technology, offers an input power factor of greater than 0.99, and input current distortion of less than 3%*. Therefore it does not pollute the input utility supply or other devices sharing the same utility source. High speed IGBT inverter gives low output distortion and clean sinusoidal waveform for excellent performance and high reliability. NECS uses the most advanced DSP technology. Using high sampling rate possible only with DSP, output and system parameters are tightly controlled and maintained throughout the various modes of operations. Proper testing, charging, discharging and management of the battery system is very important aspect of the UPS control system. In the NECS UPS, the batteries are constantly monitored by an intelligent battery management algorithm. Any fault detected in the batteries is immediately reported to the user. In situation where the utility supply is relatively stable the can be set to energy saving ECO mode. The load is never in danger as the switching is done by high speed dynamic bypass. System can be managed and monitor via serial communication, LAN (SNMP), GPRS (SMS). User can monitor relative data on analog style meter along with digital meters, the graphical flow of system can seen realty. User can log data, can plot graphs, can schedule the operation system. If system is connected to the LAN via SNMP card the system can be manage remotely any where in the world. If GRPS modem is used, user can controlled the system and receive the SMS for critical condition, like power-failure, low battery, overload conditions.

User Friendly Display and Communication

The LED mimic diagram indication of real time status and power flow through the UPS, LED indicates the status of major modules. The neatly displayed push buttons give function such as menu selection inverter startup and shutdown emergency shutdown and alarm. The large LCD graphical display provides an array of performance parameters, fault information and event log that are useful for troubleshooting Communication to the outside world is never a problem with the NECS UPS. The system provides voltage-free relay contact of common alarms, RS-485 signals for remote monitoring, and SNMP for web-based monitoring. In addition, each system comes with a standard monitoring software that can be used to monitor a single unit or units in parallel through RS232 or Modem connection. With self-diagnosis and self-protection, audio and visual alarm indications are available and these alarm notification can be sent by e-mail or paging to the service.
