Characteristics:

Isolation Transformer:

The Isolation Transformer at the output provides galvanic isolation. A UPS without isolation transformer at its output may cause danger to the connected loads in case there occurs a short-circuit in the IGBT blocks of the inverter unit. In that case there is a high probability that the connected loads will be burnt due to high DC voltage. Another advantage of the galvanic isolation transformer is that it eliminates the peaks (electrical noise or instant peaks) that might appear at the phase, natural or earth line. For example, in a rainy day if there hits a lightning at the input, the electrical noise will not be able to pass though the output voltage. As a result the load remain safe.

Power Factor Correction (Optional):

Power Factor Correction unit is available at the input stage of IPC 3 Phase UPS System. While the input power factor is around 0.8 in a normal device without PFC unit. The neater the power factor to 1, the less electric bill is paid for the re-active power used. At the same time the system efficiency is enhanced and less current is drawn at the UPS input. As the input current is less, you would be benefited while purchasing a generator with low current ration. Another advantage of using a UPS with PFC unit is that it does not distort the mains supply. As a result the other electronic devices connected to the mains run safely without any interruption.

Eco – Mode (Optional):

Eco-mode is a low cost UPS operational mode, which provides high efficiency (97%) with respect to the user electric bill. If the bypass exists in the desired voltage range and the harmonic distortion is not so high, the loads can be fed from bypass instead of from inverter output. As soon as the bypass failure occurs, without any interruption the inverter output starts feeding the load. The user can also manually manually adjust the UPS to either Normal or Eco-mode.

IGBT & PWM Technology:

Widely used and developed semiconductors, IGBT (INSULATED GATE BIPOLAR TRANSSISTOR), are used in the inverter part of the UPS. With sinusoidal Pulse Width Modulation Technique, maximum operational efficiency is obtained and thus even the non-linear loads are fed with precise sinusoidal signals.

Parallel Configuration (Optional):

Parallel configuration is a system, which ensures more sensitive and reliable operation of the UPS to continue feeding the loads. Because, in even if one unit of the UPSs goes out of order, the other units still operate and thus ensures a continuous feeding of the load without transfer in this system n+1 units can be connected in parallel and thus altogether increase the total capacity of the system. In way, whenever add an extra unit to feed a larger load system.

Hot Stand – by Configuration:

1. Feed one (priority) or two (priority & normal) load banks depending on the application need.
2. Increase the reliability of the priority load.
3. Increase the maintainability.

Easy connections:

Can be implemented in the existing installation regardless of the UPS size, the generation (of device, technology or control mechanism).
