NPI UPS series phase ( 1-50KVA)
|It is a UPS manufactured by On Line Double Conversion method.|
|It is a simple and economical product to use and manage UPS with basic features and functions that must be equipped as a UPS.|
|The input power is made to be able to accept single phase or three phase (custom designation). Output power is for single phase only.|
| • It is easy to install in a small space due to low sound absorption and small size.
• The characteristics of the product are very good using the IGBT element of the present invention.
• High Technology Designed by PWM method, it is highly reliable.
• Sine wave On-Line System always supplies good quality power.
• It can be used safely because it has passed the electromagnetic test.
• The switch is designed and manufactured as a semiconductor static switch, no noise due to problems or switching.
• Automatic bypass switch and manual bypass switch are configured in duplicate.
• The battery protection function is excellent.
