ULTRA ISOLATION TRANSFORMER
NOISE CUT-OFF TRANSFORMER
(Ultra Isolation Transformer)
Noise Cut-off (Ultra Isolation) Transformer cuts off noise, so your machine can perform with musical perfection.
|
|
We have good expertise in designing Ultra Isolation Transformer. These noise cut off transformer is compact in design, cost efficient and perform with musical perfection.
Spikes generated on switching of electrical utilities in Industrial & Commercial environment can damage thyristors, Micro-processors, or other active electronic device. Up to 6000 Volts & high frequency power line Noises produced from spikes can interfere with Digital-Electronic equipment causing change of program, erratic behavior, data corruption, loss of memory etc.
The noise cut-off Ultra Isolation Transformers thus eliminate noises from high frequency and attenuates the spikes to negligible values. This way these protect from such kind of electrical disturbances.

| Ultra Isolation Transformer Salient features |
| |
 |
Symmetrical characteristics allow noise attenuation from sides. |
|
No need for extra filter circuits. |
|
Can be used where different ground potential exists or the ground of the equipment cannot be earthed. |
|
No impedance matching required. |
| |
| Ultra Isolation Transformer Applications |
|
Protect the Computers, CNC Machines and Telecommunications equipment from damage due to electrical noise, spikes etc. |
|
If ground potential of system units are different from each other and are exposed to the effects of instability at
high frequencies. |
|
If ground of the equipment cannot be earthed. |
|
When no slightest current leakage is permitted in the equipment. Especially for computers and CNC controls less than 100 micro Amps is only permitted. |
|
To protect against strong lighting, impulse noise, bus short-circuit, accidental discharge of capacitors etc. When no
slightest current leakage is permitted in the equipment. |
|
When multiple Noise Cut-off transformers are used, the suppression effects increase in proportion. Therefore, the effects
of cascading Noise Cut-off Transformers is remarkable. |
|
To shield large number of electronic equipment which individually also are producing different types of electrical noise at
a common busbar typically CNC machines, Drives, Hardening equipment etc. The use of NCT, being bidirectional, prevents damage due to circulating noise interference within them. |
