The transfomer is anideal ac step-up/down power supply, with advantages of no wavform distortion, high efficiency, elegant appearance, ease of use , effective operation for a long term, etc.It is sulitable for imported electrial appliances.
JBK3 machine control transformer
Use products
It is suitable for AC circuit of 50-60hz,output rated voltae less than 220V,inputrated voltage less than 500V,worked as control power supply for mechanical equipment and general electrical appliance and as power supply for work lighting and signal lamp.
It incorporates a full metallic shielding (copper /aluminum) between primary & secondary winding
Isolation transformers are being used to protect electronic & sensitive creative equipment such computer & peripherals medical instruments, digital machines & cnc m/c from the excessive line voltage transient, spikes/surges which produced in the system. Apart from this, isolation transformer also obstructs those disturbances that are generated by the noisy equipment from being injected into the power line i.E. It filters common mode noise usually an attenuation of approx. 30 db.
In shielded transformer, 4 low impedance path exist for noises to pass to secondary & vice versa. These paths are:
- high value of coupling capacitance.
- maximum leakage of magnetic field.
- leakage current
- static transformers of electric noise.
The multiple shielding techniques employed in isolation transformers reduce the inter winding capacitance below to 0.005 pico farad & increase d.C isolation to over 1000 m ohms.
Application of isolation transformer
ò protection of microprocessor based machines from damage & data loss
ò where ground of equipment cannot be earthen
ò when no current leakage is permitted in equipment
ò when protection is needed against high frequency line losses & strong surges.
