These are transformer based adaptors, in which the output varies linearly in relation with input supply. The distortion will be maintained at a least possible level where the noise disturbance should be nil. These adaptors will be manufactured as per customer specifications. In this category AC to AC adaptors can also be manufactured.  These adaptors find application for cordless phones, coffee-maker etc.

These are PCB based models with an wide operating voltage range of 90V to 300VAC. These are light in weight compared to linear adaptors. These are best suitable for applications where the operating voltage is a particular specification to meet with. These adaptors find application for FCT, FWT, POS, Battery-Charger, etc.
