- Enclosed, non-isolated, Adjustable transformer, with Output Volt Meter. On/Off Power Switch (Lighted), 5A fuse & power cord. ^^ - Over-voltage protection, the use of more security. Contact voltage transformer, wide voltage range (0-130V) ^^ - Built-in copper coil, material quality, more secure and durable. High efficiency and with no waveform distortion. ^^ - Suit for home coffee roasting, Motor Speed control, Label Printing Machine, EE Labs, Test for Railroad Switching, Power Supplies, Satellite, Equipment, Telecommunication Equipment. ^^ Please note that most device have surge (when first turn on) much higher than operating amp rating.
E. g, motor with 5 amp rating may have over 10 amp surge, and you will need 10 amp transformer.
