HEAVY DUTY .Designed to be safe and reliable source of low voltage D.C. for use in class
rooms. Allows teachers to
conduct experiments requiring a variety of direct current voltages while avoiding the
decrease
characteristics of partially exhausted dry cell. Comprising heavy duty transformer wound with copper wire
with
high lamination to avoid losses, bridge rectifiers (consists of full wave silicon diode bridge rectifier) with
jewel light
and safety fuse.
