Abstract: A transformer unit for supporting, preferably, medical instruments, while furnishing them with particular levels of electric charge to accommodate their operations or recharging. a mounting member supports the transformer, and a series of modular like instrument supports, each having a base that holds an instrument, and an inclined concaved side upon which the instrument rests, are secured together intermediate a pair side walls and connected to the mounting member. Electrical circuitry provides for the conductance of electrical charge to the transformer, and a series of circuitries, one provided in each instrument support, conveys the transformed charge to each support. Secondary circuitry within each support also conducts the stepped-down voltage to each support base where wiring of a medical instrument may be connected to attain its operation, or where a self contained instrument may be recharged as during nonusage.
