Economical ● Four apparatus of similar resistance can be run simultaneously● Reduced maintenance and repairing cost as low probability of burnouts and short circuits ● Less than 10% dissipation of energy as heat. ● No active cooling needed, hence no moving parts which may need to be replaced. Safety ● No shock from accidental contact with single output due to high insulation between primary and secondary windings of transformers● Short circuit proof due to special motherboard design
