Dry-Type Industrial Transformers
Marcus dry-type distribution transformers are easy to install and offer advantages over competitive brands. They are compact to save scarce floor or wall space and are all supplied with wall or floor brackets and channels.
Industrial Control Transformers
If the unit will be installed inside a cabinet or panel, choose our option style (MO) with standard screw terminals or with terminal block (MTB) or the finger safe encapsulated model (MTS). For standalone installations, we have the closed type (MC) and an epoxy encapsulated model (MEC) for harsh environments.
Auto-Transformers
Auto transformers are often chosen as an economical alternative to distribution transformers when electrical isolation between the primary power source and the secondary load is not required. They are used to match the supply voltage to the specific equipment voltage required and do so by tapping off of a common winding, therefore reducing both the size and the weight of the transformer.
Line Reactors
After decades of experience, Marcus offers a vast array of trouble-free line reactors to meet any customer’s needs. Marcus reactors feature heatproof insulation, low heat dissipation and most importantly, elimination of saturation under extreme overloads at double current value.
