The ULK-LOD1 is a flexible Single-Phase/DC Load developed to operate in conjunction with the ULK-THY3 thyristor rectifier or ULK-INV4 inverter systems. These systems were developed for the Power Electronics teaching environment to provide both undergraduate and postgraduate students with a complete, flexible, digitally controlled low power Power Electronic platform. The ULK-LOD1 contains a tapped inductor, resistive and capacitive elements with switches that enable students to explore the effects of different load types on thyristor rectified outputs. In addition the unit can be used as a single-phase inverter load. The ULK-LOD1 is interlock protected against operation without the cooling fan. |
