Description
The Portable Resistive Load Bank is a robust steel enclosure that contains three banks of switchable resistive loads. Each bank of resistors is electrically separate, so they can connect as a star or delta load for three-phase circuits. Each bank has a set of switches to bring each resistor into circuit. This allows students to create and study the effects of balanced or unbalanced resistive loads. Each bank of resistors includes a thermally operated circuit-breaker to protect the loads. Students connect the loads to experiment circuits using safety sockets on the enclosure front panel. Students can use this load bank in combination with the other similar load banks to provide variable power and power factor loads. The other load banks are Capacitive and Inductive. The enclosure has ventilation holes and carrying handles for portability. Note: This load bank works with both 50 Hz and 60 Hz circuits
