Description

The Portable Capacitive Load Bank is a robust steel enclosure that contains three banks of switchable capacitive loads. Each bank of capacitors 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 capacitor into circuit. This allows students to create and study the effects of balanced or unbalanced capacitive loads. Each bank of capacitors includes a thermally operated circuit-breaker to protect the loads. Each capacitor of the load bank includes a high-value discharge resistor that safely discharges any d.c. electrical charge that remains after experiments. This helps to prevent electrical shocks when the students disconnect the circuits. The value of the discharge resistor is too high to affect any experiment results. 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 Resistive and Inductive. The enclosure has ventilation holes and has carrying handles for portability. Note: This load bank only works correctly with 50 Hz or 60 Hz circuits (not both). You must let us know which you need when you place an order.
