SKU: PSA50 Category:


A portable resistive load bank comprising 12 individual switched load resistances arranged in three banks of four for Star or Delta connection.

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 (PSA55) and Inductive (PSA60).

The enclosure has ventilation holes and carrying handles for portability.

Key features:

  • For use as a single or three-phase load
  • Four selectable load values on each bank
  • Works as a balanced or unbalanced load in three-phase circuits
  • Totally independent banks to allow connection as a star or delta load
  • Needs no external supply
  • Includes circuit-breakers on each bank for circuit protection
  • Coloured, shrouded sockets for increased laboratory safety
