Single and Three Phase Resistive Load Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12970
Indian Lab Suppliers supplies the Single and Three Phase Resistive Load (Product ID: 12970) as part of its electronics engineering lab equipment range. It is a trolley-mounted, fan-cooled resistive load bank for loading single-phase and three-phase supplies and generators.
Quick Answer
Three electrically isolated resistor banks are switched in steps by single-pole 10 A MCBs, which also protect them, and a star/delta switch (415 V, 25 A) sets the three-phase connection. On single phase the banks give up to 3.5 kW at 240 V and 15 A in 15 steps; in three-phase star up to 3.5 kW at 415 V, 5 A per phase, and in delta up to 10.5 kW at 415 V, about 15 A line current, each in 5 steps per phase. Balanced or unbalanced loads can be set, and the unit suits static sources as well as rotating machines.

Where This Is Used
Used in electrical machines and power laboratories to load alternators, generators and transformers during tests. The resistors dissipate several kilowatts and get very hot, so keep the fan running, keep the vents clear and connect with the supply off. Smaller and companion loads: Single Phase Resistive Load (Product ID: 12971) and Single Phase & Three Phase Capacitive Load (Product ID: 12972).
