Resistive Load

Resistive Load .
RESISTIVE LOAD - didactic equipment It must consist in a single or three-phase resistive step-variable load. Housed in a metallic box.
MECHANICAL FEATURES
The load shall be composed of a rugged metal structure and of a front metal panel.
On the front panel all the controls, the protection, the output terminals and a clear synoptic diagram, shall be collected.
ELECTRIC FEATURES
The load shall be composed of resistances, with possibility of star, delta and parallel connection, controlled by three
switches. This item must be provided also with fuses protection.
As a function of the switch positions, there shall be the following phase values:

Seven position resistance ranging from 123 to 1050 Ohms with corresponding power per phase of 46 W to 400 W

Maximum power in single or three phase connection must be 1200 W.
Rated voltage in star connection must be 380 V, in connection must be 220V, in single-phase must be 220V. 4 mm. safety terminal included on the front panel for the electrical connection.
