Applications :-
• Off peak loading and periodic testing of generator sets.
• Testing of battery banks and Uninterruptible Power Supplies.
• Dynamic braking resistors for electrical motors.
• Energy dumps for electro magnets and wind turbines
Design: -
High quality mineral insulated, tubular, incoloy sheathed resistors are mounted into a powder coated galvanised sheet metal enclosure.
An integral impeller fan provides forced air cooling and a thermal airflow switch and fan motor interlock ensure that the elements are not energised without adequate airflow.
A terminal box is provided which houses all switchgear, selector switches and required instrumentation and external connection is to stud terminals.
A separate 230V/1Ph/50Hz supply is required for loads other than 230V/1Ph/50Hz or 400V/3Ph/50Hz to energise the control and fan circuits. Smaller units are fitted with lifting handles and castors; larger units have wheels or skids and lifting points as required.
