Construction:

SSR: Resistor is made by fully welded construction using superior material and processed
in the controlled atmosphere so as to give very high value addition in the form of reliability and long life. The solder dipped terminal and clear marking make the use of resistor comfortable.

 

Electrical Characteristics

DERATING: The power that the resistor can dissipate depends on the operating temperature.

Maximum dissipation (Pmax) in percentage of rated as a function of ambient temperature (Tamb)

Application Information:

These types of resistors are typically used for the following applications:

1)     Discharge resistors

2)     RC Circuits

3)     DC stage of power supplies to absorb the breaking energy of trains

4)     Braking systems of AC Drives for elevators / lifts / cranes / trains
