BFA105R6

The BFA series Variable Rheostat is produced using constantan (CuNi44) wire, wound onto ceramic formers, with insulated wire to give mechanical stability and good heat dissipation. A leaf spring type wiper, with a ceramic handle is used to vary the resistance. The resistors are protected with a perforated, pressed steel cover and three laboratory terminals are provided so that the unit can be used as a series resistor or potential divider. These are ideal to provide variable current outputs in all laboratory environments.

• Tough steel box construction
• 3 Terminals for divider use
• 10 Times power - short time
• Power dissipation up to 10A
• Operate up to 400°C
