Thiết bị kiểm tra relay HTI RB10
Features
· Improves current control into low impedance
loads
· Particularly suitable for solid state relays
· 0.5W—1666.5W in 8 steps
· Maximum current 0.2—10A
· Thermal cutout
· Compact & lightweight
The RB10 resistor box is used in conjunction with a current
injection unit when testing low impedance relays and trips,
allowing finer control of the current. The unit is designed for
use with the 100ADM and 200ADM, but may be used with
any suitable current source.
The unit has eight resistance ranges with a maximum power
dissipation of 50W for any one resistor.
