Page 14: Typical Configuration
Engineering Section of this manual MUST be followed when selecting a dynamic load for use with the M3675T unit. Figure 3-1 shows a typical interconnection of the M3675T with the M3575R Resistor Module. For interconnection with other load modules, refer to the documentation supplied with them. -
Page 15: Operation
4.1. UNCTIONAL ESCRIPTION The M3675T Module controls the bus voltage of a variable frequency drive by transferring energy to a resistor. When the drive’s DC bus voltage exceeds a fixed setpoint, the Braking Transistor’s control electronics turns on an IGBT transistor connecting a dynamic load across the DC bus. - Page 16 M3675T This page intentionally left blank.
