Description
This rectifier package is made for the D−Series Motor Brake. It provides either full
wave rectification (low voltage) or one−half wave rectification (high voltage) of AC
voltage input. The standard D−Series VAC Motor Brake has a rectifier located on the
brake coil internal to the brake. If the brake initially had the incorrect coil or was wired
incorrectly, this internal rectifier could be blown. The resistance of the brake coil must
be measured between brake leads B4 and B5 to ensure that the brake coil is the
correct coil and still intact. The proper resistance values are shown in Table 1. Only
if the coil resistance is verified to be correct should this replacement rectifier package
be used. This package is capable of operating at any of the standard D−Series Brake
nameplate voltages 104 through 575 VAC, 50 or 60 Hz.
Mounting
The Replacement Rectifier Package may be placed inside the motor conduit box.
The Replacement Rectifier Package dimensions are shown in Figure 1.
