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.
