110996

The Allen-Bradley/Rockwell Automation 110996 armature pulse transformer and snubber board is a spare part that can be ordered for the Bulletin 1395 product series. This series of drives is intended for industrial environments where there is a need for additional devices that could enhance the speed and control capabilities of the system. The 1395 drives for which this spare part is intended are manufactured in versions with input voltages from 230 to 480 Volts AC and with power outputs from 40 to 200 Horsepower. The current range for these drives is between 111 and 345 Amps. The 1395 drives have three major hardware component categories: control boards, interface hardware for control/power, and power hardware. The drive consists of component assemblies such as armature bridge components, field bridge components, peripheral devices, control boards, power distribution blocks, communication boards, and optional components.

The 110996 spare part is an armature bridge hardware component. This component is an essential part of the hardware assembly that is providing the necessary electrical protection for the drive. The 110996 pulse transformer is placed on a power board and it is used for ensuring the gate firing pulses and voltage isolation for the armature SCRs. The pulse transformer/snubber board combined component is mounted directly to the bus bars of the armature bridge. In addition to that, the board has R-C networks that are used for protecting the SCRs in the case of transient voltage. Other components and functionalities of the 110996 armature bridge include an AC line reactor, AC current feedback, suppression of the surges, SCR packaging, DC current sensing, synchronization, DC contactor, and connections for bridge output. The 1395 industrial drives can be used at ambient temperatures of up to 55 degrees Celsius (131 degrees Fahrenheit) and stored at a temperature range of 0 to 65 degrees Celsius (32 to 149 degrees Fahrenheit). The drive should be kept in an environment with 5 to 95% relative humidity (non-condensing) and in locations that do not contain dirt, dust, or moisture.
