Enclosed Resistor Modules, Enclosed Transistor Modules
Snubber Braking kits are available:
•
as an Enclosed Resistor module for use with an AC drive containing a built-in transistor switching circuit
(such as the GV3000/SE Bookshelf AC drive) or for use in conjuction with an enclosed transistor module
(M/N M3575T__)
•
as an Enclosed Transistor module (M/N M3575T__) for use with AC drives that do not contain a built-in
transistor switching circuit and for use with the enclosed resistor modules (M/N M3575R__)
Note that all of the Enclosed Resistor modules and Enclosed Transistor modules are rated for a maximum
on-time of 60 seconds at a specified duty cycle (see tables 1, 2, 5 and 6).
For GV3000/SE Bookshelf drives: Refer to tables 1, 2, and 3 to ensure that the Enclosed Resistor kit
matches your drive.
For AC Drives requiring both an Enclosed Resistor kit and an Enclosed Transistor kit: Refer to tables 4,
5, and 6 to ensure that the braking kits match your drive and your braking horsepower requirements.
Snubber Resistor Kits (M3575RH__, M3575RL__)
The figure below depicts the breakdown of the Snubber Resistor kit part number.
Enclosed Resistor Braking Unit Fault Output
Enclosed Resistor Braking units have one normally-closed contact (NC) rated at 1 amp @ 24 VDC or
0.5 amp @ 115 VAC that opens on an overtemperature fault condition ( 85 C or higher).
