EM - 48 Electronic Modules Ver. 0002
EM.7 RESISTOR MODULES: RM-15, ER.
These modules are designed for dissipating the energy excess at the Power Bus when
requiring a Ballast resistor with greater power than can be dissipated inside the Power Supply
module. They do not need an external power supply.
Stackable module RM-15.
The module can be mounted on either side and it has a safety thermal switch. Next, the
general characteristics of the module are described, its derating graph and the power
connector data.
The last section of this chapter shows the module dimensions.
The PS-65A and XPS-65 must be connected to two RM-15 modules in
parallel. The PS-25A, PS-25B and XPS-25 must be connected to a single
RM-15 module.
The Compact Drives must never be connected to an only RM-15.
