Publication GMSI10-IN022A-EN-P - May 2010
Refer to the specifications for the specific module for power consumption
and other requirements.
See XM Power Supply Solutions application technique, publication
ICM-AP005A-EN-E, for additional details.
Interconnect Limit
Total current draw through the side connector cannot exceed 3A. A separate
power connection is necessary if the total current draw of the interconnecting
modules is greater than 3A.
Wiring Requirements
Use solid or stranded wire. All XM wiring should meet the following
specifications:
Output Power 100 Watts Maximum (~4A @ 24Vdc)
Static Regulation ± 2%
Dynamic Regulation ± 3%
Ripple < 100mVpp
Output Noise Per EN50081-1
Overshoot < 3% at turn-on, < 2% at turn-off
Hold-up Time As required (typically 50mS at full rated load
* When a fused supply is used the fuse must be a 5 amp, listed, fast acting fuse such as
provided by Allen-Bradley part number 1440-5AFUSEKIT.
TIP
If the total current draw for a row of modules is greater than 3A, consider
connecting power to a module near the center of the rail, rather than at a
module on either end. Insure that there is less than 3A load in either direction
from the module where power is connected.
