Module Parallel Voltage Tolerance
CmA ±10 mV
CmB ± 10 mV
CmC ±10 mV
CmD ±20 mV
CmE ±10 mV
CmF ±10 mV
Special parallel connection links (CX18P1) can be fitted to CoolMod modules to reduce wiring
complexity. These Parallel Links can be fitted by the installer or added at the factory during
configuration.
To Parallel Connect CmE-F CoolMods
• Turn on module current sharing by adding a jumper on J1017 Connector located on
the Comms Board of the CoolX1800.
Jumper: Harwin – M22-1900005, 2 x 1 2.00 mm Pitch
•
Attach the positive and negative parallel links to the outputs of the modules. (There
is no need to trim the modules together as they use a Master / Slave mode of
operation to share load)
•
Trim the Master module to the desired output.
•
If remote sensing is used in the application, connect both – Sense lines to the low
side of load and connect both + Sense lines to the high side of load
