Power supply 

PS4D (Roger) power supply unit is recommended to provide 13.8VDC supply to MCX4D expander. 
However it is possible to use other type of PSU if it offers adequate voltage and current parameters. Due to 
relatively high current between expander and PSU, all connections should be made using possibly short 
cables with adequate cross sections. PSxD series PSUs (Roger) are offered with two 30cm/1mm

² cables 

dedicated to supply the expander. Multiple MCX4D expanders can be supplied from the same PSU and in 
such case each connection must be made with individual pair of cables. When expander’s supply voltage is 
too low the battery cannot be fully charged and when the voltage is too high the battery can be damaged. 
MCX4D which is supplied from PSU equipped with backup (e.g. battery, UPS) cannot be equipped with own 
backup battery. 

Note: If the expander is expected to operate with full power in regard of power outputs and battery charging 
(0.9A) then it must be supplied with 6.0A or greater rated current (e.g. PS8D).
