The 25-year-old, who has yet to make an appearance for the Welsh club, joins up with League One's bottom side.
Obeng arrived at the Liberty Stadium in 2012 after playing over 100 times for Wrexham, and has also experienced loan spells at York City and Fleetwood Town in the past.
The right-back has been capped four times by England at Under-19 level.
