Paddy Jackson got Ulster on the board in the fifth minute, scoring a well struck penalty from 40 metres out.
The hosts' went further ahead in the eleventh minute, eighth-man Nick Williams peeling off the back of a driving maul to cross the whitewash. Jackson, successful from the tee extened the lead by 13-points.
Williams scored his second try on the half-hour mark, breaking away from a scrum. Jackson made no mistake, cementing a 20-0 half-time score.
It wasn't until the 63rd minute that the hosts added their third try, Browne going over. Jackson was unsuccessful with the conversion.
