* Dollar supported by risk aversion, Bernanke awaited
* Weak U.S. consumer confidence weighs on sentiment
* Analysts: Dollar may fall on Bernanke testimony
(Adds detail, comment)
By Neal Armstrong
LONDON, Feb 24 (Reuters) - The dollar held broad gains on Wednesday after weak U.S. consumer confidence data the previous day limited risk appetite, and as investors braced for testimony from Federal Reserve Chairman Ben Bernanke.
Currencies generally stuck to narrow ranges as few investors were keen to take big positions before Bernanke begins his Congressional testimony at 1500 GMT. Investors will scrutinise Bernanke's comments for clues to the Fed's interest rate outlook after the U.S. central bank last week raised the rate at which it offers emergency loans to banks, a move it insisted was technical.
Analysts said evidence the economy continues to struggle, highlighted on Tuesday by a fall in consumer confidence to a 10-month low in February, supports the Fed's position that interest rates will stay low, and that Bernanke would retain a cautious stance.
"Confidence data yesterday showed the consumer is still fragile and given weakness in the labour market, the Fed is likely to be at pains not to choke off any recovery. I expect Bernanke to reiterate that rates in the U.S. will stay low for an extended period," said ING currency strategist Tom Levinson.
He added that questions to Bernanke would likely focus on weakness in the labour market and that a cautious tone could lead to slippage in the dollar index <.DXY> towards 80.50.
RBC analysts said in a note they expected Bernanke to say a rise in the fed funds rate was a long way off.
"If so, we would expect this to weigh on (the dollar), lift stocks and reverse the sharp moves seen through yesterday."
The euro edged up, but gains were limited as stock markets struggled to break out of negative territory, keeping investors largely averse to risk. Analysts said this was the main driver of the market in Europe, keeping dollar losses minimal.
By 1220 GMT, the euro was 0.3 percent higher at $1.3550. The single European currency was propped up as some traders further trimmed short positions following broad weakness in past weeks.
The euro hovered near a nine-month low hit versus the dollar last week, on the back foot after GfK data showed German consumer sentiment was set to decline into March, following weak business sentiment data on Tuesday. [
]Concerns about Greece's public finances also kept the single European currency vulnerable to more losses. A ratings downgrade of Greece's four largest banks by Fitch on Tuesday reminded investors of the financial woes facing the country.
European shares <

AUSSIE RETREATS
The Australian dollar <AUD=D4>, often considered high-risk, traded 0.1 percent lower against the U.S. dollar at $0.8888, off a session low of $0.8857 hit on U.S. bank sales. The Aussie retreated from a one-month high of $0.9072 hit on Wednesday.
Technical analysts said Tuesday's retreat signalled a key-day reversal on the daily charts, highlighting potential for further slippage.
It also slipped against the yen, which held gains after rallying across the board on Tuesday on perceived safe-haven demand. The dollar <JPY=> slipped 0.2 percent to 90.04 yen, further retreating from climb above 92 yen last week.
