48v transfers to 24v switch type DC-DC

Mar 14th, 2012

Brand: TEN-POWER

Name: 48v transfers to 24v switch type DC-DC

Type: LM78H24-300

About products:

Switch type DC-DC LM78H24-300 research and develop produce, isolate module, DC-DC of steady voltage, for TEN-POWER, input the intersection of range and 36-72v, steady voltage export 24v, 300mA.

The products are detailed:

Product performance n The input range n pin compatible traditional 78xx series n that the switch type, efficiency are up to 95% n 9-72VDC does not need extra fin n to short out and protect, overheated to protect n low line wave, noise n and meet UL94-V0 requirement n MTBF> N working temperature of 2 million hours: -40 ℃- +85 ℃Products summary LM78Hxx-500 of TEN-POWER subminiature, high-efficiency switch voltage stabilizer in series, have ultra to input the range into while being wide, can substitute the end line voltage stabilizer of traditional 78XX series three directly. It is with high efficiency and generating heat low, does not need the fin while using. Apply to car electron’s supplying power extensively, some (POL) of load that voltage such as the industrial electric energy meter are with great fluctuating range Field of supplying power.
