DC Output Ripple & Noise

Output Voltage	Ripple & Noise
5.0 Vdc	140mVp-p@25℃
5.0 Vdc	240mVp-p@-25℃

Measure Methods A. Ripple & Noise test：Ripple & Noise bandwidth is set to 20mHZ. B. Use a 0.1uf ceramic capacitor in parallel with a 10uf electrolytic capacitor at output connector terminals for ripple & noise measurements. Fan cooling

Specific Cautions A. The product should be suspended in air or installed on the face of metal when it is assembled, and be avoided to place on the face of non-conducting heat materials such as, plastics, board and so on. B. The space between each module should be exceeded 5cm in order to avoid affecting cooling of power supply.The MTBF shall be at least 50,000 hours at 25℃ at the condition of full loading.Table 1 : Input 5 pin terminal block (pitch 9.5mm)

V- V- V-	Output DC negative pole

Current through the output terminal block should not exceed 20A, so never overload test and work in that kind of condition. Or the terminal block will be damaged because of high temperature.

The power supply must work at the condition of insulation and make sure the terminal post of cable is insulation. Besides, make sure the product is grounded well and forbid touching the cabinet to avoid scalding hand.
