Output Power: 51 - 100W; Output Type: Single; Output Frequency: 50hz; Output Current: 0-5A Model: -60-12 note: 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 Celsius of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12 inch twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance: includes set up tolerance, line regulation and load regulation. output DC voltage 12V Voltage tolerance +/-1% Rated current 4.5A Current range 0-3.5A Rated power 54W Ripple&noise 100mvp-p DCvoltage ADJ.range +/-10% input Voltage range 90-264VAC,127-373VDC frequency 47-63HZ AC current 1.2A/110VAC,0.65A/220VAC efficiency 82% Inrush current Cold start current 25A/115VAC,50A/230VAC Leakage current Less than 1mA/240VAC protection Over load Rated output power105%-150% start over load protection protection type: hiccup mode,auto-recovery after fault condition is removed over voltage 15.6-17.8V protection type: cut off output voltage,diode clamp environment Working temp,humidity -20 Celsius-+60 Celsius,20%-90%RH Storage Temp,humidity -40 Celsius-+85 Celsius,10%-95%RH non-condensing Withstand vibration 10-500HZ,2G 10min/1cycle,period for 60 minutes,each axes safety Withstand voltage I/P-O/P: 3KVAC I/P-FG: 1.5KVAC O/P-FG: 0.5KVAC Isolated resistance I/P-O/P,I/P-FG,O/P-FG: 100M ohms/500VDC Fit Standard Safety standard Fit UL1012 EMC standard comply with EN55022,CLASSA colour: white Material: ABS+ electronic components size: 9.3 x 7.8 x 5.6cm Package Contents: 4 x Rail type power switch Only the above package content, other products are not included.
