2. Input:
2.1 Voltage
Universal 100~240Vac, single phase
2.2
47 ~ 63 Hz
Frequency
2.3 Current
0.58A Max.
30A Max. / 100Vac ; 60A Max. / 230Vac
(Cold Start At 25 ºC,Full Load)
2.4 Inrush Current
2.5
Efficiency
Eff (av) ≧ 82.22% Min. (At 115 Vac & 230 Vac)
2.6
Power Consumption
Pi ≦ 0.3 W ( At 230Vac & No Load)
※Eff (av) =
E1 + E2 + E3 + E4
E1=efficiency with 25% rated load ; E2= efficiency with 50% rated load
4
E3=efficiency with 75% rated load ; E4= efficiency with 100% rated load
3. Output:
3.1
DC Output
Voltage
+12V ± 5%
Current
2.0A Max.
Regulation
11.4Vmin. ~ 12.0Vtyp. ~ 12.6Vmax.
Ripple & Noise
100 mV Max.
Total Power
24W Max.
Remark : For ripple & noise measurement, use a 20MHz bandwidth frequency oscilloscope, and add a 0.1μF multilayer Cap. and a
Low ESR Electrolytic Cap. (10 μF ) at output connector terminals. (At nominal line voltage, Full Load)
4. Protection :
4.1 Over Voltage Protection (OVP)
15V ( Max. )
4.2 Short Circuit Protection (SCP)
Automatic recovery after short-circuit fault being removed
4.3 Over Current Protection(OCP)
4A (MAX)
Remark : When Short Circuit Protection is activated,the power supply will shutdown automatically.
Once the abnormal condition resulting in the failure being removed, the power supply will restart accordingly. When
Over Voltage Protection is activated, the power supply will shutdown.
