5.PROTECTION
Input Over Current protection
A1Afusein the input circuit loop, if any input over current occurs,The fuse will opened. The power supply will work after a new fuse being installed.
Output Over Voltage Protection
If any over voltage occurs, the power supply should latch off. The power supply will be automatically recovered after the over voltage fault being removed.
Output Current Protection
If any over current occurs, the power supply should latch off before any output exceeds its limit below:
Nominal Current | Over Current Range |
1000mA+/100mA | 0.9-1.5A |
The power supply will be automatically recovered after the over voltage fault being removed.
Output Short Circuit Protection
Short circuit occurred on +12V output should not cause any damage to the power supply but shut down the power supply. The power supply will be automatically recovered.
Over Load Protection
An over protection will be effected when overloading reaches 100%-150% Max. load. The power supply will be automatically recovered.
6. EFFICIENCY/RISE TEMPERATURE
6.1 Efficiency
The efficiency is70% when this power supply is working under typical station.
6.2Casetemperaturerise
Casetemperaturerise is less than40℃when this power supply works in 25℃ambient temperature.
7. SAFETY REQUIREMENT
7.1 Insulation withstand voltage
