200W Switch Mode Power Supply with 5V 12V 15V 24V 48V Constant Voltage
The main advantage of the switching power supply is greater efficiency than linear regulators because the switching transistor dissipates little power when acting as a switch.
Other advantages include smaller size and lighter weight from the elimination of heavy line-frequency transformers, and comparable heat generation. Standby power loss is often much less than transformers.
Features :
• AC input range selectable by switch
• Protections:Short circuit / Over load / Over voltage
• Cooling by free air convection
• 100% full load burn-in test
• Fixed switching frequency at 83KHz
