2．Function explanation

2-1

Input Voltage

・ Input voltage range is single phase alternating current

85～264Vac(47～63Hz).

・ We recommend that you do not use this power

supply unit outside of it's normal intended use in

order to avoid any damage or malfunctions.

2-2

Output voltage setting

・ You can adjust Vout by using Output Voltage Adjustment

Potentiometer besides CN501connector.

・ You can increase Vout by turning clock wise and can

turn it the other way when you need to decrease.

・ Please use Vout within the following range.

・

Within +/- 10% rated output voltage.

Note: MFS50-5 can be used only within 5.0 to 5.5V range.

・

Do not use maximum output power.

・

Do not exceed rated output current.

2-3

Inrush Current

This model has inrush current limiting feature.

・

When inrush current limited circuit is on, please turn on

・

PSU after several tens of seconds passed.

2-4

Over Current Protection (OCP)

・

OCP feature will shut down the output when Output

current exceeds 110% than specification.

・

Remove the factor of the overload, then turn off.

Please turn on again after waiting for several minutes.

Don't keep using under the over current load condition

・

for over 10 seconds.

2-5

Over Voltage Protection (OVP)

・

When PSU detects Vout raises more than

specification, it automatically shut down the output.

・

OVP works while input power is supplying.

・

When you need to reset PSU, please turn on again

after several minutes disconnecting the AC input.

・

Please make sure to remove the OVP condition.

Otherwise it may works again to protect PSU.

2-6

Remote ON/OFF circuit

・ You can turn on/off while applying input.

・ You can apply voltage to the RC pin.

Series Operation

・

Following <1> & <2> series operation can be used,

However be sure to use output current below the

Max Iout in small wattage one either of power supplies

which the series is connected.
