Description
The SFS5 Series has universal AC input and there are 5 models with single output and 2 models
with dual outputs which are all available in two different pin assignments – PCB mount or Chassis
mount. Super compact size with elegant design and high reliability are achieved. CEC compliant
design shows high efficiency and low no-load power consumption. A limited EMI filter is included
and an additional EMI filter to input side is required to meet CISPR22-B EMI Standard.

this has a low VF.
NOTE: To avoid excessive voltage drop and for
improved noise, and short and thick wire should be
used to connect the load. Length below 50Cm & wire
thickness of 4.0A/mm2 are recommended for reducing
wire loss when wire connection is necessary.

5. Over Voltage Protection
10. Withstand Voltage
SFS series are equipped with an over-voltage
protection circuit by zener diode. If zener diode is
opened, Vcc rise up, it becomes possible to
implement an over voltage protection. Ratch on
mode. If zener diode is short, output is shorted.
It becomes possible to implement a short circuit
Protection.
SFS5 series are designed to withstand 3KVAC
(10mA) 1 minute between input output for the
withstand voltage test, the applied voltage must
be increased gradually from zero to the testing
value, and then decreased gradually at shut
down. Especially stay away from use of a timer.
Where a pulse of several times the applied
voltage can be generated.
6. Over Temperature Protection
Temperature protection is provided by a precision
analog circuit that turns the output MOSFET off
when the junction temperature exceeds the thermal

shutdown temperature (130℃ Min. , 140℃ Typ. and
70℃ hysteresis). When the junction temperature
cools to below the hysteretic temperature, normal
operation resumes providing automatic recovery.
7. Line Regulation

8. Load Regulation
Maximum load regulation is maximum output
voltage value change when varying the load current
slowly within the standard output current range.
11. No-Load Power Consumption
No-Load power is the energy used by a device
when it is disconnected from it's load and
performing no function.
12. Short Circuit Protection
By permanently monitoring the feedback line
activity, the IC is able to detect the presence of
a short-circuit. Immediately reducing the output
9. Isolation Resistance
The isolation resistance is more than 100MΩ at
500 VDC when tested with DC isolation between the
output and the case. Make sure that during testing,
the isolation tester does not produce a high pulse
when the applied voltage is varied. Ensure that the
tester is fully discharged after the test.

short has disappeared, the controller resumes
and goes back to normal operation.
