These products apply to:
1) Where the voltage of the input power supply

is fixed (voltage variation ≤ ±10%);
2) Where isolation is necessary between input
and output (isolation voltage ≤5200VDC);
3) Where the regulation of the output voltage

Output Voltage Regulation and Over-voltage
Protection Circuit
The simplest device for output voltage
regulation,
over-voltage
and
over-current
protection is a linear voltage regulator with
overheat protection that is connected to the input
or output end in series (Figure 2).

Overload Protection
Under normal operating conditions, the output
circuit of these products has no protection
against overload. The simplest method is to
connect a self-recovery fuse in series at the input
end or add a circuit breaker to the circuit.
No parallel connection or plug and play.
APPLICATION NOTE
Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum
output load is not less than 10% of the full load, and that this product should never be
operated under no load! If the actual output power is very small, please connect a resistor
with proper resistance at the output end in parallel to increase the load; or use our company’s
products with a lower rated output power (FB_S-1W).
