*Designing.
applications where a group of polar power supplies
are isolated from the input power supply in a
OUTPUT SPECIFICATIONS
distributed power supply system on a circuit board.
Item
These products apply to:
1) Where the voltage of the input power supply is
fixed (voltage variation ≤ ±10%);
Line regulation
2) Where isolation is necessary between input and
output (isolation voltage ≤6000VDC);
Load regulation
3) Where the regulation of the output voltage and
the output ripple noise are not demanding.
Such as: purely digital circuits, ordinary low
frequency analog circuits, and IGBT power device
driving circuits.

Recommended testing and application circuit
If you want to further decrease the input/output
ripple, an “LC” filtering network may be connected to
the input and output ends of the DC/DC converter,
see (Figure 1).

It should also be noted that the inductance and the
frequency of the “LC” filtering network should be
staggered with the DC/DC frequency to avoid mutual
interference. However, the capacitance of the output
filter capacitor must be proper. If the capacitance is
too big, a startup problem might arise. For every
channel of output, provided the safe and reliable
operation is ensured, the recommended capacitance

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.
APPLICATION NOTE
Requirement On Output Load
To ensure this module can operate efficiently and reliably, a minimum load is
specified for this kind of DC/DC converter in addition to a maximum load (nam ely full
load). During operation, make sure the specified range of input voltage is not
exceeded, 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
No parallel connection or plug and play.
Note:
1. All specifications measured at Ta=25°C, humidity<75%,
nominal input voltage and rated output load unless
otherwise specified.
2. Only typical models listed, other models may be different,
please contact our technical person for more details.
3. Operation under minimum load will not damage the
converter; However, they may not meet all specification
listed.
increase the load, or use our company’s products with a lower rated output power.
