APPLICATIONS
The E_T-1W & F_T-1W series are specially
designed for applications where a group of polar
power supplies are isolated from the input power
supply in a distributed power supply system on a
circuit board. 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
≤3000VDC);
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.

APPLICATION NOTE
1) Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum
output load
could not be less than 10% of the full 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
(E _T-W2/F_T-W2 Series).
2) Recommended testing 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 greatest capacitance of its filter capacitor sees (Table 1).
3) 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 (Figure2).
4) 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.
5) No parallel connection or plug and play

Note:
1. Operation under minimum load will not damage the converter; However, they may not meet all specification listed, and that will reduce the
life of product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
1. Only typical models listed, other models may be different, please contact our technical person for more details.
