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.

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).

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
°C
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 (E _T-W2/F_T-W2 Series).

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).

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).

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.
