The 2S7A Series is specially designed for applications where a group of

polar power supplies are isolated from the input power supply in a dis-

tributed power supply system on a circuit board.

These products apply to:

1)Where the voltage of the input power supply is ﬁxed

(voltage variation ≤±±5)ꢀ

2)Where isolation is necessary between input and output

(isolation voltage ≤1000VDC)ꢀ

No Heat Sink Required

3)Where the regulation of the output voltage and the output ripple

and noise are demanded.

Note:

1. Operation under minimum load will not damage the converterꢀ However, they

may not meet all speciﬁcation listed, and that will reduce the life of product.

2. All speciﬁcations measured at Ta=2±°C, humidity<7±5, nominal input voltage

and rated output load unless otherwise speciﬁed.

3. In this datasheet, all the test methods of indications are based on corporate

standards.

Application note

1) Requirement on output load

To ensure this module can operate efﬁciently and reliably, During opera-

tion, the minimum output load could not be less than 105 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.

2) 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).

0.47

3) Input Over-voltage Protection Circuit

The simplest device for input over-voltage protection is a linear voltage

regulator with overheat protection that is connected to the input end in

series (Figure 2).

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 prob-

lem might arise. For every channel of output, provided the safe and reli-

able operation is ensured, the greatest capacitance of its ﬁlter capacitor

sees (Table 1).

Figure 2

4) Overload Protection

Under normal operating conditions, the output circuit of these products

has no protection against overload. The simplest method is to connect

self-recovery fuse in series at the input end or add a circuit breaker to

the circuit.

5) When the environment temperature is higher than 71°C, the product

output power should be less then 60% of the rated power.

6) It is not recommended to increase the output power capability by

connecting two or more converters in parallel. The product is not hot-

swappable.
