The WDY series product is the isolation constant
pressure input constant voltage output series, this kind of product
has the efficiency high, the precision high, the stable performance is
good and so on the characteristic. It is suitable for the
digital signal processing electric circuit and the input voltage
change not big analogous circuit, specially is suitable to requests a
higher electric circuit and to the noise sensitive electric circuit to
the voltage stability. When the input voltage range of variation
surpasses ±10%, should use KW (width voltage input) the series
product. Yaohua WDY XXSXX-1W series general characteristic:
Insulation strength: 1000VDC short-circuits the protection: Has
Dielectric resistance (note 1): 1000M Omega
minimum value

Operating temperature: -40 ?~85 ?nbsp;coolant conditions: Nature 空冷
Memory temperature: -40 ?~125 ?nbsp;
Sheathing material: Anti- burns the
heat-resisting plastic
Average non- fault time: >80 ten thousand hours
When work 温升: 30 ?maximum values, 20
?typical values Yaohua WDY XXSXX-1W series input characteristic
Input voltage type 5V, 12V, 15V, 24VDC
The input voltage sufficiently permits the range of
variation Vin±5% (Vin±10%)
Biggest input voltage value (note 2) Vin+25% Yaohua WDY XXSXX-1W series input level
Full load output 1W
Output voltage type 5V, 9V, 12V, 15VDC,
Output voltage accuracy . ±2%, (±1%)
Linear voltage regulation rate (note 3) 0.5% max
Load regulation rate 0.5% max
Temperature drifting coefficient 0.02%/ ?typical value
Ripple and noise (20MHz band width) 20mVp-pmax
Time full load efficiency 72% typical value
(±5%) 68% typical value (±10%) Note 1: Between the out-port and the outer
covering in the ambient temperature 25 ? under the humidity 70%
condition, adds time the 500VDC voltage obtains.
Note 2: The input voltage surpasses this value possibly to
be able to create the damage which the permanence cannot be restored.
Note 3: Under full load condition in input voltage ±10%
range of variation, output voltage along with input voltage rate of
change
Note 4: Besides specially indicates, all data all
are in the ambient temperature 25 ?tests obtained.
