3kVDC isolation

The 20DAW4_3 series oﬀers 20W of output, with 4:1 ultra wide input

voltage of 9-36VDC or 18-75VDC, and features 3000VDC isolation,

over current, over voltage and short-circuit protection, as well as six

sided metal shielding.

All models are widely suited for power industry, data transmission

devices, battery power supply and tele-communication devices,

distributed power supply systems, remote control systems, industrial

robot systems etc.

Note:

1. Recommend to use module with more than 5% load, if not, the ripple of the

product may exceeds the speciﬁcation, but does not The maximum capacitive

load oﬀered were tested at nominal input voltage and full load;

2. Unless otherwise speciﬁed, parameters in this datasheet were measured under

the conditions of Ta = 25°C, humidity <75%RH with nominal input voltage and

rated output load;

3. All index testing methods in this datasheet are based on our Company’s

corporate standards;

4. The performance parameters of the product models listed in this manual are

as above, but some parameters of non-standard model products may exceed

the requirements mentioned above. Please contact our technicians directly

for speciﬁc information;

5. We can provide product customization service;

6. Speciﬁcations are subject to change without prior notice.
