DESCRIPTION
The DC/DC module is a high efficiency DC/DC not in-
sulated switch mode constant voltage generator.
Designed for industrial application where low voltag-
es are required from main.
Power Module VIP 4.5W
Step down converter performs a max 1.8W, 4.5 W
and 12W power conversion.
The output voltages and current level are set up by
design in accordance with customer requirements.
Typical reference values for the shelf solution are:
-single output -12V, ±10%, 0.15A for 1.8W;
-single output -12V, ±5%, 0.35A for 4.5W;
-single output -12V, ±5%, 1A for 12W.
Power Module SM 12W
Power Module VIP 1.8W
