Power Supplies
GL Series: Single & Multi Output Switchers
The new GL series provides a broad range of AC/DC power
supply solutions that covers power ratings from 25 watts to
250 watts for use in various industrial applications requiring
standard footprint size and very high reliability.
These low-profile AC/DC switchers offer universal input
voltage with no switches or jumpers, ideal for higher volume E137632
worldwide applications.
