THE LAN C SERIES FROM WALL INDUSTRIES
Offering alternate combinations from four different input voltage
ranges; nine different output voltages; regulated and non-regulat-
ed versions; two levels of isolation and three tiers of power, the
LAN C Series of DC/DC converters can be tailor-made to fit
most any low power conversion requirement.

NOTES:
1. All parts are available in non-regulated versions, substitute “N” for “R” in part num-
ber to indicate non-regulated version.
2. Also available with 48VDC in. To specify, insert “48” in part number in place of
input voltage .
3. All models available with 3000VDC I/O isolation. Add”H” onto end of part num-
ber for 3000VDC Input/Output isolation. Case height goes to 0.50”.
4. All DC/DC Converters should be properly fused on front end for protection.
TO 3 WATTS
