DESCRI PTI O N

The TM66 series of compact, open PCB constructed,

AC-DC switching power supplies are capable of

delivering 51 to 65 watts of continuous power. They

operate at 90 to 264VAC input voltage without the

need of voltage selection. They are ideally suited for

use in medical equipments. All models meet the

safety requirements of UL, CSA and IEC.
