LPS170-M Medical Series

110-175 Watt Medical AC-DC Power Supplies

LPS170-M series medically-approved AC-DC power supplies are available with a nominal main output of 5 V, 12 V, 15 V or 24 V, adjustable over a wide 2:1 ratio. Auxiliary 12 V and 5 V standby outputs are also provided. Main output remote sense and single-wire current sharing are supported as standard. LPS170 power supplies provide 110 watts of output power with free air convection cooling. which can be boosted to 175 watts with 30 CFM of forced air. All models have an 8.5 x 4.25 x 1.5 inch form factor and are ideal for low-profile space-constrained applications.
