2:1 Wide Input Range


Industrial DC-DC Converters in SIP 8 Package

Our HEA2 series of DC-DC converters features an extra wide input range (4.5-13.2V, 9-18V, 18-36V, 36-75V), wide temperature range (-40 to +105º C) and high efficiency up to 86 percent. Housed in a SIP 8 package, devices have no minimum load requirement and include remote ON/OFF, short circuit protection and undervoltage protection. The HEA2 series is CE marked and meets UL 60950-1, EN 60950-1 and IEC 60950-1 approvals.
