4:1 Wide Input Range


Industrial DC-DC Converters in SIP 8 Package

Our HEB2 series of DC-DC converters features an extra wide input range (4.5–18 V, 9–36 V and 18–75 V), wide temperature range (-40 to +105º C) and high efficiency up to 82 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 HEB2 series is CE marked and meets UL 60950-1, EN 60950-1 and IEC 60950-1 approvals.
