|
|
Available to Order
Item Number: HEB3
|
Our HEB3 Series of DC-DC converters features an extra wide input range (4.5–18 V, 9–36 V and 18–75 V), 1,600-V isolation voltage, wide temperature range (-40 to +105ºC) and high efficiency up to 83 percent. Housed in a SIP 8 package, the devices have no minimum load requirement and include remote ON/OFF, short circuit protection and undervoltage protection. The RoHS and REACH-compliant HEB3 Series is CE marked and meets UL 60950-1, EN 60950-1 and IEC 60950-1 standards.
