Product Description: DC-Converter 344-24

Galvanically isolated DC/DC converter, 24V, 2A for customised pitch systems. The robust DC/DC converter is the first-class power supply for further pitch products in the low voltage range for onshore and offshore wind turbines from 200kW to 6MW. Due to the ultra-wide DC input range of 22…160VDC the Demke DC-Converter 344-24 can be operated reliably at different supply voltages. Built from the highest quality components, this DC/DC converter achieves a MTTF value of 1`650`000h, which was calculated according to SN29700 at approx. 70°C.
