DC-Transformer 344-24
Key figures
- ultrawide input voltage range: 22 ... 160 VDC
- very high efficiency: up to 96%
- peak input voltage: 170 VDC
- output voltage / max. output current: 24.0 VDC / 2.0 ADC
Applications
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-Transformer 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.
