DC-Transformer 145-12-SD
Converter can be used in various applications
Key figures
- ultrawide input voltage range: 16 ... 100 VDC
- very high efficiency: up to 95%
- peak input voltage: 125 VDC
- output voltage / max. output current: 12.0 VDC / 12.0 ADC
Applications
Ultra-compact DC-DC converter with very high power density and excellent thermal properties. Customer specific adjustments easily configurable. In the E-version, the optional reverse polarity protection diode is built in to prevent reverse flow of current during discharge from active loads like batteries. See also our Master 14X.
