IEXT-IEHR
Isolated DC/DC Converter 70W – 150W
IEXT & IEHR series have been manufactured by Helios Power Solutions over the last 35 years and it is considered one of the most reliable DC-DC Converters in the market. Our converters have a wide input range from 12V to 110V and output voltage range from 4.5V to 55.2V.
The IEXT Series has a constant output current limit and is suitable for battery charging. Please specify output voltage on ordering. Whether you require a custom DC output or conformal coating for harsh environments, please contact our team of engineer at sales@heliosps.com.au
Main Features
- Isolated input-output – chassis
- Designed for industrial use
- High reliability
- Output over-voltage protection (IEXT)
- Constant current limit for charging (IEXT)
- Input transient/surge suppression
- Short circuit protection
- Reverse polarity protection
- External trim pot for output voltage adjustment
- Output decoupling diode and dc fail alarm standard
- Optional conformal coating
- Optional DC Fail alarm
Output Protection
IEXT(70W): Overload: constant current limit Severe overload: shuts down when output < 5V, power off to reset. IEXT Series is suitable for battery charging.
IEHR(150W): Hiccup mode current limit
