Description

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

• 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

Electrical & Mechanical Options

• Rack Mount: Converter fitted into 19″ x 2U subrack.

N+1 Redundancy Rack Mount IEXT DC-DC Converter with front removable power modules

• DIN Rail Mount: Using DIN rail clips.
• Fork Hoist Use +FORKHOIST, models below have been designed for Forklift applications.

Special DC-DC Converters for Forkhoist – Forklift Applications

At Helios Power Solutions we have developed a special range of DC-DC Converters which have in-built input surge protection.

• Undervoltage Lockout: Available on IEXT/LV models, Lockout at 10.2V. auto reset at 12.4V, add suffix -UV
• Use with laptops: Some laptops require a “Sense” the diode is replaced with a resistor and the D+ terminal becomes the “Sense” terminal
