The LHUG-150-N is an ultra compact Mil/Aero multi-standard, voltage and power conditioner dedicated to Gaia Converter's latest generation «N» DC/DC converters (i.e with 9-60Vdc permanent input voltage).

The LHUG-150-N is designed to comply with the additional input requirements of 24/28Vdc Mil/Aero buses such as :
  - input inrush current limitation,
  - transient input voltage,
  - transparency due to brownout,
  - +/-100V reverse protection.

The LHUG-150-N allows setting the output power protection limit as well as reducing EMI thanks to Gaia Converter’s bi-phase synchronization drive of MGDD converter. 
The LHUG-150-N has been designed to easily build complex multiple output architectures up to 120W .

It complies with the followings standards :
 - MIL-STD-704A/D/E/F, MIL-STD-1275A/B/C/D/E,  MIl-STD-461,
- EN2282, AIR2021E and many others

The combination of LHUG-150-N, the MGDD series of DC/DC converters and the FGDS filter series, leads to size, thickness and weight optimization of Mil/Aero multiple output DC-DC power supplies.

Modes of Operation

The LHUG-150 features 3 modes of operations:

Normal mode : when the input voltage is above Vistart and below Vilim, the LHUG-150-N bypasses the input to the
output through an internal diode.

Power Fail (PF) Mode : When the input voltage is below Vistop and the Hold-up capacitor connected to VC is charged,
the LHUG-15-0N opens its Vi to Vo link, and connects Vo to the charged capacitor through Vc.

Limitation Mode : when the input voltage exceeds Vilim, the LHUG150N enters into a limitation mode of operation,
in order to provide a constant output voltage equal to Volim.


. Models

Gaia's LHUG-150 High-Reliability Hold-Up module is designed for higher operating temperatures of -40 to +105°C (optional -55°C) for typical military & airborne applications:


Available Options (see specs for details):
• T = -55°C Start-Up Temperature
• S = Screening & Serialization
