Tiger - HOT - Anti-Tank System
HOT guidance computer - Power Supply

HOT is a powerful guided missile system. It has a range of more than 4,000 meters and can be launched from wheeled vehicles or helicopters.

HOT 3 can penetrate most modern armours. Due to its tandem charge even reactive supplementary armours are rendered ineffective.

HOT 3 is resistant to jamming and can be used at night, in limited visibility and under all weather conditions.

The APCON HLMD Power Converter is a customer specified multi output DC/DC-converter with nine output voltages to provide power for the HOT guidance computer.

The power is provided by the helicopter DC-grid.
The operating voltage is 28VDC. Internal EMI-Filters reduce the conducted emission (CE) and control the conducted susceptibility (CS) in accordance to MIL-STD 462. More than 90% of the EEE-parts are SMD (surface mounted devices)

This APCON product uses high density design at very small dimensions.

The unit operates over the full military temperature range.

APCON is contract holder of the series production.
