Data Sheet

EC-LTS1200-410

Liquid cooled heavy duty inductor unit

FEATURES

Extremely compact design: 410 A unit only 23 kg

High enclosure class IP67 – sealed from moisture and dust

Liquid cooled with plain water or water/glycol mixture

Ambient temperature up to +105 °C and down to -40 °C

Allowed coolant temperature up to +65 °C

Robust design withstanding high levels of mechanical vibrations and shocks

Designed especially for highly cyclical loads typical in heavy mobile work machines

Three temperature sensors included for temperature surveillance

GENERAL

The device is a heavy duty external inductance unit designed to be combined with EC-C1200 DC/DC-converter. It allows flexible positioning of the DC/DC-converter and inductor unit and is used to transfer energy between two different voltage levels.

Typical applications:

Boosting battery voltage to higher DC-link voltage

Charging high voltage batteries from higher DC-link voltage
