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
