The Bel Power Solutions 350DNC40-12 Series is a 4 kW DC/DC
converter that converts HVDC voltages in hybrid and electric vehicles
to LVDC voltages suitable to power low voltage (12/24 VDC)
accessories.
Liquid or convection cooled DC/DC converter operates at input
voltages from 240 to 430 VDC and delivers power range up to 4000 W
/ 3300 W (liquid / convection cooled model).
Features include very high efficiency, high reliability, low output
voltage noise, and excellent dynamic response to load/input changes.
Input voltage range: 240-430 VDC (300-450 VDC)
Typical efficiency up to 93 %
Up to 4 kW power (max. 16 kW)
Full galvanic isolation between input and output
Liquid or convection cooling
CAN bus serial interface
Adjustable output voltage
Over temperature, output overvoltage and overcurrent protection,
input and output reverse polarity protection
Protection degree IP65 and IP67
E-mark compliant
Hybrid and electric vehicles
Medium through heavy duty, on and off highway vehicles
