The Bel Power Solutions 700DNC40-12-xG is a 4kW DC/DC Converter that creates DC voltages in hybrid and electric vehicles suitable to power low voltage accessories. Liquid cooled or convection cooled DC/DC converter operates at input voltages from 400 to 800 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. Very high efficiency up to 93 % Input voltage range: 400-800 VDC Up to 4 kW power Full galvanic isolation between input and output Liquid or convection cooled models available 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 E12*10R00-10R05*13669 Hybrid and electric vehicles Medium through heavy duty, on and off highway vehicles 2 700DNC40-12-xG MODEL DESCRIPTION 700DNC40-12-8G Liquid cooled model 700DNC40-12-CG Convection cooled model Mating connectors kit Signal connector housing and pins, HV connector assembled with 3 m cable 700DNC40-CON-KIT-7G including HVIL lines 700DNC40-CON-KIT-8G Mating connectors kit Signal connector housing and pins, HV connector assembled with 3 m cable 700DNC40-CON-KIT-9G Mating connectors kit - housing and pins PARAMETER DESCRIPTION / CONDITION MIN NOM MAX UNIT Input Voltage 400 700 800 VDC Input Current 11 ADC Efficiency Vin = 700 VDC, Vo = 14.4 V, Ionom = 229 A 92 % Input Line Interruption Converter shutdown 390 VDC Input Capacitance 35 F Inrush current External pre-charging circuit required PARAMETER DESCRIPTION / CONDITION MIN NOM MAX UNIT Output Voltage Vo to be trimmed via CAN BUS, 10 bit resolution 9 14.4 16 VDC Liquid cooled model 278 Output Current 14.4 VDC ADC Convection cooled model 229 Liquid cooled model 4000 Output Power W Convection cooled model 3300 Line Regulation Vinmin - Vinmax, 139 A, T coolant = 70C - 0.1 + 0.1 VDC Load Regulation Iout 10 to 90% load, T coolant = 70C - 0.075 + 0.075 VDC Output Voltage Set Point 139 A, T coolant = 25C 14.35 14.4 14.45 VDC Thermal Drift -0.05 +0.05 %/C Periodic and Random 14.4 VDC / Nominal load (Differential Mode 20 MHz) 280 * mVp-p Deviation CAN high / low (Differential Mode 20 MHz) 300 * Load step 1: 10 to 50 % and back Load step 2: 50 to 100 % and back Transient Response Voltage over/under shoot: -1000 +1000 mV Response time within 1 % of VoSET: 1000 s Turn-on Overshoot Vonom, <100 ms 5 % Redundant Parallel Operation Up to 4 converters operating in parallel 16 kW Remote Sense Cable Drop (V) Maximum Load 0.5 V Rise time (Cext = 0 F) 200 ms Power-on-delay (From applying DC input voltage to Vo = 90 %) 1 s Turn-On Delay Power-on-time from PS WAKE UP (From PS WAKE UP ON to 3 s Vo = 90% of nom) Turn-Off Timing PS WAKEUP delay (monotonic Vo fall) 0 100 ms Capacitive Load 14.4 VDC 0 10000 F * With external capacitors 47 F (Electrolytic cap) & 1 F (X7R Ceramic cap) connected to measuring point tech.support psbel.com
