DC-DC BATTERY CHARGERS Wide Input/Output scale T° performance Silent THERMAL CHARACTERISTICS YPOWER DC-DC chargers-converters have been designed to charge a 12, 24, 36 or 48V battery bank from a 12, 24, 36 or 48V network. The most typical case of use is the 24V bow-thruster battery bank charge from the 12V onboard network (model YPO1224/30). They also allow a LiFePO4 battery to be recharged from a Lead battery connected to an alternator. • Operating temperature : from -20° to +60°C without derating • Storage temperature : from -40° to +70°C • Optional temperature probe : compensation -18mV/C° in 12V, -36mV/C° in 24V, -54mV/C° in 36V and -72mV/C° in 48V Thanks to their large scale of input and output voltage, they can be configured as a simple converter or as a battery charger. In this case, the charging curve delivered is the same as the one of a smart charger : - 5 steps - all types of batteries (wet & sealed Lead, Calcium Lead, gel, AGM, Lithium, etc.) INPUT/OUTPUT CHARACTERISTICS • Input voltage : 12 or 24 or 36 or 48VDC (from 10 to 64VDC or from 10 to 45VDC according to models) • Output voltage : 12 or 24 or 36 or 48VDC • Nominal power : from 570 to 860W (depending on model) • Max. output current : from 10 to 60A at nominal voltage (depending on model) • Isolation Input/Output : no as 0V is common • 5-step charging curve : Boost, Absorption, Floating, Refresh & Reboost • Battery type selection through push-button or communication • Efficiency : 96% typical • Ripple : < 2% (at nominal conditions) • Electronic limitation of the input current • Remote control : serial CAN-BUS interface PROTECTIONS - PCB : water-repellent varnish (marine environment) Output : * Integrated anti-return device to avoid battery discharge * Protection against polarity reversal by removable fuses Input and output : current limitation and automatic power limitation for an ambiant temperature > 60°C MECHANICAL CHARACTERISTICS • Dimensions (l x h x d) : 236 x 180 x 96 mm - Weight : 2.2kg • Protection : IP22 • Input/output connection : with M6 terminals • Indicator : 2 bicolour LEDs • Casing : 4 x M5 external fixings for easy wall mounting • Natural cooling (fanless)
