DC-DC converter 48 V to 12 V 60 W for E60 and E163 batteries

The EB-AC04-01 DC-DC converter is designed to power 12 V equipment from the 48 V batteries in ePropulsion’s E series, such as the E60 and E163 batteries. It provides stable and efficient voltage conversion, essential for integrating standard onboard electronics into a 48 V system.

This converter delivers a nominal voltage of 14 V with a nominal current of 4 A, providing a maximum power of 60 W for your 12 V equipment.

The converter measures 148 x 66 x 56 mm. Its weight is 950 g.

The EB-AC04-01 DC-DC converter has an efficiency of 92%, minimizing energy losses during conversion.

The converter includes multiple protections to ensure safety and reliability:

Overload protection: Operates in constant current mode and automatically restores after abnormal conditions are removed.Overvoltage protection: Shuts off the output and automatically restores after abnormal conditions are removed.Reverse polarity protection: Automatically restores via the internal MOSFET of the power supply after the abnormal load condition is removed, without damage.Undervoltage lockout (UVLO): Output is disabled when input voltage is below 18 V DC.

The converter is designed to operate within a wide temperature range from -40 °C to +85 °C.

The converter is certified CE-EMC, CE-LVD, UKCA-LVD, UKCA-EMC and FCC, ensuring compliance with international standards.

The converter’s input and output cables are each 500 mm long.

The specific model of this converter is the DDR-60L-15.

Yes, it is designed to operate in a relative humidity of 5 to 95% without condensation, making it suitable for marine environments.

This converter is specifically designed to be compatible with ePropulsion E60 and E163 batteries, which are 48 V systems.

The converter accepts a wide DC input voltage range from 18 V to 75 V.

The converter is designed for ePropulsion electric propulsion systems and compatibility is specifically stated with E60 and E163 batteries. For other batteries, it is essential to ensure they provide a stable input voltage within the DC 18-75V range and are compatible with the converter's power and current requirements.

You can power any standard 12 V DC equipment, provided the total consumption of these devices does not exceed the converter’s maximum power of 60 W and rated current of 4 A. This may include lighting systems, VHF radios, GPS units, or other small onboard electronic devices.

To connect the converter to an ePropulsion E60 or E163 battery, you will need the following additional items:

A set of E 150A battery bus bars (E Battery Bus Bar 150A). A set of E battery bridging cables (E Battery Bridging Cable).

Installing the converter requires the following tools:

A Phillips screwdriver. A crimping tool for wires (for 1 to 5 mm² wires).

The packaging of the converter includes the following items:

1 DC-DC converter 48V-12V 60W.4 self-tapping screws M4x16.6 ring terminals RNBL1-6-90D (for wires gauge 22-16 AWG or 0.5-1.5mm²).1 user manual for the DC-DC converter 48V-12V 60W.

The under-voltage lockout function automatically disables the converter output when the input voltage from the battery drops below 18 V DC. This protects both the converter and connected devices by preventing unstable operation or damage due to insufficient supply voltage.

The DC-DC converter’s input wires must be connected to the corresponding polarity terminals on the battery busbar. It is critical to respect positive and negative polarity to ensure correct operation and avoid damaging the device.

The included RNBL1-6-90D crimp terminals are designed for wires with a gauge of 22-16 AWG (American Wire Gauge), which corresponds to a cross-section range of 0.5 to 1.5 mm².
