YPOWER DC-DC battery chargers
12V, 24v, 36V and 48V models
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 YPO12-24/30).
They also allow a LiFePO4 battery to be recharged from a Lead battery connected to an alternator.
Thanks to their large scale of input and output voltages, they can be configured as a simple converter or as a battery charger.
In this case, the charging curve delivered is comparable to the one of a smart charger:
– 5 steps
– all types of batteries (wet & sealed Lead, Calcium Lead, gel, AGM, Lithium, etc.)
Cooling is done naturally.
Remote control can be done through a serial BUS-CAN interface.

CPS3 AC-DC battery chargers
Our product lines
CPS3 battery chargers
CPS3 battery chargers are no longer in production, except the following model that is still marketed:
48V / 60A- 1 output
CPS3 innovative exclusivities
- Nominal load up to 55°C without any loss
- Specific SP terminal to connect an additional battery isolator for connecting up to 6 independent charging banks.
- 3 year guarantee
Universal AC powering
The AC input voltage and frequency auto-ranging – from 85 to 265 VAC and
from 47 to 65 Hz – guarantees batteries can be charged anywhere (in Europe
and in the USA), from commercial Mains or generators, even when available
power is limited (end of pontoon, foreign network, etc.). Except model 24V/150A 400VAC 3 phases.
Reload 3 battery parks simultaneously
CPS3 battery chargers have 3 independent outputs (except models > 80A) which can individually deliver nominal output current.
One of these outputs is designed for matching specific engine battery requirements for marine application.
The built-in battery isolator on each battery bank means the batteries stay permanently connected to the charger and there is no need to disconnect them during engine startup.
The CRISTEC CPS3 battery chargers are the only ones available on the market with an extra terminal to connect an additional external
battery isolator for connecting up to 6 independent battery banks (3 from the charger and 3 from the battery isolator).
CRISTEC recommends using a voltage drop free isolator. Please refer to the CRISTEC RCE battery isolator range.
Ergonomics
CPS3 battery chargers can be fxed vertically or horizontally.
The charger can be accessed externally by removing the front yellow housing.
AC and DC connections as well as charger settings are grouped together on the PCB in a connection area that ensures a safe, quick and easy installation.
The DC connection on threaded rods is particulary robust and practical due to the available space.
Interfaces
Optional connection for external temperature sensor
- depending on models – enables optimization of battery charging and/or a digital display unit to check battery state


- Tranquility
- Maximum performances
- Reliability
- Flexibility
