## Description

Smart charger and adjustable CV-CC source for laboratory and service, powered by 220VAC, offers adjustable output 3-60VDC and current up to 8A, maximum power 150W. Includes 5 charging profiles for Li-ion, LiFePO4, HV Li-ion, NiMH and Pb-acid, digital display with real-time values and simple button control. Ideal for testing equipment and safe charging of batteries.
Smart charger and multifunctional programmable power supply capable of a maximum power of 150W, adjustable voltage between 3V and 60V and adjustable current up to 8A, with power supply from the 220VAC network.
The charger has multiple features for charging Li-ion, LiFePO4, HV Li-ion, NiMH and lead-acid batteries, as well as an adjustable CV (Constant Voltage) and CC (Constant Current) power supply function.
It operates in two main modes: intelligent charging mode with 5 selectable profiles for battery types and laboratory power supply mode, with precise voltage and current adjustment. It offers digital display and intuitive control via physical buttons, making it suitable as a replacement power source for various electronic equipment and battery charging.
The output is activated by pressing the ON button. If a battery program is set and there is an error regarding incorrect battery voltage or battery failure, the error message is displayed and the output voltage is interrupted.
The display initially shows the settings, and then, after pressing the ON button, displays the output voltage and current in real time.
Specifications:
Input voltage: 110 - 240VAC
Output voltage: 3V – 60V (adjustable)
Output current: 0.5A – 8A (adjustable), in 0.5A steps
Maximum power: 150W
Battery compatibility: Li-ion / HV Li-ion / LiFePO4 / Pb-acid / NiMH
Protections: polarity reversal, overvoltage, overcurrent, configuration error
Dimensions: 150 × 66 × 45 mm
Use:
Charging mode:
Connect the power supply to the mains (110V/220V, depending on the model purchased).
Select the battery type by pressing the "Mode" button.
Adjust the voltage to the appropriate battery using the "Voltage + / –" buttons.
Set the charging current (recommended 0.5C or according to battery specification).
Press "OK" to start charging. The red LED lights up during charging.
When fully charged, the message "-FULL-" is displayed and charging stops automatically.
Note : If the battery is connected in reverse, the red and green LEDs will flash simultaneously and charging will not be performed. For lead-acid batteries, if a wrong voltage is selected, the device will display “-ERR-” and will not charge.
The current setting is adjustable in 0.5A. The power supply is capable of delivering up to 150W. When setting the battery charge, if it does not allow a higher voltage setting, it is because you have set a current that is too high (VxC>150W). Set a lower current so that the output is below 150W.
Feeder mode:
Turn on the device without any load connected.
Adjust the desired voltage and current.
Make sure that the connected load does not exceed 70% of the maximum power of the power supply.
Press "OK" to turn on the power.
