Product Overview
The 150W DC-DC Boost Converter Module is a high-performance step-up power supply designed to efficiently elevate a lower DC voltage to a higher, user-defined level. Engineered with Constant Voltage (CV) and Constant Current (CC) control, this module is perfect for applications requiring a steady voltage source or a precise current limit, such as charging battery packs or driving high-power LEDs.
With a wide input range of 12V to 60V and an adjustable output from 12V to 90V, this converter can support up to 150W of power. Its robust design makes it ideal for solar power systems, electric vehicle auxiliary equipment, industrial automation, and DIY variable bench power supplies. The onboard multi-turn potentiometers allow for precise adjustment of voltage and current, giving you total control over your power delivery.

Usage Guide
Important First-Time Setup
⚠️ Use a Multimeter: The factory default output is often set to a random voltage. Always measure the output with a multimeter before connecting your sensitive load and adjust the CV potentiometer to the exact voltage required.
Wiring Instructions
-
Set Initial Outputs: Before powering on, turn the CV (Voltage) potentiometer counter-clockwise about 10-15 turns to set the minimum voltage.
-
Connect Input: Connect your DC power source (12V-60V) to the IN+ and IN- terminals. Ensure correct polarity.
-
Set Output Voltage (CV Mode): Place a multimeter on the output terminals. Apply input power. Slowly turn the CV potentiometer clockwise until you reach your desired output voltage (e.g., 12.6V for a 3S Li-ion battery).
-
Set Current Limit (CC Mode): This step is crucial for battery charging or LED driving.
-
Connect Load: Turn off input power, connect your permanent load, and re-apply power.
Application Scenarios
-
Lithium Battery Charger: Boost 12V/24V input to the float voltage of a higher-voltage battery pack (e.g., 36V, 48V, 60V, 72V). The CC/CV mode will manage the charge cycle safely.
-
High-Power LED Driver: Provide a constant current directly to high-voltage LED arrays for stage lighting or industrial illumination.
-
Variable Bench Power Supply: Create a versatile lab power supply from a 24V laptop adapter, offering adjustable 12-90V output for testing electronics.
-
Solar/ Wind Power Systems: Boost the variable voltage from a 12V/24V battery bank to a stable 48V/60V/72V bus for inverters or telecom equipment.
Q: What is the difference between Constant Voltage (CV) and Constant Current (CC) mode?
CV mode regulates the voltage at the output, allowing the load to draw as much current as needed (up to the limit). CC mode regulates the current, reducing the output voltage as necessary to keep the current at the set value. This is essential for protecting LEDs from thermal runaway and for correctly charging batteries.
Q: Why can’t I set the current limit by shorting the output?
In a boost converter topology, shorting the output prevents the circuit from establishing the necessary voltage differential to regulate correctly. You must connect a real load (like a battery or a power resistor) when setting the constant current limit for it to work properly.
Q: Does this module have reverse polarity protection?
Yes, this specific module variant includes input reverse polarity protection to prevent damage if you accidentally connect the input power source backward. However, it is still best practice to double-check your wiring before applying power.
Q: How do I calculate the charging current for my battery pack?
The charging current is typically set to 0.5C (half the capacity) for lithium batteries. For example, for a 10Ah battery, set the CC limit to 5A. Always consult your battery’s datasheet for the maximum safe charge rate.
Q: How do I calculate the output power to avoid overloading?
Use the formula: Power = Voltage × Current. The module is rated for a maximum of 150W. For example, if you need 90V output, the maximum safe current is 150W / 90V = 1.66A. Exceeding this may trigger overcurrent protection or damage the module.
Q: Can I use this module to charge a 60V or 72V lithium battery pack from a 12V solar panel?
Yes, absolutely. This is a common application. Set the output voltage to the pack’s float voltage (e.g., 71.4V for a 60V Li-Ion pack) and the current limit to the pack’s recommended charge rate. Ensure the solar panel can supply at least 15A at 12V to provide the necessary input power.
Q: The fan is loud or always running. Is this normal?
Yes. The integrated cooling fan is temperature-controlled. Under heavy load or when the module heats up, the fan will activate to maintain safe operating temperatures. It may run continuously during high-power operation.
Q: My device draws 3A, but the module goes into CC mode immediately. Why?
The current limit setting is too low. Connect an ammeter to the output and increase the CC potentiometer clockwise until the current limit reaches the desired level (e.g., 3A). If it doesn’t increase, the load may be exceeding the maximum 150W power limit.
Q: What is the quiescent (no-load) current consumption?
The module draws a small amount of current (typically 10-30mA) even when no load is connected to power the control circuitry. For battery-powered applications, it’s advisable to disconnect the module when not in use to prevent battery drain.
Q: Can I connect two of these modules in parallel for more power?
Not recommended. Running switching regulators in parallel without dedicated load-sharing circuits can cause one module to supply most of the current, leading to instability and overheating. For higher power requirements, use a single, higher-rated converter.
