Product Overview
The 600W DC-DC Boost Converter is a high-power, professional-grade step-up voltage regulator engineered for demanding applications requiring significant power conversion. With an adjustable input range of 10V–60V and an output adjustable from 12V–80V (or up to 90V) , this module delivers exceptional flexibility for boosting lower voltage sources to higher levels .
This non-isolated boost converter features Constant Voltage (CV) and Constant Current (CC) control, making it ideal for lithium battery charging, LED driving, and powering industrial equipment . Independent multi-turn potentiometers allow precise adjustment of both output voltage and current limit, giving you complete control over your power delivery.
With a compact footprint (approximately 85×62mm) and integrated heatsink, this module is designed for efficient thermal management. It achieves conversion efficiencies of up to 95% , minimizing power loss and heat generation .

Additional Features
⚠️ Critical Safety Notes:
-
This module has NO input reverse polarity protection – connecting input backward will damage the module
-
The module cannot regulate output voltage below input voltage (boost only)
-
The fuse may run hot under load – ensure good airflow
Usage Guide
Important First-Time Setup
⚠️ Use a Multimeter: The factory default output is often set to a random voltage (typically 19V) . Always measure the output with a multimeter before connecting your load and adjust the CV potentiometer to the exact voltage required.
Wiring Instructions
-
Select Input Range: Use the onboard jumper to select appropriate input range – 8-16V for 12V battery applications, or 12-60V for wide-range input .
-
Set Initial Outputs: Before powering on, turn both potentiometers counter-clockwise about 10-15 turns to set minimum.
-
Connect Input: Connect your DC power source to the IN+ and IN- terminals. Ensure correct polarity (no reverse protection). Add a series diode for protection if needed .
-
Set Output Voltage (CV Mode): Place a multimeter on output terminals. Apply input power. Slowly turn CV potentiometer clockwise until reaching desired voltage.
-
Set Current Limit (CC Mode) :
-
Connect your actual load (LED array or discharged battery)
-
Slowly turn CC potentiometer clockwise while monitoring the ammeter
-
Stop when reaching desired current
-
Note: This module cannot regulate current down to 0A; it has a minimum current that drifts
-
Connect Permanent Load: Power on the module first, then connect the load – especially important for high-power loads .
Thermal Management & Power Derating
The maximum output power depends on the input/output voltage differential and cooling:
Important: This module struggles at low input voltages (near 12V) under high load without forced air cooling . Always use active cooling for loads >10A.
Cooling Fan Setup
The DC barrel jack can be repurposed to power a 12V or 24V cooling fan :
-
12V fan: Spins at nominal speed with 12V input; may run faster at higher voltages
-
24V fan: Provides good cooling across 12-35V input range (spins slower at 12V)
-
Mounting: No dedicated fan mounting points – you’ll need to design a bracket or lean a fan against the heatsink
Typical Applications
Q: How much real power can this module actually deliver?
The module is rated for 600W, but this depends on input/output voltage differential. Effective power = input voltage × 10A . For example, 12V input × 10A = 120W effective. To achieve full 600W, you need at least 40V input (600W ÷ 15A = 40V). The module draws up to 15A input current
Q: Why does my 12V system struggle to deliver high power?
This module does not perform well at 12V input under high load without a cooling fan . At 12V input, it’s limited to approximately 10-12A input current (120-144W input power). For 48V output applications, start with a 24V-36V input for better performance .
Q: Can this module regulate current down to 0A?
No. This module cannot regulate current down to zero – it has a minimum current that drifts . This is important for applications requiring very low currents, such as trickle charging.
Q: How do I set up current limiting for battery charging?
Set the voltage to the battery’s float voltage, then adjust the current limit while connected to a discharged battery. The module has output anti-reverse protection, so no external diode is needed for charging applications .
Q: Do I need a cooling fan for this module?
For loads under 200W, passive cooling may suffice. For loads above 200W or with input below 24V, a cooling fan is highly recommended . The DC barrel jack can be used to power the fan .
Q: Why does the module have two power inputs?
The screw terminal is for main power input. The DC barrel jack serves as an alternative input but is best used as a convenient 12V fan power connector . This allows the fan to run directly from the input source.
Q: What happens if I exceed the input current limit?
The module has overcurrent protection that automatically reduces output voltage when input current exceeds approximately 17A . The 20A fuse provides additional short circuit protection .
Q: Can I use this module to power LED lights directly?
Yes, using constant current (CC) mode. However, note that some LED types may not work well with pulsed DC output . Test with your specific LEDs before permanent installation. For LED applications, set CC mode to the LED’s rated current.
Q: Is the output voltage isolated from the input?
No. This is a non-isolated boost converter – input ground and output ground are common . Do not use for applications requiring galvanic isolation.
Q: What safety features does this module include?
The module includes:
-
Output anti-reverse protection (for battery charging)
-
Overcurrent protection (reduces output at ~17A input)
-
Short circuit protection (20A fuse)
-
No input reverse polarity protection – add external diode
