The ZK-5KX CNC DC-DC Buck Boost Converter is a highly versatile and budget-friendly power module that serves as an excellent foundation for a DIY lab power supply or battery charger. Performance & Specifications

This module is an upgraded version of the popular ZK-4KX, offering more power and active cooling.

Understanding Your ZK-5KX: A Complete User Guide The ZK-5KX is a popular CNC DC-DC buck-boost converter module. It’s a favorite among DIY electronics hobbyists because it’s versatile, relatively cheap, and features a clear LCD display. Whether you’re building a custom laboratory power supply or charging batteries, this manual covers everything you need to know. 1. Technical Specifications

Before wiring it up, ensure your project falls within these operational limits: Input Voltage: 6.0V – 36V DC Output Voltage: 0.6V – 36V DC Output Current: 0 – 5.0A (Max)

Output Power: 80W (Natural cooling); up to 120W with enhanced cooling/heatsink. Voltage Resolution: 0.01V Current Resolution: 0.001A Efficiency: Approximately 88% 2. Physical Layout & Interface

The ZK-5KX features a digital encoder (the knob) and two buttons: U/I (Upper) and SET (Lower).

LCD Display: Shows input/output voltage (V), current (A), power (W), capacity (Ah), and running time (h). Terminals:

IN+/IN-: Connect your power source here (e.g., a laptop power brick or battery). OUT+/OUT-: Connect your load or device here. 3. Basic Operations How to Set Voltage and Current

Short press the "U/I" button: This enters the setting interface. You will see the voltage or current digits flashing. Turn the Rotary Encoder: Increase or decrease the value.

Short press the Encoder Knob: This moves the cursor to change which decimal place you are adjusting (great for quick jumps from 0.1V to 1V). Short press "U/I" again: Save and exit the setting mode. Switching the Display Data

While on the main screen, short press the SET button to cycle through: Output Power (W) Capacity (Ah) Energy (Wh) Running Time (h) 4. Advanced Settings (The System Menu)

To enter the deep configuration menu, long press the "SET" button (about 2 seconds). The Go to product viewer dialog for this item

LVP (Low Voltage Protection): Set the minimum input voltage. If the input drops below this, the module shuts off to protect your source battery.

OVP (Over Voltage Protection): Set the maximum output voltage limit.

OCP (Over Current Protection): Set the maximum output current limit. OPP (Over Power Protection): Set the maximum wattage.

OAH/OHP: Set maximum capacity or time limits (useful for timed battery charging). To save and exit: Long press "SET" again. 5. Safety Features & Protections The ZK-5KX is equipped with several software protections:

Reverse Polarity Protection: Protects the board if the input is wired backward.

Anti-Backflow: Generally safe for battery charging, though using an external diode is always safer for high-capacity batteries to prevent current flowing back into the module when powered off.

OTP (Over Temperature Protection): The module will automatically shut down if the onboard sensor detects excessive heat. 6. Common Usage Tips

Calibrating: If you notice the voltage readout is slightly off compared to your multimeter, you can enter the calibration mode by holding "U/I" and "SET" simultaneously during power-up (refer to specific firmware versions for slight variations).

Heat Management: If you plan on pulling more than 4A or 80W consistently, add a small 12V fan or a larger heatsink to the back of the board.

Input vs. Output: Remember that this is a buck-boost converter. It can step 12V up to 24V or down to 5V. However, the input current will be significantly higher than the output current when stepping voltage up. Troubleshooting

"ERR" Display: Usually indicates a protection trigger (OVP/OCP). Check your limits in the SET menu.

No Output: Ensure the "ON/OFF" indicator is active. Short press the encoder knob to toggle the output on and off.

The ZK-5KX is a popular DC-DC buck-boost converter—a handy little tool used by hobbyists to build DIY power supplies or charge batteries. It essentially takes an input voltage (like a laptop power brick) and lets you precisely "dial in" the output you need.

Below is a quick functional guide based on the ZK-5KX User Manual, followed by a short story about its "life" in a workshop. Quick Manual & Key Features

Specs: Input 6–36V, Output 0.6–36V. It can push up to 5A or 80W. The Interface:

U/I Button: Tap once to set Voltage, tap again to set Current Limit (the "CC" mode).

Rotary Knob: Turn to change values. Press the knob to move the cursor (jump from 0.1V to 1V increments).

SW Button: Cycles through the bottom display line: Power (W), Capacity (Ah), and Run Time.

Protection: It has built-in safety for over-voltage (OVP), over-current (OCP), and even a timer to stop charging after a set duration. A Story: The Heart of the Workbench Optical Sensor: Utilizes a robust optical fingerprint sensor

In a cluttered garage filled with the scent of solder and ozone, the ZK-5KX sat nestled inside a 3D-printed case. It wasn’t the biggest tool on the bench, but it was the most important. To the old laptop power brick hidden under the table, the ZK-5KX was a translator—taking raw, messy energy and turning it into something useful.

One morning, its owner, a hobbyist named Elias, brought in a dead cordless drill. Its battery was so drained the "smart" charger refused to even recognize it. Elias tapped the U/I button on the ZK-5KX. The display flashed 12.00V. He turned the knob until it hit 14.4V, then limited the current to 1.000A to keep things safe.

As Elias connected the leads, the ZK-5KX’s red CC (Constant Current) LED flickered to life. The tiny fan on its radiator spun up, a quiet whir against the silence of the garage. On the screen, Elias watched the Ah (Ampere-hours) counter slowly climb—a digital heartbeat showing exactly how much life was being pumped back into the battery.

Hours later, the ZK-5KX hit its programmed time limit. With a soft click of its internal logic, it cut the power, saving the battery from overcharging. Elias returned, saw the "End" message on the screen, and smiled. He’d saved the drill for the cost of a $10 module and a bit of patience. The ZK-5KX went back to idle, its blue backlight glowing, ready for the next project. zk-5kx_voltage-converter.pdf - eleneasy.com

The ZK-5KX is a CNC DC-DC Buck-Boost Converter capable of handling up to 5A and 80W. It allows you to both increase (boost) and decrease (buck) input voltages between 6.0V and 36V to a stable output of 0.6V to 36V. Basic Operation Guide

Switching Display Information: Short press the SW button to toggle the bottom line between Current (A), Power (W), Capacity (Ah), and Time (h). Setting Output Voltage: Short press the U/I button while on the main screen. Rotate the encoder knob to change the value.

Press the knob to move between digits for faster adjustment. Short press U/I again to save and exit. Setting Current Limit (CC):

While in the voltage display mode, press U/I twice to enter current setting.

Adjust the limit using the knob. The CC LED will light up when the output reaches this set limit.

Power Toggle: Short press the encoder knob to turn the output ON/OFF. Advanced Protection Settings

To enter the protection menu, long press U/I (approx. 2 seconds) while on any main screen. Use SW to cycle through these parameters: LVP: Low Voltage Protection (Input undervoltage). OVP: Over Voltage Protection (Output overvoltage). OCP: Over Current Protection. OPP: Over Power Protection. OHP: Overtime Protection (auto-off after set time). OAP: Over-capacity Protection (auto-off after set Ah). Key Technical Specifications Range/Value Input Voltage 6.0V – 36V Output Voltage 0.6V – 36V Output Current 0 – 5.0A Output Power 80W Max (requires cooling for sustained high loads) Safety Features Input anti-reverse, Output anti-backflow, OTP (Over-temp)

Critical Tip: Never short-circuit the Input (IN-) and Output (OUT-) terminals; doing so will bypass and disable the constant current (CC) functionality.
