: Do not connect the VIN- and VOUT- lines together. Short-circuiting or bridging the input and output ground paths bypasses the onboard low-resistance current shunt resistor, causing the constant current (CC) limiting feature to fail.
: Cuts off output if the input supply voltage drops below the user-defined floor (Configurable range: 4.8V to 36V).
Secure the zk5kx module using the provided M3 mounting holes. Ensure the module is placed on a non-conductive surface to prevent short circuits on the underside of the PCB. zk5kx manual

Shuts off output if load demands cross configured safety levels. : Do not connect the VIN- and VOUT- lines together
One of the ZK-5KX's greatest strengths is its multi-layered software and hardware protection. When a parameter exceeds its set threshold, the output is automatically turned off, and a protection code is displayed on the LCD screen. Press any key to exit the protection interface. The following protections are standard with adjustable thresholds in the system menu:
A solid understanding of the module's boundary limits ensures safe deployment under varied loads: Specification 6.0V – 36.0V DC Do not exceed 36V to prevent terminal damage. Output Voltage 0.6V – 36.0V DC Configurable in increments of 0.01V. Output Current 0.0A – 5.0A Max Resolution down to 0.001A. Output Power Requires active cooling when exceeding 35W/3A. Conversion Efficiency Typical operation at 120kHz switching frequency. Protections Input anti-reverse, Output anti-backflow Safe for direct battery charging.

Over time, or for high-precision applications, you may need to calibrate the ZK-5KX against a trusted multimeter. This procedure should be performed with care.
