Why choose this product?
Wide input voltage range and continuously adjustable output voltage
High switching frequency and efficiency suitable for compact installation
Integrated protection functions for more stable operation in real-world applications
Mounting holes and clamps for convenient installation into equipment
Installation and operating instructions
Before connecting, check the polarity of the input and output and set the desired output voltage without load.
For higher loads, ensure sufficient cooling; if the load exceeds approximately 8 A, heat dissipation must be strengthened according to the specification.
Size the supply wires and fuses according to the expected current; minimize voltage drops on the line.
The module is non-isolated the ground (GND) of the input and output is common.
Safety notice
The output voltage can reach up to 50 V DC; observe safe working practices during installation and measurement and avoid short-circuiting the output.
The module is intended for built-in installation (IP20); ensure protection against contact and against the ingress of conductive particles.
Incorrect wiring, insufficient cooling, or overloading can cause overheating and damage to the device.
