Voltage converter 8.5-48V to 10-50V DC, max. 8A, 250W

Non-isolated DC/DC boost (step-up) converter for increasing and stabilizing DC voltage in applications with variable input. The output voltage is continuously adjustable using a trimmer, the module is designed for integration into devices and power supply from DC sources (e.g. batteries, power lines, industrial DC distribution).

Functions and features

• Continuous adjustment of output voltage using a trimmer
• Suitable for increasing voltage while maintaining DC power supply without galvanic isolation
• Integrated protections for common fault conditions (overcurrent, short circuit, reverse polarity)
• For higher currents, it is necessary to ensure adequate heat dissipation (cooling)

Ideal for

• Powering devices requiring higher DC voltage than the source provides (e.g. 12 V to 24 V / 36 V / 48 V)
• Built-in power supplies in industrial electronics, automation and laboratory assemblies
• Power supply from battery systems and DC distribution within the permitted range

Package contents

• DC/DC converter (boost) – 1 pc.

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.
