Stolný laboratórny napájací zdroj Voltcraft FSP 1235 — nastaviteľný 11–15 V DC, 35 A

Voltcraft FSP 1235 is a bench laboratory power supply that provides an adjustable DC output between 11 and 15 V with a maximum current of 35 A. The unit is designed for electronics testing, prototyping and repair tasks where a stable low-voltage, high-current source is required. Its compact bench form factor and front-panel controls make it suitable for use in workshops, service centers and research labs that handle power-hungry circuits and components.

Advantages

The power supply delivers a continuously adjustable voltage range from 11 to 15 V and supports sustained output currents up to 35 A, enabling reliable powering of motors, amplifiers and high-current modules. Built-in regulation ensures stable output under varying load conditions, while the front-panel adjustment and clear readouts allow precise setting and monitoring. The robust thermal design and protection features provide safe operation during prolonged use.

Suitable for

• Testing and aligning power stages and motor controllers
• Prototyping high-current circuits and modules
• Repair and service of automotive electronics and audio equipment
• Bench work in electronics workshops and educational laboratories

Key specifications

• Output voltage: adjustable DC 11–15 V
• Maximum output current: 35 A
• Output stability: regulated DC output suitable for testing
• Form factor: bench-top design with front-panel controls
• Cooling: built-in thermal management for continuous operation

How to use

Place the unit on a stable, ventilated bench surface and connect the mains supply according to the local standards. Use the front-panel voltage and current controls to set the desired output; connect the load using suitable cable gauge and secure terminals. Monitor the output voltage and current while applying load; adjust settings gradually to avoid inrush currents that exceed the 35 A limit. If the supply has protection indicators, observe them and switch off the unit before changing connections.

Recommendations

Use appropriately rated cables and connectors to handle up to 35 A continuous current. Allow sufficient ventilation around the unit during extended operation and avoid placing heat-sensitive items on top of the supply. For testing inductive loads or motors, consider adding inrush-limiting measures and monitor current draw to prevent triggering overcurrent protection.
