Precision Switched Power Supply

A high-performance power supply designed for the demands of the modern school laboratory.

Combining an excellent electrical specification with a compact, practical design, the Lascells Precision Power Supply delivers up to 8 A of regulated DC output, available in either switched or continuously variable models.

Its key advantage is its regulated DC output, maintaining the selected voltage regardless of the load connected. Add an adjustable maximum voltage limiter, automatic over-current protection and a digital voltage display, and you have a powerful, dependable and easy-to-use power supply, designed with both teachers and students in mind.

With additional 6 V and 12 V AC outputs, a robust steel case and a truly space-saving design, the Lascells Precision Power Supply offers outstanding performance in a compact package, taking up minimal space wherever it is used or stored.

Key features:

• Regulated DC output: Provides a constant, regulated DC voltage regardless of the load connected. Simply select the required voltage and check the reading on the built-in digital panel meter. The supply maintains the displayed voltage throughout the experiment.
• Adjustable maximum voltage limiter: Allows teachers and technicians to set a maximum output voltage using an Allen key through the front panel. Students can then adjust the main voltage control as normal, but cannot exceed the preset limit. A simple, practical way to restrict the voltage available during experiments.
• Digital voltage display: A clear, built-in digital panel meter continuously displays the DC output voltage, making it easy to monitor and set the required voltage.
• Automatic over-current protection: If the output current exceeds 8 A, the supply automatically reduces the output voltage to zero. Normal operation is restored as soon as the current demand falls, with no manual resetting required.
• Additional AC outputs: Separate, unregulated 6 V and 12 V AC outputs, rated at up to 1.5 A, provide additional flexibility for AC experiments, including transformer investigations. These outputs can be used alongside the DC output.
• Switched or variable output: Available in two versions: continuously variable DC or switched DC output. Both offer the same high-quality electrical performance and facilities, allowing you to choose the configuration that best suits your teaching requirements.
• Compact, space-saving design: The power supply is lightweight, easy to carry and simple to store. Four units fit neatly into a single Gratnells storage tray.
• Robust construction: Housed in a durable, powder-coated steel case with an integral plastic carry handle and removable mains lead, designed for the demands of everyday laboratory use.
• Simple, intuitive controls: Clear, straightforward front-panel controls and an illuminated mains switch make operation easy for both students and teachers.
