VOLTCRAFT CSP-240 Laboratory Power Supply, Adjustable AC Voltage 1 - 15 V/AC, 1.5 A max., 22.5 W, Frequency Control, 1 Output VC-17192765

Where most benchtop supplies stop at fixed-frequency DC, the VOLTCRAFT CSP-240 goes further: it delivers continuously adjustable AC voltage from 1 to 15 V/AC with a variable output frequency of 50–500 Hz. That makes it a compact, single-channel source for testing transformers, motors, audio circuits, and any component that needs a clean, controllable AC signal. The analog meter keeps monitoring straightforward, while the two rotary knobs let you set voltage and frequency independently in seconds.

Highlights

• Adjustable AC output: 1–15 V/AC, up to 1.5 A, 22.5 W maximum
• Variable frequency: 50–500 Hz, continuously tunable
• Single output channel with manual rotary controls
• Analog display for clear voltage and current indication
• Overload and short-circuit protection for safe operation
• Benchtop form factor, ideal for labs and service benches

In daily use

The CSP-240 fits naturally on a crowded workbench. Set the voltage, dial in the frequency, and connect your load — the analog meter gives immediate feedback. Whether you are characterising a small transformer, driving a synchronous motor, or simulating mains-derived signals at non-standard frequencies, the unit responds smoothly and holds its setting. The robust housing and simple layout mean less time reading menus and more time testing.
