VOLTCRAFT CSP-400 AC-labvoeding, instelbaar 1-20 V/AC, 1-2 A, 40 W, net- en batterijvoeding, 1 uitgang VC-17192785

The VOLTCRAFT CSP-400 stands out as a portable AC laboratory power supply that delivers clean, adjustable alternating current from either mains power or its internal battery. Unlike typical DC bench supplies, this unit provides true AC output, making it indispensable for testing AC-powered devices, transformers, and circuits where a stable variable AC source is required. Its compact design and battery operation allow for field use, while the continuously adjustable voltage and current controls offer precise output tuning.

Highlights

• Adjustable AC output: 1–20 V AC, 1–2 A, up to 40 W
• Dual power source: AC mains or built-in rechargeable battery for portable operation
• Single output channel with continuously variable voltage and current
• Ideal for testing AC components, transformers, and low-power AC circuits
• Robust and compact design suitable for lab benches and mobile applications

In daily use

The CSP-400 simplifies AC testing tasks. Set the required voltage and current limits using the front-panel controls, connect your device under test, and monitor the output. When mains power is unavailable, switch to battery mode for uninterrupted operation in the field or at remote test points. The unit's clear labelling and straightforward interface reduce setup time, while its stable output ensures reliable measurements. Whether you are verifying transformer behaviour, powering AC relays, or characterising small AC motors, this supply provides consistent performance.
