IntelliSUPPLY Power Supplies

Tuning a system with the engine off, running a demo board or testing amplifiers on the bench all call for steady DC power, which is the role of XS Power IntelliSUPPLY power supplies. The PSC15, PSC30, PSC60 and PSC90 run from wall power and support the system so the battery is not drained while you work.

When a Power Supply Beats a Battery Charger

A charger is built to bring a battery to full charge and then back off. A power supply is built to deliver steady current to a load. During a long tuning session, with the head unit, processor and amplifiers on and the engine off, a supply connected to the system helps hold voltage so settings are made under realistic conditions and the battery is not run down. Retail displays, sound boards and bench testing work the same way, with the supply standing in for the alternator.

Sizing IntelliSUPPLY Power Supplies

Match Output to the Load

The PSC15, PSC30, PSC60 and PSC90 cover a range of output levels, so check each listing for its rated current and voltage settings. Estimate what your equipment draws at the level you plan to run it. A head unit and processor during tuning draw little, while amplifiers at high volume can draw far more than a wall-powered supply delivers; in that case the battery covers the peaks and the supply keeps it topped up.

Voltage Compatibility

Confirm the supply's output suits your battery and equipment, particularly in 14V or 16V systems, where every connected component must be rated for the higher voltage.

Related Charging Gear

IntelliSUPPLY power supplies handle steady power, while storage and recovery after a show are jobs for a dedicated charger: AGM battery chargers for lead-acid banks or lithium battery chargers for lithium. Use properly sized cable and inline protection from our fuses and fuse holders when connecting to a system, and browse amplifiers for demo builds. See every option under chargers.
