Usina Spark Smart 200A Dual-Voltage Car Audio Power Supply

Adjustable DC power with automatic dual-voltage input

The Usina Spark Smart 200A dual-voltage automotive power supply combines adjustable 12.5–14.4V DC output with an integrated voltmeter. Its listed 200A output is specified at 12.5V under a resistive load, with maximum output power stated as 2,500W.

When preparing your next listening session, monitor output voltage while your installer matches the supply to the connected equipment. Automatic input selection within the supported AC bands provides flexibility for a carefully planned installation.

Ratings are carried over from the existing product specifications. Current and power were measured with a resistive load. Output may vary with mains voltage and operating conditions. Do not assume 200A is available at every output voltage. The AC bands are separate ranges, not a continuous 100–250V range.

Professional Installation and Battery Compatibility

The existing specifications reference 50mm² output cable, a 3 × 2.5mm² grounded input cable and 32A input circuit protection. These are planning references, not a complete installation prescription. Have a qualified installer verify cable sizing, mains capacity, grounding, circuit protection and ventilation against the exact model's manual and local electrical requirements. Confirm protection sizing for the chosen input voltage.

Verify output polarity and connected equipment requirements before operation. Confirm battery chemistry, capacity and supported charging profile before connecting a battery; float mode does not establish compatibility with every battery type.

A voltmeter measures voltage, not current. This unit supplies electrical power rather than amplifying an audio signal. It does not guarantee that batteries will remain charged indefinitely while the sound system operates: connected demand and available output determine the electrical balance.

Included Item and Warranty

The existing listing specifies one Usina Spark Smart 200A dual-voltage automotive power supply and a 12-month warranty. Check the supplied terms for coverage and conditions.
