Havis TS12-400 Vanner TS Series Pure Sine Wave Power Inverter 12VDC Input 400W AC Output

The Havis Vanner TS12-400 is a 400-watt pure sine wave power inverter engineered for commercial vehicles, public safety fleets, and mobile workforces that demand clean, reliable AC power in the most demanding conditions. Designed by Vanner — a trusted name in commercial vehicle power conversion since 1977 — this DC-to-AC inverter converts 12V DC battery power into stable 120V AC output suitable for powering sensitive electronics, tools, and equipment.

Featuring Vanner's proprietary TruWave technology, the TS12-400 generates true pure sine wave AC power that is safe for even the most sensitive electronic devices, including laptops, medical equipment, and precision instruments. Unlike modified sine wave inverters, the TruWave output eliminates electrical noise and interference, protecting your equipment from damage.

Key Features:

• 400W continuous AC output with 3-second surge capability to start and run demanding tools and equipment
• TruWave pure sine wave output for clean, stable power compatible with the most sensitive electronics
• 90%–93% efficiency rating for extended engine-off run time and reduced battery drain
• Wide DC input range of 10.5Vdc to 16.5Vdc — compatible with all OEM multi-voltage and multi-mode alternators
• Operating temperature range of -20°C to +40°C (-4°F to +104°F) for reliable performance in any climate
• Low-profile all-metal housing with integrated mounting features for in-cab and behind-the-seat installation
• Advanced microprocessor-controlled design with built-in protection against overload, overheating, and short circuits
• Flexible mounting orientation — secure installation regardless of position

The TS12-400 is part of Havis's Vanner TS Series lineup, a range of rugged DC-AC inverters built specifically for professional mobile applications including law enforcement, emergency services, utility fleets, and commercial transportation. The compact, low-profile form factor makes it ideal for space-constrained installations without sacrificing performance or protection.
