PSW7 120V AC Power Inverter Charger – FoxPower

Name: PSW7 120V AC Power Inverter Charger – FoxPower
Brand: Britmar Marine

The PSW7 is a combined inverter, battery charger, and AC auto-transfer switch for residential and light commercial backup power. It delivers 88% conversion efficiency with pure sine wave output, supporting 12–24 VDC input and 120–230 VAC output across 1kW to 5kW power ratings.

MAIN IMAGE

The PSW7 integrates three functions into a single unit: DC-to-AC inversion, battery charging, and automatic AC transfer switching. This configuration eliminates the need for separate components and simplifies installation in backup power systems.

Key operational features include low quiescent current draw, power-saver mode for reduced standby consumption, automatic generator start capability, and surge capacity for high-inrush loads. Status indication via LED display provides real-time system feedback. Optional RS232 communication and LCD display modules are available for remote monitoring and enhanced user interface.

Suitable for emergency backup in residential and small office environments where reliable AC power restoration is required during grid outages.

APPLICATIONS

Primary use cases.

Residential Emergency Backup

Provides automatic AC power restoration for critical household appliances during grid failure, with battery charging capability for continuous operation.

Small Office / Commercial Backup

TECHNICAL FAQ

Common specifications and regulatory inquiries.

What is the primary function of the PSW7?

The PSW7 combines three functions: DC-to-AC power inversion, battery charging, and automatic AC transfer switching. It converts 12–24 VDC battery power to 120–230 VAC output while simultaneously charging the battery from AC mains and automatically switching loads between grid and inverter power.

What does 88% conversion efficiency mean?

88% conversion efficiency indicates that 88% of the input DC power is converted to usable AC output, with 12% lost as heat during the inversion process. This is typical for pure sine wave inverters in this power class.

Can the PSW7 start high-inrush loads?

Yes. The unit includes surge capacity to handle difficult loads with high starting current, such as compressors and motors, beyond its continuous power rating.

What optional features are available?

Optional RS232 communication module enables remote monitoring and control. An optional LCD display provides enhanced status visibility and parameter adjustment beyond the standard LED indicator.

What is the power-saver mode?

Power-saver mode reduces standby consumption by lowering quiescent current draw when the inverter is idle or operating at light loads, extending battery runtime during extended outages.
