JFA Storm 220A Automotive Power Supply & Battery Charger

Manage power for your compatible car-audio setup with the JFA Storm 220A power supply and battery charger. Its illuminated graphical display and rotary control bring operating information and adjustments together in one interface.

Key Features

• Output current listed at up to 220A, subject to the manufacturer's operating conditions.
• Adjustable DC output from 12.5V to 14.5V.
• Automatic dual-range AC input, as specified below.
• Illuminated interactive graphical display.
• Rotary control for navigating settings.
• CCA test, battery equalization and generator modes mentioned in the supplied description; confirm their availability and permitted use on the actual version.

Figures are taken from the supplied listing, not independent test results. Continuous-current rating, derating conditions, mains frequency, input-current requirements and protective functions were not supplied. The two listed AC ranges do not establish support for voltages between 140V and 170V.

Important Version and Battery Compatibility Check

The previous title identifies a Storm Lithium version, while the description names only Storm 220A. Confirm the exact model and supported charging profiles against the actual equipment label and current JFA manual before ordering or connecting a battery.

Do not assume lithium compatibility from the old title or the adjustable voltage range alone. The battery chemistry, cell configuration, voltage limits, charging-current limits and battery-management-system requirements must match the manufacturer's approved profile. Do not use an equalization mode with lithium batteries unless both equipment and battery manufacturers explicitly authorize it for that exact system. A generator mode does not establish compatibility with every generator.

Installation and Electrical Safety

• Have a qualified installer verify the battery, wiring, polarity, fusing, grounding and operating settings using the current manuals.
• Use an electrical circuit, connectors and DC cables correctly rated for the installation. Maximum DC output current is not the same as AC input current.
• Confirm the equipment's input range and frequency on its label before connecting mains power.
• Isolate AC power and follow the manufacturer's battery-disconnection procedure before wiring or servicing.
• Prevent short circuits and reverse polarity. Do not connect damaged batteries or exposed conductors.
• Keep dry, provide the required ventilation and follow the battery manufacturer's precautions concerning heat, charging and flammable gases.
• Do not leave an unverified charging setup operating unattended. Refer internal servicing to qualified personnel.
