Multi-bay;drop-in charger w/case for 12 FM

The Williams AV CHG 3512 PRO is a 12-bay drop-in charger for organizing and charging up to 12 body-pack receivers or transmitters in one location. Supplied with a case and a TFP 037 switching AC adapter, it combines centralized charging, individual status indicators, and transport-ready storage. Its 90–240 VAC input supports connection across a broad input range, while the adapter supplies 5 VDC at 4A to the charger.

Ideal Use Cases

This model is suited to systems that regularly deploy multiple rechargeable body-packs and need a consistent process for returning them to service. Its 12-unit capacity allows receivers or transmitters to be placed together instead of relying on separate chargers. This arrangement can be useful wherever a set of body-packs must be collected, charged, stored, and prepared for its next use.

The included case supports applications in which the charging system is transported or stored between sessions. With the charger and case combined, operators have a single system for managing as many as 12 units. The product is specified for use in the United States.

Why Choose This Model

The CHG 3512 PRO addresses the practical requirements of multi-unit body-pack management. Each charging position has an individual red LED indicator, allowing the status of each inserted unit to be observed independently. The LEDs blink when the batteries are charged, providing a direct visual indication without requiring units to be removed and checked separately.

Charging is specified at 140 mA for the 16-hour charge stage and 140 mA for pulse/maintain operation. The nominal charging time is 16 hours. This defined charging cycle makes the model appropriate for planned turnaround schedules where body-packs can remain in the charger between operating periods.

Installation and Integration

Integration centers on the supplied TFP 037 switching AC adapter. The charger accepts a 90–240 VAC power-supply input, and the adapter provides a 5 VDC, 4A output. Once connected to power, the 12 charging positions provide a centralized drop-in location for compatible body-pack receivers or transmitters.

The charger measures 18 inches long by 14 inches wide by 6.75 inches high and weighs 10.7 pounds. These dimensions should be considered when selecting a counter, shelf, storage area, or other placement location. The case has exterior dimensions of 15.7 inches wide by 19.7 inches long by 7.2 inches high. Its interior measures 13 inches wide by 18 inches long by 6.7 inches high, with a 1.5-inch lid inner depth and a 5.2-inch bottom inner depth.

Performance Highlights

• Charges up to 12 body-pack receivers or transmitters at one time.
• Uses individual red LED charging indicators for all positions.
• LEDs blink when the batteries are charged.
• Provides a nominal 16-hour charging time.
• Operates at a 140 mA charging rate with 140 mA pulse/maintain operation.
• Includes a TFP 037 switching AC adapter rated for 5 VDC at 4A output.
• Accepts a 90–240 VAC power-supply input.
• Meets CE, WEEE, and RoHS approvals.

The charger is listed as black ABS. The accompanying copolymer case weighs approximately 6.6 pounds when empty and provides defined interior and exterior measurements for planning storage and transportation.

What Makes It Different

The combination of a 12-bay charging platform and a fitted case distinguishes this model from a collection of individual charging accessories. It consolidates the power connection, charging positions, and status monitoring into one unit. Independent LED indicators retain position-by-position visibility even though the body-packs are managed as a group.

The case adds a second functional layer by keeping the charging hardware together during storage or movement. Its documented lid and bottom depths provide additional detail for evaluating the available interior space. The charger also carries a one-year warranty, while its cables and power supply are warranted for 90 days.

Final Assessment

The Williams AV CHG 3512 PRO is a focused solution for charging and managing up to 12 body-pack receivers or transmitters. Its drop-in format, individual red LED indicators, 16-hour nominal charging cycle, switching power adapter, and included copolymer case provide a clearly specified system for centralized charging and storage.
