3V 12 Unit Charger for R35/R35 -8/RX22-4 R863/T863/T36/R33/R3

The Williams AV CHG 3512 is a drop-in charging station built to handle as many as 12 body-pack-style transmitters and receivers at one time. This US-use model supports the R35, R35-8, RX22-4, R863, T863, T36, R33, and R3 units named for the product. Its black ABS construction, individual red charging indicators, included switching AC adapter, and centralized 12-bay format provide the essential hardware for maintaining a collection of compatible body-packs.

Ideal Use Cases

The CHG 3512 fits workflows that rely on a shared pool of compatible body-packs and need multiple units prepared together. Its 12-unit capacity is useful when transmitters or receivers are handled in batches, returned after use, and placed into a common charging station. Instead of connecting a separate charger to every unit, operators can place as many as a dozen supported devices into one drop-in platform. It can also accommodate systems using different models from the listed R35, R35-8, RX22-4, R863, T863, T36, R33, and R3 product families.

Why Choose This Model

The defining advantage is its combination of 12-device capacity and individual charging indicators. Each position has a red LED, giving operators a visible indication for the corresponding body-pack. The supplied specifications state that the LEDs blink when the batteries are charged. Charging is rated at 140 mA for the 16-hour charge cycle, with a 140 mA pulse/maintain rate. A nominal charging time of 16 hours makes the unit appropriate for planned charging cycles where compatible devices can remain docked between periods of use.

Installation and Integration

The drop-in design keeps setup focused on power and device placement. The charger includes a TFP 037 switching AC adapter rated for 5 VDC at 4A output. Its power supply accepts a 90–240 VAC input, while the supplied product description identifies this charger version for use in the US. Once powered, compatible body-pack transmitters and receivers can be placed into the available bays. The unit measures 9.5 inches long by 7.4 inches wide by 1.7 inches high, or 24.1 by 18.8 by 4.3 centimeters, allowing its physical placement to be planned before integration.

Performance Highlights

The CHG 3512 charges up to 12 supported units simultaneously within one enclosure. Its specified 140 mA charge rate and 16-hour nominal charging period establish clear parameters for scheduling device turnaround. Individual red LEDs provide status visibility across the charger instead of relying on a single shared indicator. The pulse/maintain specification is also rated at 140 mA. The charger weighs 1.2 pounds, or 0.54 kilograms, excluding the power supply, and its black ABS construction provides a unified housing for the charging bays and indicators.

What Makes It Different

This model brings together broad compatibility within the listed Williams AV body-pack range, a dozen charging positions, and status indication for each position. The included TFP 037 power supply means the specified 5 VDC, 4A adapter is provided with the charger. Its published approvals include CE, WEEE, and RoHS. Warranty coverage is one year for the charger, while cables and the power supply are covered for 90 days. These details make its capacity, electrical requirements, charging schedule, and coverage straightforward to evaluate before purchase.

Final Assessment

The Williams AV CHG 3512 is a focused charging solution for users managing multiple compatible body-pack transmitters and receivers. Its main strengths are the 12-unit drop-in capacity, individual red LED indicators, defined 140 mA charging performance, and included switching AC adapter. For installations using the supported R35, R35-8, RX22-4, R863, T863, T36, R33, or R3 models, it provides a single station with clearly documented dimensions, power requirements, charging time, approvals, and warranty terms.
