Williams AV CHG 412 – 12-Bay Charger for Digi-Wave 400 Series

Product Overview

The Williams AV CHG 412 is a 12-bay drop-in charger for Digi-Wave 400 Series wireless devices, recharging any mix of DLT 400 transceivers and DLR 400 RCH receivers in approximately five hours. It gives interpretation, guided tour, and wireless intercom systems a central charging station where devices dock without cables or battery removal. For facilities running a Digi-Wave digital communication system day after day, the CHG 412 keeps the full device inventory charged, stored, and accounted for.

Product Description

Each of the 12 bays supplies 5 VDC at 0.5 A, and the drop-in format means staff simply seat a DLT 400 or DLR 400 RCH into a bay after use. Charge status appears on each docked device's own display indicators, so a quick walk past the charging station confirms which units are ready for the next session. The roughly five-hour charge cycle supports same-day turnaround — a meaningful advantage over 16-hour chargers when interpretation systems run morning and afternoon sessions.

The included TFP 066 universal power supply accepts 90-240 VAC and outputs 5 VDC at 6 A. For larger deployments, up to eight CHG 412 chargers (each with its own TFP 066) can operate on a single 15-amp circuit, which simplifies electrical planning in equipment rooms and AV storage closets. The compact 9-inch chassis uses a black ABS enclosure with a metal base for stability on counters and shelves.

Teams that transport systems between venues should consider the CHG 412 PRO with carry case, which adds the CCS 056 transport case. Compatible Digi-Wave transceivers, receivers, and accessories are available in the Williams AV collection.
