Hutton Communications Hutton Communications distributes the newly introduced TeleSol Plus, a standalone power system. It is a fully integrated, pre-assembled package that features Siemens Solar photovoltaic panels augmented by a Libby dc Genset and Deka Unigy II batteries. The models can handle continuous loads from 100W to 400W and intermittent loads of up to 720W. The system will work in the standard configuration anywhere in the United States. The hybrid design is a more efficient and reliable combination than a photovoltaic battery-only system.

Hutton also features the absorbed glass mat (AGM) battery from Deka. This 12V, 100Ah battery is the proven Unigy I battery in a new case that features front-access terminals. This allows the battery to be arranged on shelves with tight space requirements while allowing easy access to both terminals. The battery includes epoxy seals around the terminals that ensure leak-proof operation.

For information, call 972-239-0580.

La Marche The company features power conversion equipment, including controlled ferroresonant and modular high-frequency battery charger eliminators, dc-to-ac inverters and customer dc power systems.

The model A76A is a hot- swappable modular rectifier series and CDP combination and alarm panels. Four hot-swappable modular rectifiers fit across in a 23-inch rack. The CDP combination distribution and alarm panels allow a total of 40 load breakers, up to 100A each and up to eight 200A maximum load breakers. A comparable conventional system (using fer-roresonant technology) would require a large floor-mounted charger plus a rack system for the distribution and alarm panels alone.

Up to four 30A/48V or 60A/24V TPM rectifiers fit across in a cage that only takes up to three rack spaces or two TPM rectifiers with a combination distribution and alarm module.

Power Conversion Products The SSD3 is the newest system status monitor and control that the company offers. Installed in the power systems at remote sites, it monitors rectifiers, converters, battery and power distribution boards, and it provides local and remote status and alarm conditions plus some remote control functions. Locally, status is displayed via a series of digital LEDs and a digital meter. Buttons allow selection of the specific function (mode) to be monitored and displayed.

The PS-19 TwinPack Power System is a modular system designed to provide a variety of power outputs for telecommunications loads. The PS-19 will accommodate single- or dual-rectifier or ringing generator modules. The rectifier module will shut down if the output voltage exceeds a preset value adjustable in 0.5V increments. The rectifier will attempt one auto-restart. If the high-voltage condition still exists, the rectifier will latch off. To restart the rectifier from this condition, recycle the input power.

On standard 48Vdc models, the output current is limited automatically to 12.7A from 0 degrees C to +40 degrees C and 10.5A from +41 degrees C to +50 degrees C ambient. The rectifier is shut down if the ambient temperature sensed at the bottom of the mounting shelf reaches 55 degrees C.

Outputs of -48Vdc, +/-24Vdc, or 12Vdc and 90-105V, 20Hzac (ringing) are available. All modules are connectorized and plug in from the front. The backplane circuit boards accept the entire variety of plug-in modules.

The TwinPack Plus offers six rectifier modules. Higher output (3,000W) rectifiers include the following outputs: -48Vdc for 50A, +24Vdc for 100A and -24Vdc for 100A. Lower output (1,500W) rectifiers include the following outputs: -48Vdc for 25A, +24Vdc for 50A, -24Vdc for 50A and 12Vdc for 100A.

Each rectifier is connectorized to plug into a backplane panel. Rectifier modules can be added or replaced in the field while the plant is fully operational. Rectifiers are connected in a forced load-sharing mode.
