Power supplies provide reverse polarity

Designed for base-station installation, the PS15A and the PS20A from Geiger Communications are power supplies equipped with reverse polarity and short-circuit protection to minimize risk due to improper installation or use. These products incorporate switching technology and also allow operation on either 110Vac or 220Vac. The PS15ABB and PS20ABB offer a battery charger and switching circuitry to automatically revert to battery mode if the ac power is interrupted, with no interruptions in vital communications networks. With the optional hoods, any mobile can be converted to a reliable base station.

Converter eliminates need for filtering devices

The BTCPower SQ series from Broadband TelCom Power features a metal-shielded, low-profile, 100W quarter brick designed to prevent EMI and thus eliminating the need for ferrite beads or other EMI/RFI filtering devices. This shield also acts as a heat dissipating medium with large surface area, therefore eliminating the need for heat sink or forced air-cooling. Delivering 20A with efficiency (90%@5V), this model is useful for the high-energy power needs of the telecommunications industry.

System incorporates power accessories

Newmar's Integrated Power System incorporates built-in battery backup, power accessories and auxiliary power inputs within a single 2RU (3.5") chassis. This eliminates the need for system integration, component sourcing and installation. A regulated power supply/charger, backup battery, low-voltage battery disconnect and output metering are all pre-wired and calibrated within the unit for plug-and-play operation. Plug-in terminals are provided for easy wiring of a parallel rectifier, or external batteries for increased backup capacity.
