Integrated Power Systems

“All-In-One-Package” Powers National Service Network

The Integrated Power Systems supply DC power and battery back-up to numerous critical networks. A recent installation required high reliability 12 VDC for land mobile radio base stations for the National Park Service in Utah.
The 2-way radio system consists of a network of base stations and repeaters. Due to the extremely remote areas, most sites operate on stand-alone solar power providing necessary power to the locations’ buildings including visitor’s center and employee residences and radio systems. For the locations with utility AC power, it is unreliable and very harsh to sensitive electronic equipment such as repeaters, wireless broadband point-to-point microwaves and other critical communication devices. Because of the rough conditions, the National Park Service wanted to keep all of the sites’ critical communication system’s power similar, streamlined and simple. Thus the Integrated Power System was chosen.

The Integrated Power System (IPS), model IPS-12-40, provides 12 VDC directly to the base station’s Motorola radios and to the Daniel Electronic repeaters, which are also supplied with utility AC power. Each site is also configured with a bank of external batteries that will utilize the charging circuit of the IPS to provide extended battery back-up.

The unique multifunction “integrated” power supply is ideal for remote critical sites. The IPS contains a power supply and built-in batteries for battery back-up. It also features additional rear battery terminals, which are utilized to tie in additional battery strings for longer ride through during AC power failure. The batteries are always ‘in-line’ with the load, thus there is no interruption from relays or transfer switches in the event of AC loss. Batteries are recharged when AC power is restored. A manual battery disconnect switch allows internal or external battery service or replacement while the system is running. Also, the Integrated Power System features an automatic low voltage disconnect to prevent damage to the powered equipment and to protect the batteries from permanent capacity reduction because of a low voltage input.

The Integrated Power Systems, which occupies only 2U (3.5”) (2RU) of vertical rack space, also features output metering, LED status, and Form C failure alarm contacts. All are pre-wired and calibrated within the unit for plug-and-play operation. The rear plug-in terminals also make the wiring easy for an additional parallel rectifier input. Also, they feature numerous protection features such as AC input breaker, internal battery breaker, auto thermal shutdown/recovery, current-limiting, short-circuit and over-voltage protection, to guard sensitive electronic equipment like wireless broadband radios, point-to-point microwaves, repeaters, routers, and other critical communication equipment.

The Integrated Power System is also available in 24 VDC and 48 VDC outputs in power ratings of 11-22 amps.
