Bungalow & Remote Site Power System
The Bungalow and Remote Site Power System (RRSPS) series provides a DC power solution that integrates quickly with batteries, loads, and transmitters. Available in 12, 24 or 48 volt configurations, the compact 300 watt assembly contains: power supply with temperature compensated battery charger; and programmable alarm contacts, all in a rugged, vibration hardened compact case. Versatile installation options include wall mount, 19" rackmount, and DIN-Rail. Extreme operating temperature rating with convection cooling make the unit ideal for rail wayside bungalows, remote site shelters, pole mount enclosure applications, as well as private network base stations and microwave sites.
Features
- Well regulated noise free 300 watt output - maintains batteries with no interference to sensitive electronic loads
- Charger output regulated by temperature compensation sensor with high voltage limit under extreme low temperatures (meets AREMA standards)
- Low voltage disconnect option protects batteries from extreme discharge (feature activated by wiring configuration)
- Output current indicator LEDs
- Wide temperature operating range (-40 to +70° C) with convection cooling - no fans to service, meets AREMA standards
- High input/output isolation ratings meet AREMA standards
- Alarm contacts interface with remote monitor systems
- Active load sharing allows wiring in N+1 configuration for redundancy and/or in parallel for higher current capacity
- Hardened for high vibration enviroments in wayside applications
- Optional Rack and DIN-Rail mounting bracket
