The RT48 Series is a modular embedded switching power system with a total capacity of up to 800A. It integrates the telecom power plant, AC and DC distribution, temperature control and monitoring in one frame, with comprehensive battery management, load and battery low-voltage protection, energy metering, temperature compensation, automatic voltage regulation, current limiting, battery capacity calculation, online battery testing and sleep-mode energy saving.
Design notes
Digitally controlled active power-factor correction keeps input PF above 0.99 and limits harmonic pollution of the grid. Rectifier modules use non-damaging hot-swap technology and can be replaced in under a minute. An ultra-wide input window suits harsh grids and extends battery service life; AC and DC input versions are available. Full battery management includes LVLD + LVBD and a secondary disconnect stage, while both LiFePO4 and VRLA strings are supported. The networked controller offers RS232 / RS485 and dry contacts for flexible remote monitoring and unattended operation, with AC- and DC-side lightning protection, complete fault protection, alarms and a stored event history. All operation and maintenance is from the front, so the cabinet can be placed against a wall.
Configuration
State the present load current and the growth target, the input source, the number of rectifier modules and N+1 spare count, battery chemistry and capacity, distribution breaker layout, LVLD / LVBD setpoints and the monitoring protocol. For a compact fixed 48V system see the RT4860; where only the DC voltage needs changing see the RP DC-DC Converter.
