The SP138/71 is a flexible -48V DC and 230V AC system based on years of experience and expertise in development to meet the customer needs. The system incorporates the energy efficient rectifier and inverter modules, advanced controller, Intelligent load distribution, and batteries.
The 3000 watts rectifiers provide efficiency levels up to 96% and reduce heat and energy loss.  Compact and scalable MEDIA inverters provide a pure supply of AC power. Unlike traditional inverters, the MEDIA features an AC to AC conversion process, that double filters the output wave form assuring high efficiency without any compromise in quality or stability. The system encompasses locations for four hot-pluggable rectifiers and four hot-pluggable inverters.
The system is equipped with an embedded monitoring unit offering all essential functions with battery management functions and even a communication card for remote control through TCP/IP. The communication offers unrivalled functions supporting XML, SNMP, webserver, FTP, all in compliancy with international standards.
Delivered with a temperature sensor, the system features voltage compensation in regard to the battery temperature, protection against deep discharge, battery charge current limitation and regular capacity testing.
The distribution DC section supports up to 40x circuit breakers (1-150A), configured for load or battery breaker, with or without BLVD (battery low voltage disconnect) and LLVD (load low voltage disconnect) depending on site and application requirements. The distribution AC section supports up to 7x circuit breakers (2-63A), configured for load.
