Description
NSR250F Series – Battery Charger / Power Supply – 250W, 12Vdc / 24Vdc / 48Vdc
The NSR250F Series is a compact industrial-grade battery charger and DC power supply platform engineered to provide stable DC power and intelligent battery charging for critical infrastructure applications. Delivering up to 250W of continuous output power, the NSR250F supports both precision regulated DC supply operation and advanced battery charging functionality.
Available in 12Vdc, 24Vdc and 48Vdc variants, the NSR250F combines programmable temperature-compensated charging, battery integrity monitoring and configurable output voltage control into a highly reliable industrial platform. Unlike UPS variants, the NSR250F is optimised for charger and DC supply applications without integrated no-break battery transfer functionality.
All models include standard RS-485 MODBUS RTU communications for integration into SCADA and industrial monitoring systems. Ethernet/SNMP-optioned models add web-based monitoring and remote configuration capabilities, providing full visibility of charger status, alarms and operating parameters.
The NSR250F features wide-range AC input, rugged mechanical construction and fan-assisted cooling for dependable operation in industrial and utility environments. Compact dimensions and Phoenix terminal outputs simplify installation into space-constrained control cabinets and remote enclosures.
