DC Power Systems (-48V) - RICEWIND
Featuring a fully digitized DSP architecture, resonant soft-switching topology, and integrated variable-speed forced-air cooling, the M48500N1 achieves exceptional power density and network stability. It supports live hot-swapping and autonomous N+1 active current sharing, ensuring carrier-class durability and zero downtime across demanding outdoor base stations and enterprise telecom environments.
Boasting a peak power conversion efficiency of ≥ 95.0%, this rectifier incorporates full DSP digital control with a wide single-phase AC input range of 85V to 300V AC. It employs an intelligent variable-speed brushless fan for forced air cooling, active load sharing, and live hot-plugging, ensuring low total harmonic distortion (THD), carrier-grade electromagnetic compatibility (EMC), and uninterrupted uptime in harsh grid conditions.
Featuring ultra-high energy efficiency, intelligent digital control, and comprehensive electrical protection, Eltek MINIPACK 48/800 FC delivers uninterrupted 24/7 power and communication stability.
Featuring ultra-high energy efficiency, intelligent digital control, and comprehensive electrical protection, Eltek MINIPACK 48/800 WI delivers uninterrupted 24/7 power and communication stability.
The Vertiv MP2-220K is a microprocessor-based central supervisory controller designed for 220Vdc utility substations and critical power plants. It integrates full rectifier fleet management, busbar-to-ground insulation monitoring, dual AC source ATS automation, battery test profiling, and feeder ground fault location in a rugged industrial panel-mount enclosure.
Featuring a dual-DSP full-digital control architecture and soft-switching LLC resonant converter topology, this module delivers minimal thermal dissipation, superior power density, and reduced acoustic footprint via an intelligent speed-regulated cooling fan. Built for continuous operation in mission-critical environments, it provides hot-plug capability, ultra-low harmonic distortion (THD < 3%), seamless CAN/RS485 bus telemetry integration, and high reliability with an extensive MTBF benchmark.
Featuring a peak efficiency exceeding 93.5%, the NPR48-3G integrates forced air cooling managed by an intelligent variable-speed fan. With advanced Active Power Factor Correction (APFC) and resonant conversion topology, it accepts a wide AC input range from 85V to 300V, supporting active current sharing and live hot-swappability for mission-critical telecommunications infrastructure.
Featuring active power factor correction (APFC) and high-frequency soft-switching resonant topology, the NPR48-ES operates reliably across an ultra-wide AC input range of 85V to 300V AC. Forced air cooling via an intelligent variable-speed fan ensures silent, long-life operation across an extended -25°C to +70°C temperature envelope, while autonomous current sharing and live hot-plugging deliver zero-downtime reliability for mission-critical loads.
