What this product is
What this product is
The DPC DZY-48/50H III is an industrial-grade 2900W -48V/50A switch-mode telecom rectifier module designed for BTS and DC plant cabinets. Utilizing full digital DSP control and soft-switching topology, it converts 85V~300V AC utility power into stabilized -48V DC, supporting hot-swap insertion and active autonomous current sharing.
What problem it solves
The DPC DZY-48/50H III rectifier module combines advanced pulse-width modulation (PWM) with zero-voltage switching (ZVS) resonant topology. It delivers a nominal -48V DC output, continuous 50A load capability, and 2900W rated output power with peak conversion efficiency exceeding 95.5%. Integrated power factor correction (PFC) achieves up to 0.99 under fluctuating grid conditions. Engineered for 19-inch telecom sub-racks, the module features a front-to-back intelligent forced-air cooling duct with dynamic thermal speed regulation. The gold-plated rear blind-mate connector enables safe, live hot-swapping. Autonomous analog/digital bus current sharing ensures load unbalance remains under 3% across multi-module parallel architectures without central controller dependency. Comprehensive monitoring is established via isolated RS485 and CAN serial buses, supporting standard industrial monitoring protocols. Protection circuits provide AC over/under-voltage shutdown, DC over-voltage latching, continuous short-circuit protection, and intelligent thermal power derating, ensuring over 300,000 hours MTBF across extreme ambient conditions from -25°C to +70°C.
