Original EPS30-4815AF OLT DC Power Converter System
Dual Wide Voltage Input: Compatible with 110V and 220V global AC grids, the working range reaches 90-290V AC. It operates stably even under unstable power grid, and realizes linear current limiting when the voltage is between 90V and 176V AC.
Dual Current Output Modes: Equipped with 15A and 30A two output specifications. The dual-circuit distribution design (10A + 15A/20A) realizes flexible power supply for multiple loads, adapting to diverse equipment configurations.
High Energy Efficiency & Low Interference: The conversion efficiency is higher than 81% under 110V AC input and over 89% under 220V AC input. The output ripple is less than 200mV, which will not interfere with signal transmission of communication devices.
1U Compact Structure: Standard 1U cabinet size, perfectly matching 19-inch standard cabinets. It occupies little space and is suitable for dense layout of indoor machine rooms and compact equipment cabinets.
Hot-swap & Modular Maintenance: The rectifier module supports hot swap. Modules can be replaced directly without shutting down the system, greatly reducing maintenance downtime and operational risks.
Intelligent Monitoring & Battery Management: Built-in professional monitoring module to real-timely collect operating data. It can be connected with storage batteries and realizes automatic monitoring, charging and protection of battery packs to ensure uninterrupted power supply.
Full-range Safety Protection: Integrated overvoltage, overcurrent, short-circuit and overtemperature protection, as well as excellent lightning protection performance, effectively protecting the power converter and rear-end communication equipment.
Reliable Heat Dissipation: Built-in fan forced air cooling system, stable heat dissipation performance, supporting 24-hour long-term continuous operation.
