ZTE RS-59EC-PWR-DC Power Supply Unit

The ZTE RS-59EC-PWR-DC is a high-efficiency DC power supply module specifically engineered for the ZXR10 5900E series of enterprise-class and carrier-grade managed switches. This module serves as the primary power conversion unit, transforming standard DC input voltages into the stable internal voltages required by the switch’s motherboard, interface modules, and cooling systems. It is designed to operate within a wide input range (typically -48V to -60V DC), making it an ideal choice for telecommunication data centers and central office environments where DC power plants are the standard infrastructure.The RS-59EC-PWR-DC incorporates advanced power management circuitry, including over-voltage, over-current, and short-circuit protection, ensuring the longevity and stability of the host chassis. The module features an integrated internal cooling fan and thermal sensors that communicate with the switch's management unit (MCS) to optimize airflow and maintain safe operating temperatures. Its architecture is optimized for high energy conversion efficiency, reducing heat dissipation and operational costs in high-density network deployments.
Designed for maximum network uptime, the RS-59EC-PWR-DC supports a 1+1 redundancy configuration, allowing for seamless failover when two units are installed in the same chassis. The front panel is equipped with standardized LED indicators (PWR, ALM) for real-time monitoring of input status and hardware health. As a critical infrastructure component, it supports hot-swappable installation, enabling the replacement of a faulty power unit without interrupting the data traffic or requiring a system reboot. The module complies with global ETSI, NEBS, and IEEE standards for electromagnetic compatibility and industrial safety.
