1.74kW 1U 19 inch Ultra-Compact DC Power System for Telecommunication Infrastructure

Product Overview of 1U Ultra-Compact DC Power System

The 1U 1.74kW DC power system delivers regulated -48V DC output in an ultra-compact 1U chassis, purpose-built for small cell deployments, micro-sites, and space-constrained communication applications. Featuring a single MR4830N rectifier module with >93% efficiency, this system offers an ideal balance of performance, cost-effectiveness, and physical density. Its pre-configured design simplifies deployment, allowing operators to rapidly scale network capacity without extensive on-site engineering.

Controller of 1U Ultra-Compact DC Power System

The controller provides extensive I/O functionality: 3 analog inputs (dedicated to 2 battery temperature sensors and 1 ambient temperature probe), 2 RS485 communication ports, 7 digital inputs for external status monitoring, and 6 dry-contact alarm outputs for integration with site alarm systems. Communication flexibility is a key strength, with support for Ethernet, SNMP, ModBus, and RS485 protocols, enabling seamless integration into diverse network management platforms and allowing operators to choose the monitoring interface that best fits their existing infrastructure. This multi-protocol capability ensures the system can be deployed in greenfield sites as well as legacy environments without compatibility concerns.

Power of 1U Ultra-Compact DC Power System

This system is specifically pre-configured for small cell applications, where physical footprint, capital expenditure, and operational efficiency are critical success factors. The 1U form factor maximizes rack density, enabling more equipment per cabinet and reducing site rental costs. The rectifier module's >93% efficiency directly translates to lower energy consumption and reduced cooling requirements, contributing to a lower total cost of ownership over the system's lifecycle. The AC input is protected by a 16A/2P compact MCB and a 20kA/40kA surge protection device, while the DC side provides 3 output terminals for load distribution and a dedicated 50A battery terminal for backup connectivity. Comprehensive protection against over-voltage, under-voltage, over-current, and over-temperature conditions ensures system reliability even in challenging operational environments.
