Q: What engineering protection, surge suppression, and environmental tolerances are built into this 6U telecom DC system?

The system carries an IP20 rack-mount rating and features an integrated Class C (Type II) AC surge protection device (In ≥20kA, Imax ≥40kA, 8/20μs waveform) to protect against grid transients and lightning surges. It operates reliably across an ambient temperature envelope of -25°C to +65°C (linear derating above +55°C). The DC distribution section includes high-breaking-capacity circuit breakers (MCBs), dual-route battery inputs, and dual-stage Low Voltage Disconnect (Load LVD and Battery LVD). Rectifiers utilize speed-controlled forced-air cooling, ensuring long-term MTTF even in harsh substation and edge telecom environments.

Question 1

What are the core electrical parameters and efficiency ratings of the DPC 6U Embedded Telecom DC System (SKU: DPC-SYS-6U-EMBEDDED)?

Accepted Answer

The system features a standard 19-inch 6U rack-mount chassis housing up to three DPC 50A high-frequency switch-mode rectifiers, delivering a nominal -48VDC output with a 150A maximum capacity (up to 8.7kW total power). It supports a wide AC input range of 90–290VAC (compatible with single-phase 220VAC and three-phase 380VAC feeds). The DC output voltage is adjustable from -42VDC to -58VDC. Operating with a peak rectifier efficiency exceeding 95.0%, power factor ≥0.99, and THD ≤5%, this system ensures stabilized, high-reliability power delivery for optical transport networks, wireless BBU racks, and FTTx central office gear.

Question 2

How does the DPC 6U DC system handle rectifier slot compatibility, load sharing, and centralized supervisory control?

Accepted Answer

The DPC-SYS-6U-EMBEDDED is engineered with 3 hot-swappable rectifier bays configured for DPC 50A rectifiers, supporting N+1 redundancy and active autonomous load sharing with an unbalance rate <±3%. It integrates a DK04 or DK03 digital LCD monitoring unit, managing smart battery charging, temperature compensation, and Low Voltage Disconnect (LVD) features. For remote telemetry, the controller provides RS232 and RS485 serial ports with optional SNMP network cards, native Modbus support, and telecom standard protocols to enable seamless integration into central OSS systems for live monitoring and remote configuration.
