The ZXDU48 B600 is a 1U (height) × 19-inch (width) embedded DC power system that can supply power to –48 V series communication devices.

Product Features

Electrical Features

• Supports 220 V single-live wire voltage input and 110 V dual-live wire input.
• Operates in the phase-to-neutral voltage range from 85 V to 295 V.
• Operates in the AC range from 45 Hz to 66 Hz.
• The rated DC output voltage is –53.5 V and continuously adjustable from –42 V to –58

Automatic Sleep / Wake-up of Rectifiers

In power-saving mode, the CSU turns redundant rectifiers to sleep mode or wakes sleep rectifiers up automatically based on the changing load power. The maximum power consumption of a sleep rectifier is 4 W, which saves power greatly.

Monitoring Ports

Provides input/output dry contacts and RS232 ports.

ZXDU48 B600 structure

The ZXDU48 B600 (V5.0R01M01) is 1U (height) × 19-inch (width) power subrack that comprises a PDU unit, a CSU, and ZXD1000 (V5.0) rectifiers.

Dimensions

Components

The CSU520Y is the front-end monitoring module of the DC power system and responsible for tracing and managing the operation of the DC power system.

Management

• Implements discharge management, charge management, and test management on the battery pack.
• Controls the automatic sleep function of the rectifiers and saves power.
• Enables you to view data, set parameters, and control the system through the LCD display and buttons.

Alarm
An alarm is generated and protection is activated if the power system is faulty.

Monitoring
Collects operational data and monitors the operational status of the power system in real time.

ZXD1500 rectifier

The maximum output power of the ZXD1500 is 1600 W. The ZXD1500 converts AC power to DC power for load and battery charging.

Input Properties
The ZXD500 rectifier can adjust its operation status automatically based on the input AC voltage. The input features include input undervoltage protection, input power limitation, and input overvoltage protection.

Input Undervoltage Protection
When the input AC voltage is lower than the configured undervoltage protection threshold, input undervoltage protection is enabled. The rectifier is shut down, there is no output current, and the alarm indicator is lit. When the input voltage increases to the undervoltage restoration threshold, the rectifier automatically resumes operating properly. The undervoltage protection threshold of the ZXD500 rectifier is 80 V ± 5 V, the hysteresis
voltage is 8 V to 12 V, and the undervoltage restoration threshold equals the undervoltage protection threshold plus the hysteresis voltage.

Input Overvoltage Protection
When the input AC voltage is higher than the configured overvoltage protection threshold, input overvoltage protection is enabled. The rectifier is shut down, there is no output current, and the alarm indicator is lit. When the input voltage decreases to the overvoltage restoration threshold, the rectifier automatically resumes operating properly. The overvoltage protection threshold of the ZXD500 rectifier is 305 V± 10V, the hysteresis
voltage is 5 V to 10 V, and the overvoltage restoration threshold equals the overvoltage protection threshold minus the hysteresis voltage

Power Limitation Based on the Input Voltage
The rectifier can limit the output power based on the input voltage.
