Huawei W0PSA1701 Power Module Product Overview

Huawei W0PSA1701 Power Module is 170 W AC Power Module for S6720S-26Q-EI-24S-AC, S6720S-26Q-EI-24S-DC

The rapid development of the communication industry has greatly promoted the development of communication power supplies. High-frequency miniaturized switching power supply and its technology have become the mainstream of modern communication power supply systems. In the communication field, the rectifier is usually called the primary power supply, and the DC-DC (DC-DC) converter is called the secondary power supply.

The function of the primary power supply is to transform a single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V. Currently in the primary power supply used in program-controlled switches, the traditional phase-controlled regulated power supply has been replaced by a high-frequency switching power supply. The high-frequency switching power supply (also known as a switching rectifier SMR) works through the high frequency of MOSFET or IGBT, and the switching frequency It is generally controlled within the range of 50-100kHz to achieve high efficiency and miniaturization. In recent years, the power capacity of switching rectifiers has continued to expand, and the capacity of a single unit has expanded from 48V/12.5A, 48V/20A to 48V/200A, 48V/400A.

Huawei W0PSA1701 Power Module Product Features

• Input protection

Input overcurrent and undervoltage protection is provided.

• Output protection

Output overvoltage and short-circuit protection is provided.

• Alarm function

Various alarms such as the alarm triggered when there is no power input and the alarm triggered when there is no power output are supported.

• Overtemperature protection

When the temperature of the power module exceeds a specified threshold (75°C), the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.
