Medium Current Smart Power Distribution Unit PDU

Medium Current Smart Power Distribution Unit PDU

 

A smart power distribution unit (PDU), also known as intelligent PDU, goes beyond distributing power to IT equipment within the data center. It is capable of monitoring, managing, and controlling power consumption to multiple devices. The smart PDU provides data center professionals with remote network access to real-time critical infrastructure data to help drive informed decision making to ensure maximum availability and to meet important efficiency requirements. While there are two main types of smart PDUs, monitored and switched, each type has a variety of additional features that can be included to increase the critical information available from the device. Some of the key features include outlet level monitoring, environmental monitoring, alerts and alarms based on user-defined thresholds, and many more. These features minimize downtime and carry manufacturer-provided support to meet Service-Level Agreements (SLAs).

In the middle of the power distribution unit is the operation indicator area, which contains operation and fault status indicators. The operation indicator lights after power-on. When a fault occurs, the fault indicator lights.

 

 

The input pin characteristics are as follows:

l  IN1: digital input port (high effective), frequency acquisition frequency (10~20KHz)

l  IN2~IN11: digital input port (high and low effective), switch quantity acquisition, voltage quantity acquisition (0-5V)

l  IN12~IN15: Digital input port (low effective), switch quantity acquisition, voltage quantity acquisition (0-5V)

 

The output pin characteristics are as follows:

l   A variety of current outputs, with 4 PWM outputs;

l   Contains one output port of wiper circuit (CON4-E), conventional load is 6A output, and the maximum power of wiper motor is 180W;

l   OUT9~ OUT12 are configurable for high/low side drive;

l   The output pin is controlled by a high-side switch, which can be directly used in the complex and harsh automotive electronic environment, and HSD integrates a complete diagnostic function, which can be set intelligently with the application software to improve the safety and reliability of the system , Service life, while reducing system cost, completely replace the traditional fuse + relay combination.

l   The work flow of the high-side switch is as follows:

 

l   The output pins of this product adopt high-side switches of 30A, 15A and 9A.

l   30A high-side switch: rated output 30A; output current can be configured within the rated output range. After the current exceeds the configured value, the output is turned off after a period of time (configurable within 1ms~65s).

l   15A high-side switch: rated output 15A; the output current can be configured within the rated output range. After the current exceeds the configured value, the output is turned off after a period of time (configurable within 1ms~65s).

l   9A high-side switch: rated output 9A; output current can be configured within the rated output range. After the current exceeds the configured value, the output is turned off after a period of time (configurable within 1ms~65s).

Installation Notes：

 

1. When designing the installation location of the power distribution box, please install it as close to the battery as possible to reduce the length of the harness

2. The power distribution box is fixed to the side wall of the electric cabin through the four fixing holes on the periphery, and is fixed by M6 steel bolts, plus flat pads and spring pads, and the torque is 15NM

3. Please purchase the plug-in corresponding to the harness end of the power distribution box from regular manufacturers to avoid assembly difficulties caused by counterfeiting errors
