Power Supply Load Cabinet For Testing Switching Capacity and Durability

2024 08/07

 

Application:

Testing of the switching capacity and normal operating life for switches in household and similar fixed electrical installations.

It also can be applied for Testing the breaking capacity and normal operating life of plugs and sockets .

Test on:

Switches for household and similar fixed electrical installations

Plugs for household and similar use

Sockets/Outlets: "Sockets for household and similar use

Functionality:

A load cabinet is specifically designed to test the performance of electrical equipment by simulating various load conditions.

This allows for the evaluation of the durability and functionality of the equipment.

1.  Operational Control Panel

Ø Panel Surface: The panel features a sandblasted finish to enhance wear resistance.

2.  Control and Display

Ø Power Switch: Controls the main power of the load cabinet.

Ø Display Meters:  Show the current, voltage, power, and power factor of the powered product.

Ø Load Power Switch: Controls the connection and disconnection of the load.

Ø Status Indicator Lights:  Display the operating status of various aspects of the equipment.

Ø Start and Stop Buttons: Used to start and stop the testing process.

Ø Capacitance Selector Switch: Switches between different capacitance values.

Ø Load Type Selector Switch: Switches between different types of loads (resistive, inductive, and capacitive).

Ø Alarm: Sounds an alert in abnormal conditions.

3.  Control Knobs

Ø Voltage Output Adjustment Knob: Adjusts the voltage output for each channel.

Ø Current Adjustment Knob: Adjusts the current for each channel.

Ø Inductance Adjustment Knob: Adjusts the inductance for each channel.

4.  Multifunctional Load

Ø Combined Load Functions:Each load channel has a three-in-one function with resistive, inductive, and capacitive (fluorescent lamp type) loads.

Ø Load Type Switch: Allows switching between different types of loads via a selector switch.

5.  Cooling System

Ø Cooling Method: Internal strong airflow convection cooling effectively prevents overheating and ensures stable operation of the equipment.

6.  Terminal Connections

Ø It is the rear of the load cabinet, allowing connection to a switch and plug socket life tester via wires.  These connections facilitate the output of current, voltage, and power during the testing process.
