Sure Electronics Co., Ltd. has implemented strict test for Constant Voltage Amplifiers


Sure Electronics specially designs complete audio amplifier and power supply solutions - CVA Series for constant voltage applications, such as public address announcement system, background music system, fire alarm system, school broadcast system and so on.

When comes to constant voltage systems, reliability is a paramount considering factor. It is quite important that the constant voltage amplifiers and the power supply have the ability to continuously operate with high reliability and stability.

Keeping this requirement deeply in mind, Sure Electronics has implemented comprehensive tests for constant voltage amplifiers before shipment to verify its ruggedness and ensure the products customers get can work stably.

Sure Electronics implements the following test items for CVA series:

1. Maximum output power test

The DUT (Device Under Test) must be able to deliver rated power at any time, no matter working under a constant voltage mode or a constant resistance mode.

2. Extreme... read all

STRONG ENOUGH, To survive in the most harsh environments.

SMALL ENOUGH, To make each space most effective.

SURE Electronics will be transformed into a professional designer and a manufacturer of Class-D audio amplifiers and matched power supplies. So SURE brand will fade away from retail and Sure Electronics will be committed to provide solutions, instead of direct products, for our distributors and partners. Our company name, Sure Electronics, will always remain the same.
