Safety Standards & Regulations
|
From XP Power
Most electronic equipment will be tested and approved to the Low Voltage Directive (LVD). This ensures that the unit is safe and allows the manufacturer to fix a CE mark on the product. The LVD is Europe's oldest Directive, it was introduced in 1974 and was upgraded on January 1st 1997. It applies to all electrical products with an intrinsic function and with an input or an output voltage of 50 - 1000 V AC or 75 -1500 V DC. The testing is carried out against Product or Industry Specific Standards; unlike EMC, there are no Generic Standards. There are two types of test. Type testing proves the safety of the product design whilst production testing proves that the product is built correctly. This type of safety testing is usually carried out on all production units. We test to ensure that the product is safe and that there is no risk of electrocution. Products & Services
Power rectifiers are electrical devices that convert alternating current (AC) to direct current (DC). They are an integral part of telecom rectifiers for the telecommunications industry, and in battery chargers, DC power systems, and other power system devices.

Linear power supplies accept AC inputs and provide one or more DC outputs for a wide variety of computer and industrial applications. They use an active element (normally a power transistor) operating in its linear region to generate a desired voltage.
