Q & A
What is the output ripple and noise voltage ?The absolute value of the ripple (including noise) of the output voltage at rated output voltage and load current, usually expressed as a peak or rms value.
What is the 50% half-load output voltage ?Full load 50% output voltage.
What is the rated load input power ?Input power refers to the power absorbed by the device. For electrical equipment, the input power is equal to the product of the input voltage to the input current. Input power has different interpretations for different devices. For example, the input power of the speaker refers to the power of the unit inside the speaker that is subjected to the power of the speaker.
What is the rated load input current ?The rated current refers to the current when the electrical equipment is operated at the rated voltage and at the rated power.
What is the rated load output voltage ?It means that the motor is in the best working condition under this data. The rated voltage is fixed with a tolerance of 10%.
What is Unload input power ?Refers to the power consumed by the resistance furnace at the rated temperature without the workpiece being operated.
What is Unload input current ?When the secondary of the transformer is open, there is still a certain current in the primary. This part of the current is called no-load current.
What is Unload output ?The output is not connected to the load.

What is REACH certification?EU regulation REACH certification is "Chemicals Registration, Evaluation, Authorisation
and Restriction" (REGULATION concerning the Registration, Evaluation, Authorization and
Restriction of Chemicals) for short, is the establishment of the European Union, chemical
and since June 1, 2007 implementation product regulatory system.
The new EU chemicals policy, REACH certification (Chemicals Registration, Evaluation
and Authorization), the purpose of a high level of protection of human health and the
environment while promoting innovation and green chemicals.
December 18, 2006 EU regulation (EC) No.1907/2006 registered on chemicals, evaluation,
authorization and restriction, December 18, 2006 the EU Council Directive 2006/121/EC
modified by Commission Directive 67/548/EEC (classification of dangerous substances,
packaging and labeling) on December 30, 2006 published in the official Journal.
REACH will be implemented on June 1, 2007, will replace the nearly 40 existing EU
regulations and directives, to provide a simple system with a better way to manage chemicals.
