Care Labs provides the best ripple voltage testing support in UAE and South Africa for customers security support.
Need to Know About our policy in : TESTING A POWER SUPPLY
One of the most difficult things to do is test the maximum current capability of a power supply.
The easiest thing to do is to connect it to a project and see if it operates correctly, but of you are designing a power supply for general use, you will need to know its capabilities.
There are 4 important features (parameters) need to check:
1. The output voltage
2. The ripple
3. The current capability, and
4. The maximum short-term current.
There are two ways to test a power supply:
1. A Dynamic load – such as an amplifier, computer etc.
2. A Static Load – also called a DUMMY LOAD.
The most common meaning of ripple in electrical science is the small unwanted residual periodic variation of the direct current (DC) output of a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete suppression of the alternating waveform within the power supply. Ripple is commonly measured in millivolts peak to peak (mVp-p) for most ATX computer applications. This is the measurement of the amplitude of the waveform from its highest voltage to its lowest voltage in a given frequency or time period.
We Care Labs Experts Offer Ripple Voltage Testing–
Testing for output ripple voltage and compliance of a Power Supply Unit (PSU)
• The PSU will be powered by the variac and isolation transformer.
• PSU output is plugged into the LB.
• The LB is hard wired to loads.
• In order to find the worst case scenario, PSU input power and output power should be varied through its rated range for all outputs
Care Labs will cover this listed service for best customer supports and needs:
• MEASURING THE OUTPUT VOLTAGE:
• MEASURING THE OUTPUT CURRENT:
• DAMAGING A POWER SUPPLY
• MEASURING THE RIPPLE
• MEASURING THE MAXIMUM SHORT-TERM CURRENT
• CONNECTING A DUMMY LOAD
• PROTECTING A POWER SUPPLY
• FAULT FINDING
