Crest factor (Fc) - Ratio between the peak current value to the rms current value.
ISO 9002 - Standard defining procedures and systems used to attain an internationally recognized level of production quality. ISO 9002 certification is proof that the quality system effectively complies with the standard. Certification is carried out by an official organization (AFAQ), unaffiliated with either clients or suppliers or the company itself, and is valid for a three-year period with yearly audits and checks.
Electrical Line Noise - Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) are unwanted electrical signals that produce undesirable effects in sensitive electronic equipment.
Short-Circuit Current (SCC) - The initial value of the current obtained from a battery in a circuit of negligible resistance.
Power Sag - Voltage below 80% to 85% of rated RMS voltage for one or more cycles.
Voltage Depression - An abnormal drop in voltage below expected values during the discharge of a battery.
MTTR (Mean Time To Repair) - Mathematical calculation (or statistical average if available) of the time required to repair a device.
