Electrical Line Noise - Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) are unwanted electrical signals that produce undesirable effects in sensitive electronic equipment.
Current Drain - The current withdrawn from a battery during discharge.
Bypass (automatic) - In the event of an overload or an unlikely UPS problem, your application is still powered, thanks to the automatic bypass module.
Temperature Cutoff (TCO) - A protective or safety device (e.g., thermostat, PTC, etc.) which senses temperature (e.g., in a battery) and opens or cuts off the electrical circuit if the specified temperature is exceeded, thus preventing a further rise in temperature due to the charge or discharge of a battery.
Working Voltage - The typical voltage or range of voltage of a battery during discharge (also called operating voltage or running voltage).
Fuse - Device used for cutting off an electrical current in the event of an abusive condition.
Gassing - The evolution of gas from one or more of the electrodes in a cell. Gassing commonly results from local action (self-discharge) or from the electrolysis of water in the electrolyte during charging.
