Light Emitting Diode
Electronic semiconductor component,
commonly called light diode. Used for optical
signaling.
Simple Network Management Protocol
common protocol in networks to manage /
control appliances
Output Voltage and Frequency Dependent
from mains supply
The UPS output depends of mains voltage
and frequency variations. Former notation:
OFFLINE
Output Voltage Independent from mains supply
The UPS output is independent of mains
voltage and frequency variations. The mains
voltage however is rectified by electronic /
passive voltage regulators. Former notation:
LINE-INTERACTIVE
Output Voltage and Frequency Independent
from mains supply
The UPS output is independent of mains
voltage and frequency variations. Former
