MD-1000I / MD-2000I / MD-3000I Explanation of USB Function
The advanced in
sulated-gate bipolar transistor (IGBT) technology and indus-
trial quality design ensure the UPS will operate efficiently and dependably,
even under tough conditions.
A powerful CPU integrates all the power stages, control and communication
functions required to provide maximum protection and UPS function, including
monitoring of the energy saving management, remote control and self-
diagnostics. The unit's cleverly designed CPU communication system permits
remote computer control with full functionality from any computer environment
via standard RS-232 port.
The UPS' wide input voltage tolerance (120V~288V) permits under or over
voltage correction without use of the battery, helping to extend the battery's
operating life.
The cold start function ensures the UPS will start even in the event of a power
outage.
A battery management system monitors the battery's charge to determine
when the battery draw will cease, another feature that prolongs the battery's life
span.
Advanced input voltage control minimizes the reactive power factor and in-
creases efficacy. The unit's active power factor correction (PFC) delivers a
power factor (PF) of greater than 0.99, which translates into superb energy ef-
ficiency.
The adjustable bypass input voltage tolerance (low/high) prevents the unit from
switching to the bypass mode in the event of low or over voltage.
Large choices of output voltages (200/208/220/230/240) permit the use of dif-
ferent voltage systems.
This UPS device was designed and built to comply with international electro-
magnetic standards.
