1.1. The General Characteristics
• True On-Line architecture continuously supplies your critical device with
a stable, regulated, transient-free, pure sine wave AC Power.
• 50KHz PWM sine wave topology yields an excellent overall performance.
• The high crest factor of the inverter handles all high-inrush current loads
without a need to upgrade the power rating.
• To protect the unit from overloading, it automatically switches to Bypass
mode in case loading exceeds 120% of rating. It will automatically
switch back to On-Line mode once overload condition is removed.
• Should the unit become overheated, the internal thermistor will detect
the heat and switch to the Bypass mode and vice versa.
• Maintenance-free sealed-type battery minimizes service.
1.2. The Advanced Technical Characteristics
• Market leading light and compact design.
• Powerful CPU integrates all power stages, control and communication
functions necessary for maximized UPS protection and functionality,
including Power management status monitoring, configuration setting,
operation scheduling, remote control and self-diagnosis.
• Advanced CPU communication design allows full function remote
control from any computer environment via the standard RS232
interface.
• State-of-the-Art IGBT Technology and Industrial Grade quality ensures
the highest efficiency and reliability under the worst operating condition.
• Industry leading inverter protection technology incorporates 2-stage
output Current sensor, smart overload output current control, improved
crest factor, and feedback fail proof circuit.
• Guarantees an exclusive protection against DC damage for inductive
load, such as motor-based devices.
• Advanced Input PFC control guarantees the PF performance and
maximum energy efficiency.
• Unique electronic over-current protection detects output short-circuit and
faults, and halts the output before damages are done to the output fuse
or the equipment.
• Expanded input voltage range minimizes battery usage and maximizes
battery life.
• Automatic Frequency Sensor reduces the frequency shift.
• DC-start function allows the UPS to operate when there is no input
power available.
• On-demand self-diagnosis function ensures UPS reliability.
• SNMP adapter slot allows power management and diagnostics via the
Internet from any where in the world.
• User adjustable output voltages for your critical equipment.
