TX90 6kVA & 10kVA User's Manual
Product Introduction
General Characteristics
• True online architecture continuously supplies your critical device with stable, regulated, transient-free,
pure-sine-wave AC power.
• 20 kHz PWM sine-wave topology yields excellent overall performance. The high crest factor of the inverter
handles all high-inrush current loads without a need to upgrade the power rating.
• The multi-functional LCD/LED panel displays various states of the UPS. The LED display shows the UPS
working status, utility status and abnormal status. The LCD display shows input/output voltage, frequency,
load status, inner cabinet temperature, and abnormal phenomena.
• To protect the unit from overloading, it automatically switches to bypass mode in 160 seconds at 100-
105% load, or 40ms if loading is at 105 ~150% of rating. In case of overloading at 150% of rating, it switches
to bypass mode immediately. It will automatically switch back to inverter mode once the overload condi-
tion ceases.
• Should the output become short-circuited, the UPS cuts the output automatically until the short-circuit
situation is removed manually.
• Should the unit become overheated, the internal thermal switch will detect the heat and switch to bypass
mode and vice versa.
• The fully digitalized control circuit built into the UPS allows upgrading the functionality of the UPS as well
as reaching a high-level of protection of the UPS. Powerful communication capability enhances its ability
for remote control and monitoring.
• Maintenance-free, sealed batteries minimize after-sales service.
• The maintenance bypass switch provides an easy and safe troubleshooting or maintenance function when
the utility is normal.
• Providing four different working modes (Normal, ECO, CF50 and CF60) it may be used in a wide variety of
applications.
• The DC-start function ensures the start-up of the UPS during power outages.
• A revolutionary battery management circuit analyzes battery discharging status to adjust the battery cut-
off point and extend battery life.
• The intelligent, temperature-controlled fan may not only extend the life of the fan but also reduce noise
because of sudden fan spin. This helps keep your office quiet and comfortable.
• When the UPS is out of order you can read the possible reason directly from the LCD screen, which re-
duces unnecessary repairs.
• When the UPS is operated in CF50 or CF60 mode, the recommended load connected shall be 75% of rated
capacity if the input voltage is 176-280 VAC and 50% of rated capacity if the input voltage is 160-280 VAC.
