Product Application
TCHR33 series Rack mounted UPS is widely used in government,
finance, communications, education, transportation, meteorology,
radio and television, industrial and commercial taxation, health
care, energy and electricity and other sectors.
Range of Power / Operating Methods
10-25kVA, 3 in 3 out/ 3 in single out, online double conversion
Product Features
TCHR Series online rack-mounted UPS is compatible with three-phase
and single-phase AC output, with rated power of 10-25 kVA, input power factor of 1, 3 U height, and the system - including rectification, inverter,
static bypass, charger, battery converter, control and status
display light unit - all involved with discrete device. Its control
board and sensitive terminals are designed in dust proof, for ease
of use and reliability. It is ideal for modern data centers.
Its fault self-diagnosis and self-protection functions speed up and
simplify maintenance. With auto-switching float chargers, it also
provides RS232/SNMP monitoring ports. Its monitoring software logs
power events, provides a variety of network schemes, and supports
TCP/IP protocols, so as to achieve remote control and management.
- Stability and Reliability
Based on DSP fully-digital control technology, the control circuit
is simplified and obtains higher flexibility and reliability.
Thanks to short circuit, overload, overheating, output over-voltage
protection and current limiting technology, the system runs more
stably. What's more, the power devices gain more space capacity for
more reliable operation.
- Green and Environmental Protection
Built-in EMC filter and dual surge protection makes it safer for
load power, high input power factor reduces grid contamination, and
ROHS compliance is required to meet the high standards of Class B
electromagnetic compatibility.
- High efficiency and Energy Reduction
It provides optimal quality of power distribution and ECO mode
available for reduced energy consumption, with operating efficiency
up to 95% or more. Its smart fan is adjustable in speed in order to
reduce noise and save energy consumption. High power density makes
it possible to cover less space and better improve operation
efficiency.
Rack mounted, suitable for standard server racks, it can easily
integrate with the servers. With user-friendly interface and
6.5-inch LCD touchscreen, it boasts abundant information,
compatible with 3/3 and 3/1 systems.
Output power factor is 1, 15% higher than the common one. It
supports a cold start with batteries to power on in order that an
emergency power is available when needed. Its high input power
factor is more than 0.99.
Very intuitive graphics and a variety of icon images are displayed
distinctively, especially the battery monitoring interface. The
battery capacity histograms show in different colors in response to
the changes of the capacity percentage.
