广州EMERSON艾默生GXT4-6000RT230U不停电电源
Liebert? GXT3? UPS Includes These Outstanding Features:
Flexibility:
yyRack/tower configuration. The
versatile unit installs in either
configuration, and includes a rotating
LED display panel that conforms to
the desired orientation.
yyAutomatic frequency detection.
Detects and matches line input
frequencies of either 60 or 50 Hz.
yyUser replaceable hot-swappable
internal batteries. Provide four
minutes of runtime at full load.
yyAdditional runtime with additional
battery cabinets. UPS cabinet
includes rear panel plug-and-play
connections for optional battery
cabinets. Cabinet sizes: 5-6kVA – 2U,
8-10kVA – 4U, 6kVA 208V– 3U.
yyLiebert IntelliSlot? communications
port. Utilizes Liebert IntelliSlot Web
Card to provide SNMP and web-based
monitoring and control of your UPS.
yyIncludes Windows-based
configuration program. Allows
various operating parameters to be
adjusted and tests to be scheduled.
yyBuilt-in USB communications
for use with Liebert MultiLink?
Automated Shutdown
Software. Allows you to monitor
communication between the UPS
and a server, and ensures a graceful
unattended shutdown.
yyBuilt-in closure signals. Provides
notification to monitoring systems of
operating conditions including: on
battery, low battery, battery mode
shutdown and any mode shutdown.
yyEmergency Power Off (EPO).
Terminal connections for a normally
open or normally closed emergency
power off switch.
Higher Availability:
yyWider input voltage window
minimizes battery use. Features a
wide input voltage window that allows
the UPS to support the critical load
without hing to transfer to battery,
extending system ailability for when
battery back-up is truly needed.
yyInternal automatic and manual
bypass. Assures continuity of
power to critical loads during
system maintenance or in case
of internal fault.广州
yySelf-diagnostics. Automatically
tests unit electronics and batteries.
Designed to simplify maintenance
and troubleshooting.
Lowest Total Cost Of Ownership:
yyStandard two-year replacement
warranty. No-hassle warranty
provides paid shipping both ways.
Optional one-year and three year
extensions ailable.
yyUses less rack space. Lees more
room for network equipment.
yyFor longer service life.
Shields batteries from heat
generating electronic components,
enhancing battery life.
yyBattery cutoff voltage. Automatically
adjusts based on load, extending
battery life by divventing
over-discharge of batteries.
yyENERGY STAR? qualified UPS
models. UPS products meeting the
EPA’s requirements
use an erage of
35% less energy
than their standard
counterparts.
上述因素的影响也因塑料材料的不同，或者其它成型条件如温度、湿度、继续结晶化、成型后的注塑机的变化而不同。由于注塑过程是把塑料从固态(粉料或粒料)向液态(熔体)又向固态(制品)转变的过程。从粒料到熔体，再由熔体到制品，中间要经过温度场、流场以及密度场等的作用。在这些场的共同作用下，不同的塑料(热固性或热塑性、结晶性或非结晶性、增强型或非增强型等)具有不同的聚合物结构形态和流变性能。凡是影响到上述因素必将会影响到塑料制品的物理力学性能、尺寸、形状、精度与外观质量。
