Main Features |
|
|
Full digitized microprocessor controlled improves UPS reliability |
|
|
Use single chip microprocessor, PWM based for inverter output pure sine wave with synchronous phase-lock loop, LI series can make the protection of over voltage,overload over temperature speedy and accurate. High speed microprocessor control the inverter and simply the circuit, improve the agility and stability of UPS control. |
|
|
Auto-bypass |
|
|
When LI-RM/INV.fails, the inverter can transfer to Mains automatically. |
|
|
19 inch rack-mount UPS power |
|
|
19inch/3U rack-mount equipments are widely used in the internet servers, telecom field, manufacturing fields. LI-RM19inch series are in accordance with international standard for structure design. |
|
|
Communications and network management |
|
|
The availability of RS-232 communication make it possible for UPS to realize its multi-functional and multipurpose monitoring management by connecting the computers and other surveillance equipments. include:mains status,UPS working status,system setup,menu operation, remoted control and self-diagnostic,record and anylysis,system shut down etc. The network management system can also be set up by optionalSNMP slot. |
