FR-A800 Plus Liquid cooled type
Release of the new liquid cooled type inverter, FR-A800-LC
Coolant is used for cooling the inside of the inverter. Liquid cooling enables new applications in the environments where heat is difficult to be dissipated.

Features
- Effective solution for downsizing of the enclosure
A smaller enclosure can be used since the quantity of the heat dissipated in the enclosure is reduced. - Dedicated monitoring functions
A sensor (flow switch) is attached at the inlet of coolant to send a signal to the inverter. When the coolant flow rate decreases, a warning is output, enabling quick, direct detection of system faults. - Lineup of 690 V class inverters
The power supply voltage of 690 VAC is supported. A wider range of power supply voltage is covered.

- The following functions (protocols) are available via general-purpose Ethernet communication.
- CC-Link IE Field Network Basic
- MELSOFT / FA product connection
- SLMP*1
- MODBUS/TCP
- *1SLMP is a common protocol for seamless communication between applications. Users do not have to be concerned with network layers or boundaries.
- *2MELSOFT / FA product connection, SLMP, etc.
What is CC-Link IE Field Network Basic?
CC-Link IE Field Network Basic is a new application of the lineup for CC-Link IE (Ethernet-based integrated network). CC-Link IE enables seamless data transfer between network layers, from higher-order information systems to lower-order field systems, which contributes to the visualization of the production data.
- Cyclic communication (communication speed:100 Mbps)
- Integrated Ethernet network in combination with the TCP or UDP IP connection*2 (no need for dedicated control wiring)
- Simple and inexpensive system construction by general-purpose Ethernet without installing any plug-in option

- Remote monitoring
The FR-A800-E-LC inverter can be remotely operated via Ethernet using FR Configurator2, which will be upgraded soon. Parameter setting, monitoring, and maintenance (for example, parts lifespan diagnosis) of the FR-A800-E-LC inverter is possible through network. Adjustment time and downtime of the inverter can be reduced.
