Mitsubishi FR-F800 Inverter for Pumps and Fans

Mitsubishi FR-F800 inverters are purpose-engineered variable frequency drives for pump and fan applications requiring maximum energy efficiency. The FR-F800 series integrates STO (Safe Torque Off) certified to SIL3 and delivers 150% overload capacity at 60 seconds or 120% continuous overload rating. Flextech Industrial supplies the complete FR-F800 range across Malaysia with commissioning support and genuine Mitsubishi warranty.

Key Features and Performance

Mitsubishi FR-F800 inverters incorporate Optimum Excitation Control (OEC) technology that reduces motor energy consumption by automatically adjusting voltage output to match real-time load conditions. For variable torque loads like centrifugal pumps and supply fans, the FR-F800 achieves energy savings of up to 60% compared to direct-on-line operation.

The FR-F800 series features integrated STO safety function certified to IEC 61508 SIL3 and IEC 62061, eliminating the need for external safety relays in many installations. This built-in functional safety reduces panel wiring, saves cabinet space, and lowers total system cost.

Mitsubishi FR-F800 inverters support dual-rating operation: 150% overload for 60 seconds in heavy-duty mode and 120% overload for continuous fan and pump duty. The drive accepts 200V and 400V three-phase input, covering motor ratings from 0.75 kW to 630 kW across the full product range.

Communication flexibility on the FR-F800 includes a built-in RS485 port and an option slot supporting CC-Link, PROFIBUS-DP, DeviceNet, Ethernet/IP, and Modbus TCP. PID control is built in, allowing the FR-F800 to regulate pressure, flow, or temperature directly without an external controller. A dedicated pump cascade function manages up to eight pumps in parallel operation.

Real-time energy monitoring on the Mitsubishi FR-F800 displays power consumption, cumulative energy use, and estimated cost savings on the keypad or through network communication.

Technical Specifications

Applications in Malaysian Industry

Mitsubishi FR-F800 inverters serve critical infrastructure sectors under Malaysia’s NIMP 2030 modernisation agenda. Water treatment and distribution plants across Malaysia use the FR-F800 to control booster pumps, reducing non-revenue water losses through precise pressure regulation.

HVAC systems in commercial buildings and semiconductor cleanrooms deploy the FR-F800 for air handling unit and chiller pump control. Palm oil refineries and chemical processing plants rely on the FR-F800 for cooling tower fans and process circulation pumps. Municipal wastewater facilities in Malaysia use the FR-F800’s cascade pump function to manage lift station operations with automatic lead-lag rotation.

Mitsubishi FR-F800 vs Alternatives

Mitsubishi FR-F800 inverters succeed the FR-F700 series with significant upgrades in safety, communication, and energy optimisation. Compared to ABB ACS580 drives, the FR-F800 includes STO SIL3 as standard rather than an add-on module. Against Siemens G120P, the FR-F800 offers native CC-Link support critical for Mitsubishi PLC ecosystems common in Malaysian factories. The built-in cascade pump controller eliminates the external PLC logic that Yaskawa GA500 installations require for multi-pump applications.

Frequently Asked Questions

What is the difference between Mitsubishi FR-F800 and FR-F700?

Mitsubishi FR-F800 inverters replace the FR-F700 with added STO SIL3 safety, improved OEC energy saving algorithms, and expanded communication options including Ethernet/IP. The FR-F800 maintains backward compatibility with FR-F700 parameter settings for straightforward migration.

Can the FR-F800 control multiple pumps simultaneously?

The FR-F800 includes a built-in cascade pump controller managing up to eight pumps in parallel. The drive automatically rotates lead and lag pumps based on demand, equalising run hours and providing redundancy without requiring a separate PLC program.

What safety certifications does the FR-F800 inverter carry?

Mitsubishi FR-F800 inverters carry STO certification to IEC 61508 SIL3, IEC 62061 SIL CL3, and ISO 13849-1 PLe. These certifications satisfy machinery safety requirements for pump and fan installations across Malaysia and internationally.

Is the Mitsubishi FR-F800 available for immediate delivery in Malaysia?

Flextech Industrial maintains stock of popular Mitsubishi FR-F800 models in Malaysia. Standard ratings ship within days, while higher-power units may require short lead times. Contact our team to confirm current stock availability for your specific model.

How much energy can the FR-F800 save on pump applications?

Mitsubishi FR-F800 inverters typically reduce pump energy consumption by 30% to 60% depending on the system curve and operating profile. The built-in energy monitor tracks actual savings in kWh and local currency, providing verifiable data for energy audit reporting.
