Introducing the Mitsubishi D800

Mitsubishi micro-drives have been a dependable choice for years. The D700 series of variable frequency drives has been helping with advanced control of motors in a compact package for years. Mitsubishi has leveled up this series by launching the D800 VFD series in the summer of 2025.

The D800 offers many benefits that existed in the previous line and introduces even more features. We’ll cover the new series capabilities, the benefits new to this new generation, and also how to know which D800 is right for you.

Mitsubishi D800 Series Capabilities

Like its predecessor, the Mitsubishi D800 is meant for smaller applications than typical industrial lines. It works for both induction and synchronous (PM) motors and includes the most common voltages for the US market:

A new feature in the D800 line is advanced communication. There are two different lines: standard and ethernet. The standard line includes RS-485 communication with Modbus RTU and Mitsubishi Inverter Protocol. The ethernet line includes single-port ethernet for protocols like Ethernet/IP, Modbus/TCP, CC-Link IE TSN, and CC-Link IE Field Network Basic.

Benefits of the D800

Some of the benefits of the D800 will be familiar, but many are new. In general, Mitsubishi has worked to keep the same great rugged drive while increasing reliability and ease of use. Along with these new benefits, Mitsubishi offers a standard 5-year warranty to back this new series of drive.

Quicker Wiring

The D800 features two new features to help speed up installation. First is that the terminals are now covered by a flip-type front cover, meaning no more screws are necessary to connect your power. They also have transitioned to spring clamp terminals, making it easier than ever to get the drive wired up.

Dual Rating

The D800 is rated for 150% overload for 60 seconds across all voltages, which Mitsubishi refers to as “Normal Duty” or “ND.” For the three-phase drives, they also include a dual rating for “Super Light Duty” (SLD) that is a 110% rating for 60 seconds. This means you have the ratings at your fingertips for lighter duty variable torque applications like fans.

Easy Connection for Programming

Programming is easy through a simple USB Type-C connection from your laptop. No power supply is necessary, that connection alone provides enough power to set parameters right out of the box. This makes it a great option for OEM and high-quantity installations.

Side-by-side Installation

Installations for fan walls, panels, and other similar applications are made easier as the D800 can be installed side by side. These drives are also 63% of the volume of the standard Mitsubishi model. What this means is that you can fit more of these drives in less space with more freedom to configure it how you need.

Built-in Braking

The D800 offers built-in braking transistors on all drives 1/2HP and above. This means you can avoid the cost and space requirements of a separate brake unit.

Upgrading From a Mitsubishi D700

If you’re used to the D700 line, Mitsubishi has made it as simple as possible to upgrade. The part numbers remain similar, the main difference being the introduction of “EPA” to designate the ethernet line. Dimensions are the same for most drives, with a few cases of a reduction in footprint to save space.
