Since the 1960s, Meidensha Corporation (“MEIDEN”) has developed chopper control equipment for battery-operated forklift trucks and related motors. In recent year, MEIDEN was among the first to offer the products necessary for such Motor-powered vehicles going AC and has many supply records.Draiving on its "advanced motor control technology" resources as proven by the top market share of such products, we will continue to offer you our safe, secure, and high-quality Economical Controller.

HelpingMotor-powered VehiclesGoing AC

We have many supply records of motor controllers for battery-operated forklift trucks. For more than ten years, we have supplied AC motors and controllers for forklift trucks in japan markets. We are keeping the top share in sales in Japan markets. (Note) Products of forklift truck makers are excluded.

Considering rigorous operating environ-ments, we placed the reliability as top design factor. Each product went through various evaluation tests taking into account of the applicable condi-tions. We provide the high reliability products.

In addition to standard products, we have know-hows to meet for various customizing needs of the customers and we parsue the best product experi-ences for the customers.

The AC400 Series involves the latest AC motor controllers featuring compact design and high efficiency. Two types, Type S and Type L, are available, and you can chose according to capacity.

AC400 SeriesController

Type S Type L

Type S Type LAC400 Series / Product Outlines●This is a high-efficiency AC controller to be used for motor-powered vehicles such as electric forklift trucks using low-loss MOS FETs . ●With increased IEC international Protection (IP) level, this equipment can easily be incorporated in motor-powerd vehicles. ● There are four series. Two types of current capacities (small/large capacity) and two types of battery voltages (48V/72V) are available. It provides wider application range, ranging from small to large motor-powerd vehicles.

Compact design:

Self-diagnostic feature:

Can customize

This equipment is still compatible with Meidensha conventional products (Type S) in terms mount-ing design. Yet, the volumetric size is reduced to about 75% of conventional model.

This product is provided with a self-diagnostic function. With the aid of an on-board LED display, error indications can be given without using any other special diagnostic tools. Diagnostic data can also be transmitted through the CAN line. The following items can be checked by the self-diagnostic function.

If requirement characteristics of voltage, capacity, etc., are within the specification range, and by tuning this product can flexibly work with motors made by other suppliers. It best works with Meiden motors and it could provide the best performance.

This is a motor controller applicable to general-purpose industrial vehicles. The standard setting is made for IM (induction motor) control. With optional setting, it can work with PM (permanent magnet) motors.
