Automated people movers (APMs) utilize rubber tires and a guided path.
APMs are typically completely automated, but there are some that are manually operated.
Toyo Denki’s first real APM installation was the Nanko Port Town Line operated
by the Osaka Municipal Transportation Bureau in 1961.
Our APMs use either 3-phase AC with converter/inverter control or DC withvariable voltage variable frequency (VVVF) inverter control.

NormalAuxiliary Power Supply
High voltage power input from the overhead catenary or the third rail typicallyhas a wide range of voltage fluctuation. The auxiliary power supply (APS)
converts this power to a stable, low-voltage power supply for such uses as air
conditioning and lighting in the train. It keeps providing stable power even when
there is voltage fluctuation on the supply or load side. Our product lineup covers
a wide range of performance needs in terms of capacity, mounting location,etc. Our APS inverters and converters maintain a strong reputation among ourcustomers for their superior reliability, maintainability and energy efficiency.

Features■ Two-level and three-level inverters that utilize a reduced power loss, high voltage IGBT.
Compact, lightweight, simple main circuit configuration for high level of reliability.
■ We also have a lineup of high-frequency DC/DC link method series for high-speed trains,
LRVs and APM applications that especially require compact, lightweight solutions.
■ Wide variety of specifications to accommodate selection of cooling method (natural coolingor forced-air cooling) and enclosure shape variations (long enclosure, integrated enclosure),
based on application, mounting location and mounting space, etc.
■ We also can supply parallel synchronous and standby redundancy solutions for single
equipment applications if a high level of reliability is required in particular.

We currently supply a wide range of current
collectors, the single arm type for EMUs,
in particular, but also those for the Shinkansen
high-speed trains, suburban trains, LRVs, various
types of APMs and electric locomotives. We maintain a high reputation among our customers forthe superior compactness, minimum maintenance and low aerodynamic noise of our products.

Features■ For high-speed trains such as the Shinkansen, the framework is sleekly covered, only one
shoe is used, and holes are made on the main horn to suppress aerodynamic noise.
■ For EMUs, we have reduced the number of parts compared to that of conventional diamondtype pantographs and made it endurable against falling snow, more compact and lighter.

These devices enable output from the train
operator’s commands, such as forward, reverse, powering,neutral and braking, to the electric train’s control device, etc.
Our product lineup covers a wide range of methods, including the one handle with brake valvefunction and a controller that detects the main handle position without contact.

Features■ Since this is a very critical device for the train operator, we have thoroughly implemented consideration
for safety and reliability into the design. Thanks to our many years of experience, our master controllers
maintain a strong reputation among our customers for their superior operability and reliability.
■ We can accommodate the needs of a variety of systems. For example, we also manufacture
converter units that convert the output signal from the master controller to each type of signal for
application to control transmission systems, which have been increasing in recent years.

Train Control Management Systems
In 1983, Toyo Denki became the first company to develop a train-monitoring device using optical fiber.
At the time, monitoring functions were limited to detecting and recording failures in onboard equipment.
Since then, however, we have moved into having some control functions for sending control commandsignals, and nowadays we are making our system with faster, higher -capacity streamlined controls forcommunication within the train using highly reliable train communication technology. By improving thesystem’s functionality, we are bettering train operability, maintenance and passenger service.

Features ■ Compatible with the next version of Train Communication Network (TCN) International Standard IEC61375■ The train communication network uses Ethernet Consist Network (ECN) for a ring network withbuilt-in redundancy.
■ The subsystems such as the train control system, passenger information display system (PIDS) anddoor operation control system can be integrated and connected via the network for complete control
over all the devices in the train.
■ Devices using conventional interfaces (digital, analog I/O or RS485) connect to the ring network via
the remote I/O device.
■ Network topology can be selected from such options as redundant, single, tree, ring and star, basedon the importance of the applied subsystems.

High Speed Circuit Breaker with Deionizing-Grids
Unit Switch with Deionizing-Grids
Advantages of High Speed Circuit Breaker

Advantages of Unit Switch■ The arc does not scatter from the arc chutedue to electromagnetic closing system.

■ Superior breaking ability and quiet breaking.
■ The arc does not scatter from the enclosuredue to electromagnetic closing system.

■ For convenient maintenance, the breaker canbe set upright, or be laid horizontal with the arc
chute facing up.

■ The breaker can be fit without any insulator
since the enclosure is insulated with FRP.

Train Event Recorders
In Japan a number of years ago, there was a train accident that occurred due to a train rounding a bendin the track at an excessive speed. This led to a revision of technical standards and to the mandatory
installation of recording devices to log data in the event of an accident. In response, we did morethan simply develop a device for analyzing the state of operation during an accident; we went beyond
by developing and commercializing multifaceted products that, for example, can assess the state ofoperation for rolling stock with no monitoring equipment.

Features The analysis software is easy to use for train business operators;

production configuration is suited to installation in existing rolling stock.
Also, thanks to the integration our many years of achievement in trainelectronics, we have succeeded in producing a highly reliable, highly
satisfactory system for the train business operators who use our products.

Door Operating Equipment
This system is used to open and close the side doors and cabin doors of electric and diesel trains.
Our door operating equipment maintains a strong reputation among our customers for its superior
compactness, light weight and low required maintenance. We have optional accessories such as
conductor switches and one-man vehicle open/close switches. We also provide portable slope devices
for closing the gap between the platform and door to make it easier for wheelchair users to get on andoff the train.

Features ■ Available types: Lintel mounting type; double-door interaction type, and single-side opening type

■ We also have a platform door controller device system and a control device for weakening theclosing force of the door for a set amount of time in the event that a passenger’s clothing article or
belonging gets caught in the door.

■ Operation can be powered by either a pneumatic cylinder or electric cylinder.
