VF66CH/CH66DC Power Supply
A DC power supply (chopper) is a bi-directional, non-insulated DC/DC converter to meet recent demands for power storage and battery charge-discharge equipment, etc., and Toyo Denki offers a two-model lineup consisting of the VF66CH step-down chopper and CH66 step-up/down chopper.
Features and Functions
Customization Functions Tailored to System (Built-In PLC Functions)
The built-in PLC functions include relay circuits, 36 types of data flow circuit, and 18 types of control block circuit, and the desired type of control can be constructed inside the chopper. (Program capacity: 16 kB, approx. 1,024 steps)
Network Compatibility
Toyo Denki's DC power supplies are compatible with OPCN-1, RS-232C, RS-422, and RS-485 networks, allowing a variety of systems to be constructed through data communication with a host system such as PLC.
Battery Simulator
The VF66CH and CH66 are equipped with a battery simulator mode, allowing the user to set the electrical characteristics of the battery to simulate actual equipment charging and discharging.

DCH66Insulated DC Power Supply
Toyo Denki has developed a DC power supply system combining an insulated chopper and step-up/down chopper.
It eliminates the need for the commercial power supply insulated transformer required for conventional ungrounded system requirements, allowing the size of the system to be reduced.
Features and Functions
Miniaturization of Insulated Transformer by Increasing Frequency
The size of the insulated transformer has been reduced by increasing the insulated chopper switching frequency. The footprint of our existing equipment has been reduced by 60%.
Battery Simulator
The step-up/down chopper is equipped with a battery simulator mode, allowing the user to set the electrical characteristics of batteries or capacitors to simulate actual equipment charging and discharging.
Improved Maintainability
Maintenance workability has been improved with stack structure and cooling fan unit structure, allowing maintenance to be carried out easily. * A dedicated lifter is required for maintenance.
Reduced Maintenance Costs
Long-life parts have been selected for maintenance parts.
(Main circuit capacitor: expected design life of 10 years, cooling fan: expected design life of 5 years)
