AU Series

2.2kw high power model is now available! AU: high performance high voltage power supplies - Low profile rack mount

High Voltage Power Supplies(Rack Mount/Bench Top) AU Series

Best & Long Seller of Rack-mount type HV power supplies! Maximum 2.2kW output power in this ultra low profile design

AU series is a high performance, high-reliability and high-quality DC high voltage power supply as a result of our high-voltage power technology built up over the years. High efficiency and ultra miniaturization is realized with our switching and voltage isolation technology.

With wide lineup of over 300 models and various options the best suitable model for your application can be selected from the output range of 1kV to 120kV / 30W to 2.2kW. AU series has various remote control and monitor functions as standard, and by adding digital control interface it will contribute to the extensibility for ATE (Automatic Test Equipment) system as well as to various high-voltage experiments and to evaluations of inverters and power devices. AU series is only a third to a half size of conventional power supplies and dedicated to compactness of device and saving space of facilities. Double and triple protections are added for even safer operation. With new master-slave option higher power output operation is now possible.

Wide range of lineup

The best output range and function from abundance of lineup of 1kV to 120kV/30W to 2.2kW, over 300 models can be selected. Therefore no need to choose a product with over output or specifications avoiding wasted investment.
AU series has -LC option for automatic switch of constant voltage/constant current modes as well as other various options such as different input voltage or slow ramp up are available.

Full of remote function

High-voltage output voltage and output current (output cut off value for standard type, and current limit value for AU with -LC option) can be controlled. Also equipped with output ON/OFF, monitor output for voltage/current and status output of high voltage is equipped and door switch is standard as a safety function.
Also interface of GPIB, RS-232C, RS-485 and USB can be added as an option for computer control.
A system integrartion with other measuring instruments or control devices can be constructed for faster testing and development. It’s easy to build a system up with the combination of our DC (low voltage) power supplies or AC power supplies.

Ultra low profile / space saving

Panel height is only 1.73” (models less than 1kV to 60kV/30W to 300W models) and 19-inch standard rack mount type. Miniaturization and high reliability that are conflicting themes for high-voltage power supplies are cleared by our high voltage insulation technology.
AU series has been receiving good reputation for applications requires space saving such as inspection system of production line, or requires combination several power supplies.

HV Power Supplies AU Series Input/Output cable


HV Power Supplies AU Series Functions
HV Power Supplies AU Series Remote control connector


-LStc: Constant Curreent status signal

Constant Current mode or when OCP (Over Current Protection)
activated, the open collector will turn on. (Vce > 2V)

-LStv: Constant Voltage status signal

When operation mode is Constant Voltage mode,the open collector will turn on.(Vce > 2V)

-LC :Constant voltage and constant current*2

Current regulation 0.05%
(-LC option eliminates Overload Trip function)

-LF: Floating ground (withstanding voltage of 50Vdc) *1

Used when measuring minimal current in load.
All equipments that connect to Remote Control Connector (TB1) must be on floating ground in case this feature is intended to use.
(Cannot be used for the purpose of floating high-voltage power supply.)

-LMs: Master slave control (600W, 1.2kW and 2.2kW models only) *1*2*3

Maximum of 4 slave units can be controlled with one master unit.

-LW: Slow start*1

Takes about 10 seconds to reach a set voltage from when OUTPUT switch, remote switch and remote switch are turned on.

-L (220V)

200VAC to 240VAC single phase input. (30W to 300W models only)

-L (115V)

100VAC to 120VAC single phase input. (600W models only)

-L (U)

Input voltage switch over 100VAC to 120VAC/200VAC to 240VAC single phase input.
Internal switch over. (30W to 300W models only)

-L (200V3P)

three-phase input (2200W models only)

-L (3m)

The length of HV output shielded cable is changed to 3m.

-L (5m)

The length of HV output shielded cable is changed to 5m. (only for 40kV models)

-L (7m)

The length of HV output shielded cable is changed to 7m. (only for 15kV models)

-LPs: Setting value display

The set voltage value and the set current value are displayed on the meter,while you pressing the SET button on the front panel.
(This button is attached only when -LPs option is chosen.)

*1 In case selecting -LMs option with -LF option or -LW option, all AU power supplies which connected as Master-Slave, need to equip -LF option or -LW option.

*2 In case power supply operate as cut off the output when overcurrent with Master-Slave connection, do not select -LC option for Master unit(the other options can be selected), and select -LC option for only Slave unit (the other options can be also selected together). Combinations other than above, cut off the output when overcurrent will not work.
And also, Slave unit is equipped with -LC option, therefore, if Slave unit is used indivdually, out will be either CV or CC.

*3 In case you operate power supplies with CV/CC mode under Master-Slave connection, select -LC option for Master unit and all Slave units (the other options can be also selected together). Combinations other than above, CV/CC will not work.
And also, Master unit and each Slave unit equipped with -LC option, therefore, if each unit is used individually, out will be either CV or CC.
