Compact and high power

400W, 800W, 1200W

Ideal for research and develop-ment with low noise switching method.

Various operations by connecting multiple power supplies, such as master/slave, is possible.

PFC circuit and universal input wound not select the place of operation.

Operability and safety are improved with new features of key-lock function and acceleration rotary encoder, which accelerate the output ramp up with the speed of rotating the encoder.

Sink-current / Disable sink-current function contribute to high speed response, and also good for applications which need constant voltage.

RK series

RK series is high power DC supply that has +10% more output power keeping the same compact size. When there is possible

needs of more power in the near future, this RK series shall be the ideal choice. One class more output increase the versatility

of usage of power supply, and contribute to decreasing number of power supplies needed, and so with the feature of power

factor correction and high efficiency this is environmentally friendly power supply with less CO2.

In addition to low noise switching method, additional features such as delay trigger when multiple units operation, pulse ramp

sequence(*1), memory function, locking function to prevent malfunction make RK series ideal fit for R&D and quality inspection.

As digital control function(*2) we newly added Ethernet interface in addition to RS-232C, RS-485, USB and GPIB, which

increase the flexibility for users' automatic measurement or production facility. Individual rotary 4 digits encoder for voltage and

current enable speedy and accurate setting.

(*1) Option (*2) Adaptors or options will be needed additionally.

Compact High Powered Supply

Highest power and smallest size in its class!!Worldwide universal input.

Function to memorize 3 different voltage and current settings in addition to standard preset function.No need to adjust the output when different setting, and convenient function for production inspection process or testing which require frequent data taking.

<NOTE> It is not possible to stabilize the output by controlling back current. In case of load which has inverse voltage or over rated voltage, such as inductive load or regenerative motor, protect the power supply by adding dummy resister or diode to prevent back current.

MULTI SETTING FUNCTION

DELAY TRIGGER FUNCTION

Function to select two different lock functions for two different purpose."Full Lock" locks all the functions on front panel, and "Normal Lock" locks all the functions except for ON/OFF. "Full Lock" mode shall be good in case mis-operation have to be completely avoided, and "Normal Lock" mode shall be good in case to avoid mis-operation but secure the way for emergency stop of power supply. You can select the best mode according to your level of

"Security". (In both modes, emergency stop is possible with Power Switch.)

TWO MODE LOCK FUNCTION

RK series features function to sink current, and enable to decrease the voltage quickly when turning off the output or when control the voltage down, which increase the safety of operation. In case that continuous aging test in short interval, quick voltage fall time increase the efficiency of process. On the contrary by using sink current prevention function, it is possible to prevent voltage drop on the load by decreasing the current flow from load to power supply when turning off the power supply or when decrease the output voltage.

SINK CURRENT / SINK CURRENTPREVENTION FUNCTION

Function to output ON/OFF of total 32 units from one master unit.(when Master/Slave)* It is possible to delay the ON/OFF time, and simultaneous ON/OFF setting is possible as well. Ideal function for application which requires time delay for ON/OFF setting. Ideal function for application which require to turn on power one by one or time lag. *Master/Slave function is available on the model without -LGob, -LUs1 and -LEt option. Also Master/Slave is not available when using -LDe function.

Pulse Ramp Sequence (-LDe option)

PULSE SEQUENCEUsing the stored voltage and current setting in each memory of a, b and c and multi set function, sequence operation is possible. The setting of repetition to say nothing of a continuous driving can be set. Various different operations, such as repetition of memory a and b or b ,c and off, are possible by setting the set time of memory a, b, c, and/or off to be 0.0. Thus, it makes this model suitable for evaluation test or other applications.

RAMP SEQUENCEThis function controls the ramping up and down the voltage and current to the set value (or from set voltage and current value to 0V/0A). It is convenient to increase( decrease) the voltage and current value slowly.

*The Ramp sequence can be selected from [both set voltage and current], [only set voltage], and [only set current].

COMBINATION OFPULSE and RAMPSEQUENCE

Features of pulse sequence operation and ramp sequence operation can be combined for more convenient operation. In addition, by adding multi set function, sequence operation can be operated using stored voltage and current settings in each memory. The setting of repetition to say nothing of a continuous driving can be set. For example it is possible to slowly ramp up and down the voltage and current to the three different settings, and so, it is useful on various scenes.

Note: The operation accuracy of the timer when sequensing is ±0.5%. Be careful when you use it by the long-term running operation.

When selecting DC power supply

Products on this catalog have been manufactured with consideration of safety as DC power supply, however please follow instruction manual for operation and make sure to ground the ground terminal for your safety.

Products on this catalog have been manufactured on the precondition that they are used in ground electric potential or within the range of the above series operation. Please contact our sales staff when using the product for floating of high electric potential, etc.

Products on this catalog are manufactured with consideration for protection against load discharge. However for specific experiment or continuous discharge such as sputtering, product may need discharge resistance between power supply and load or could not be used at all. Please consult with our sales staff in advance.

We recommend that you contact our sales staff with your requirement before choosing a product so that you can get the best product and the safety as high-voltage equipment is assured.

Important Notice

"F.S × catalog value(*)" is applied for ripple, stability, regulations and temperature coefficient, and "value if F.S × ±0.5%(*)" is applied for high-voltage output linearity, monitor linearity and display linearity, both in the range of 10% to 100% of maximum rating output.

Applicable scope of specifications

· Please use a short lead wire that is sufficiently thick for the connection.

· Please use PVC electric cable (105°C) that can fully tolerate the voltage used. It is necessary to consider current capacity, length limit of output wire by sensing (0.5V/lead) and so on for wiring with load. Please refer to the following diagram to determine the thickness of cable.

Please insert a diode of which rating is bigger than output voltage and current of power supply to protect the power supply from kick back of load.

Specifications in this catalog, except otherwise specified, refer to values when maximum rating output (full scale*) after 2-hour warm up.

Use several cables or copper bar for model over 350A.

Inductive load(Transformer or motor)

Indication is in rms that includes high-frequency noise.

Preset value does not show the actual output status accurately. If you need an accurate setting, conduct actual output without load and set a voltage. Also for setting current, conduct output after shorting the output terminal and gradually raise current before setting at a desired value.
