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.

[caution] Total output voltage is to be up to 250V. Therefore for models with output voltage of over 250V, series operation cannot be conducted. Output current is to be the smallest current of those.

Please keep all the settings of voltage the same. Output current will be the summation of each current.[caution] Please keep OVP level of power supply maximum to prevent any damage.

[caution] In case of +- operation, the remote connector is connected to negative output terminal. So never connect other remote control to the connector.

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.

Definition of specifications

Connection · Operation

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.
