Compact High power
CVCC programmable DC power supply
- Voltage: 6V to 1.5kV
- Current: 1.2A to 1000A
- Power: 750W to 15kW
- PFC circuit and universal input
(For some models)
VOL series is no longer available as we have stopped the production and sales this model in January 2021. Meanwhile, we support. PVCE series is available as the successor model, and more information on the series can be found here.
PVCE seriesThe new standard model of rack mountable DC power supply
VOL series are the new standard model of rack mountable DC power supplies that are designed on attention to "Cost performance", "Wide variety" and "High reliability". Offering original low noise switching method and wide lineups of 6 V to 650 V/600 W to 15 kW total of 157 models to meet various applications.
Also, they are to achieve high reliability as a result of our high voltage power supply technology built up over 30 years. In addition, by carefully selecting the features and pursue the cost down, we could achieve power supplies which keeps same low noise, high stability, and high reliability, but more reasonable price. VOL series support strongly R&D as power supplies that are to be used for various applications and user friendly. (Some models correspond to CE.)
Features and Benefits
- Compact and high power Max 15 kW
- Ideal for research and development with low noise switching method.
- Power Factor Correction (PFC) circuit and universal input wound not select the place of operation.
- Various operations by connecting multiple power supplies, such as master/slave, is possible.
- VOL adopts large four-digit monitor display for both voltage and current, which contributes to precise monitoring with better recognition.
- Operability and safety are improved with new features of key-lock function and acceleration rotary encoder, that increment will vary by speed of rotation.

Dual Tracking, Multiple Outputs
Dual tracking control, which enables both positive and negative outputs simultaneously in master slave operation, is possible. Multi outputs and various versatile operations are also possible by combining above dual tracking control and slave local mode. Positive and negative output (+V, -V) of dual tracking control and set the output voltage of slave local mode can be output simultaneously by turning on the master unit.


Digital Interface
Digital control of USB/RS-232C/RS485/GPIB and one-control on master slave operation.

- (A) CO-M Cable
- A two-meter cable is provided in each unit. If you need a longer cable or additional cables, please consult with our sales staff.
Key Lock
Lock all front panel operation to prevent erroneous operation. (Emergency stop by power switch is valid.)

Lock all the function other than reset lock mode.
This mode is good for purpose to avoid mis-operation completely.

Operations
Operation example
VOL series of same model number can be connected in series or parallel to increase output voltage or current. In that case, local control or the control in the digital master slave is recommended.
Because the common of the outside input/output control connector (TB1) is connected to the negative output, please do not connect common more than two.
Series Operation
Total output voltage is to be up to 250 V. Therefore, for models with output voltage of over 250 V, series operation cannot be conducted. Output current is to be the smallest current of those.

Parallel operation
Please keep all the settings of voltage the same. The output current will be the summation of each current. Please keep OVP level of power supply maximum to prevent any damage.

Split Operation
+output and –output are available.
