Functions
Pulse or Ramp Sequence, Master Following
The series meets a wider range of applications through the following output control functions.
A. Pulse Sequence
According to the combination with multiple setting, the sequence operation is available by using the
voltage and current settings stored respectively in Memory a, b, and c. Also, setting the number of
operations is provided, let alone continuous operation.
As the set time of Memory a, b, c or off is
set to 0.0, the output control has a great variety of operations such as continuous operation in both of
Memory a and b or among Memory b, c, and off. Thus, the function is ideal especially for product
evaluation tests.
ta, tb, tc, and toff can be set respectively with the range of 0.0 second, 1.0 seconds to 9999 hours 59 minutes 59.9 seconds.
B. Ramp Sequence
In this function, the ramp operation is available within the voltage and current settings (or up to 0 V/0
A starting the said values).
It is excellent for increasing or decreasing the voltage and current
values gradually. The function can also effectively reduce the load damage caused by overshooting.
* The ramp operation can be set with a range among "both settings of voltage and current value", "voltage setting only", and "current setting only".
t1 and t2 can respectively be set with the range of 0.0 second, 1.0 seconds to 9999 hours 59 minutes 59.9 seconds.
C. Combination of Pulse Sequence and Ramp
Features of pulse sequence operation and ramp operation can be combined for more convenient operation. In
combination with multiple setting, the sequence operation is available by using the voltage and current
settings stored respectively in Memory a, b, and c.
Besides setting continuous operation, a specific
number of settings is provided. This function allows the voltage or current value to use repeatedly by
increasing or decreasing gradually to three different settings, which is really useful for various
purposes.
From t1 to t4, from ta to tc, and toff can be set with the range of 0.0 s, 1.0 seconds to 9999 hours 59 minutes 59.9 seconds.
D. Master Following
During the pulse sequence and ramp operations in master/slave control, the output signal will be sent to
the slave machine.
As the result, the slave machine can have different output status to the master
machine.
Dual Tracking, Multi Output
The dual tracking controlling is available by connecting the power to generate the positive and negative outputs in master/slave control. In addition, using the slave local mode, the dual tracking operation can consist of multiple outputs. The positive and negative output voltages (+V and -V) in dual output will output in synchronization with turning on the power of the master machine.
- Concerning the connection, please refer to "Operation example".
- With the output voltage exceeding 250 V, dual tracking is not available.
Dual Tracking
Multiple Output
Multiple Digital Interface *
Equipped with standard LAN, USB(TMC) and RS-485, the function is widely available in various communication systems. Additionally, you can download IVI driver compatible with SCPI command from our website, which is more convenient for the development of control program in programming languages such as LabView, Visual Basic and C#.
- Connection example
- With the following connections, you can readily set up systems like ATE (Auto Test Equipment)
Sink Current Suppression
When supplying power to loads with capacities like batteries and capacitors, the sink current suppression is used to reduce the reverse current flowing from the load to the unit in order to prevent a voltage drop on the load as the output is OFF or the set voltage is lowered.
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.
Multiple Setting
The series has a function to memorize both voltage and current values along with the usual presetting, which is
available for total of three.
So, you do not have to adjust multiple set values each time, which is effective especially for taking
experimental data many times in experiments or performing manufacturing process in product inspections.
Master/Slave Control
The collective control function is available for connecting up to 15 slave units to a master unit.
- (A) GP-M cable
- A two-meter cable is provided in each unit. If you need a longer cable, please consult with our sales staff.
Key Locking
The operation on the front panel can be locked to ensure no operational errors.
(Emergency stop operation using the POWER ON/OFF switch is possible in either mode.)
As all the switches are to be locked except LOCK release, it is highly effective in preventing erroneous stop at remote control
- Please note that each of the power supplies connected in parallel has no function for equally keeping the current output of the power supply. If you need a power supply with equal current output, please consult with our sales representatives.
- In master/slave control, the connection must be made between the same models.

Operations
Operation example
In PVCE series, the output voltage and current can be increased by connecting the same models in series or parallel operation. As to the control, the use of local control or digital master/slave control is recommended. External I/O control connector (TB1) is connected to the negative output, so do not share the common with more than two units.
Series operation
The total output voltage can be up to 250 V. With the output voltage exceeding 250 V, series operation is not available.
In that case, the output current comes to the one of the smallest power supply.
Parallel operation
Please use the same voltage setting for parallel operation. The output current comes to the sum of each current. In order to prevent damages, please ensure to have the maximum level of OVP of the power supply.
Split operation
Positive and negative outputs are available respectively. With the output voltage exceeding 250 V, split operation is not available.
