Rackmount DC Power Supplies PVCE series

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 settings, 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.

• Download brochre for detailed connection.
• With the output voltage exceeding 250 V, dual tracking is not available.

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 the back currently. In the case of load which has inverse voltage or overrated 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 a total of three.
So, you do not have to adjust multiple set values each time, which is effective, especially for taking experimental data in experiments or performing manufacturing processes 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-meters 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

External analog remote control

External Output ON/OFF

Output can be turned ON/OFF by relay or TTL signal. Logic of OUTPUT can be made reverse..

Remote Sensing

The function ensures the prevention of stability deterioration which could be caused by the voltage drop (Vo-VL) due to resistance (R) of the output wire or contact resistance.

Remote/Local Switching

As for the output voltage control, output current control, overvoltage protection, and overcurrent protection, the remote/local mode can be individually switched by relay or TTL signal.

Output Monitor (Voltage, Current)

Output Control (Voltage, Current)

Status Output

When you connect an electrical load that gives out high energy pulse output, have the remote connector (TB1) isolated to prevent the damages toward the power supply unit or install -LGob/-LIs/-LRcp option.

Digital Control

The minimum value of each model is the same as the smallest digit display on the front panel
