Comparison of PWR1600L and PWX1500L
Extending the capacity
Series operation
You can connect up to two units in series. The total of the output voltages of the two units is applied to the load. The voltage setting accuracy is the same as the accuracy of an individual unit.
*You cannot perform master-slave configuration in series operation. *Excluding the PWX750HF and the PWX1500H.
Practical convenient functions are equipped as standard features.
Bleeder on/off function
The capacitor is connected to the output terminal of the PWX series, and the bleeder circuit is equipped to discharge the electric charge when the OUTPUT is OFF. For example, when the battery is connected to the output terminal, even if it is in the state of OUTPUT OFF, when the bleeder circuit is set to ON, the bleeder circuit will discharge electric charges of the battery. In this case, excessive electric discharge can be prevented by setting the bleeder circuit to OFF state. It is possible to omit the diode for reverse current prevention required for the charge of such a battery.
Rise state setting when output is on
You can set for the priority operation mode (CC (constant current) priority/CV (constant voltage) ) when the output is turned ON. It prevents the overshooting when the output is turned ON.
Preset memory function
The preset memory function allows you to save up to three combination of each preset value of voltage, current, OVP, OCP, and UVL. The saved preset value can be called from the preset memory on the front panel.
Master-slave parallel operation
In master-slave parallel operation, one unit is the master unit, and all other units connected in parallel are slave units. The master and slave units must all be the same model. You can control the whole system by operating the master. You can use master-slave parallel operation to increase the output current (maximum output current: the rated output current of one unit × the number of units connected in parallel). You can connect up to four units, including the master, in parallel. The dif ference in the output voltage and output current between the master unit and the slave u n i t s i s w i t h i n approximately 5 % of the rating.
Analog Interface
The PWX series is equipped with external voltage/resistance control, which are interfaces necessary for analog external control and monitoring applications for test power supply devices. The input external signal and the output status signal can be conducted through the J1 connector on the rear panel.
Isolated Analog Interface (factory option)
The optional isolated analog interface can be installed upon request at the time of an order. You can use a signal that is isolated from the reference potential of the PWX to control the output voltage/ current, turning output on/off, and output shut down control using an external contact, and output voltage/current monitoring. This option can be selected from the voltage control type (0 V to 5 V or 0 V to 10 V) or the current control type (4 mA to 20 mA).
