The PW Series Power Supplies are multi-function, dual-tracking CV/CC power supplies of the stand-alone type featuring a built-in microprocessor, excellent reliability and a wide range of uses.  They provide multiple output performance and experimental and systems use that rivals the previous approach of using several single- output supplies.

Dual Tracking
Dual tracking is provided, enabling positive and negative voltages and currents to track from zero simultaneously when varied, providing positive and negative outputs with the same absolute value.  This tracking function can be disabled for individual setting of positive and negative values.

Simultaneous Digital Display of Voltage and Current
Output voltage and current are indicated simultaneously on 7-segment red LED displays, and a switch operation can be used to display the voltage and current of any of the outputs.

Presetting of Voltage and Current Value Pairs (3 points)
Three sets of frequently used voltage and currents (V-A pairs) can be preset, thereby enabling quick setup of the power supply output.  A variable adjustment enables continuous adjustment of each output.  The output on/off time can also be preset.

One-Dial Control
To simplify operation, all condition settings are selected at the push of a button, with a single rotary-encoder dial being used to set all values.  In addition, output voltage and current can be set to resolutions of 10mV and 10mA, respectively.  Normal/fast switching is also possible.

Output Protection
When the output is on, if a preset switch or variable switch is changed or the tracking switch is set to on, a protection circuit cuts off the supply output, to prevent output of unexpected voltages and currents (when the output protect switch is set to on).

Key Lock
A Key-lock function can be used to forcibly hold all setting values, thereby preventing the inadvertent changes of values during a power supply operation extending over long hours, or when you leave the power supply unattended during experiments.

Last-One Memory
A backup function holds setting values, so that when the power is switched on the values in effect when power was switched off are set automatically, eliminating the need to make settings once again (except for the output switch and protect switch which are not backed up.)

ON/OFF Delay Time
For a multiple-output power supply, when more than one of the outputs are switched on or off simultaneously, the experimental device or circuit being supplied may be influenced unexpectedly, running the risk of damage.  To prevent this, the delay time feature enables you to turn on a given output only after a delay time, and turns this output off this same delay time before the other outputs.

Natural Cooling
Thanks to an energy-saving design minimizing the temperature rise inside the unit and to a structure with high heat exhaust efficiency, the unit does not need a ventilation fan, thereby eliminating trouble such as noise, vibration and absorption of dirt.

Rack Size Unit
Assuming the use in experimental fields and in combination with system components, the unit has a case size which complies with the rack specifications of EIA and JIS.
