Features
Three models with 2, 3 and 4 outputs.
Ideal for use in research and development and on production lines
The PMX-Multi series is a multi-channel DC power supply with isolated outputs on each
channel. The PMX32-3DU (2ch), PMX32- 3TR (3ch), and PMX32-2QU (4ch) are all capable
of simultaneous output in all channels and come with an output tracking feature.
Also, channels 1 & 2 of each model can be easily connected in either series or parallel to
increase the output voltage/current at the press of a button. LAN (LXI Compliant), USB, and
RS232C are included as standard digital interfaces for easy system integration.
The PMX-Multi benefits from a low noise, series regulator design that makes this series the
perfect choice for experiments involving transistors, IC circuits, and op amp circuits as well
as R&D and production line applications.

Simple Series/Parallel Connection Between Channels
Series operation
CH1 and CH2 can be connected in series to increase the overall voltage output range. CH2 operates as master and CH1 as slave. The total output voltage will be the sum of CH1 and CH2.
Parallel operation
CH1 and CH2 can beconnected in parallel to increase the overall current range. CH2 operates as master and CH1 as slave. The total output current will be the sum of CH1 and CH2.
Tracking Feature
The tracking feature allows the operator to control the ratio for increase/decrease of output among multiple channels within the power rating. This feature can be used freely among all channels with two ratio options:absolute value variation and variation ratio.
Absolute value change
This mode allows for voltage/current settings in all specified channels to change at the same rate as a selected channel.
Variation Ratio
This mode allows for voltage/current settings in all specified channels to change in equal proportion to a selected voltage or current rating.*The variable range is from 0.0% to 200.0%
Example of operation of tracking feature: PMX32-2QU
When you turn the rotary knob during tracking operation, the outputs change at the same percentage as the preset output percentage (b/a).
b/a = d/c
This proportional expression is satisfied.
Delay Function
The optional setting creates a programmable delay between the OUTPUT switch being activated and the actual output being released. The setting range for DELAY TIME is from 0.1 – 99.9 seconds.
When power supplies are not activated properly, there is the slight risk of damage being caused to the overall system. For this reason ON delay control is a very important feature that is required for power source output. This feature is also necessary when turning output OFF, and is highly convenient for operating circuits.
Note: The actual rise/fall time with output off will vary depending on the output and load conditions. Note that the timing chart above ignores rise and fall time. There are cases where the actual delay time varies by a few tens of milliseconds even when the delay time is set to 0 seconds.
