Compact Multi-Output DC Power SupplyPMX-Multi Series
Each output is isolated. Simple series/parallel connection between channels. 200W Output Capacity. Three models with 2, 3 and 4 outputs.
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
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.
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 Variation
This mode allows for voltage/current settings in all specified channels to change at the same rate as a selected channel.
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.
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.
