PMX-Multi Series Compact Multi-Channel Output DC Power Supplies

One-touch series/parallel connection

tandem operation

By connecting CH1 and CH2 in series within the product, the two channels can be combined to expand the voltage output range. In operation, CH2 is the master and CH1 is the slave. If the two channels are connected in series, the combined output voltage of CH1 and CH2 will be output.

parallel operation

By connecting CH1 and CH2 in parallel within the product, the two channels can be combined to expand the voltage output range. In operation, CH2 is the master and CH1 is the slave. If the two channels are connected in parallel, the combined output current of CH1 and CH2 will be output.

tracking function

The so-called tracking function is a function that allows multiple channels to be changed simultaneously in response to changes in the reference channel. As long as it is within the active area, it can be changed from 0V (or 0A) to the rated voltage (or rated current). In addition, the channel to be used for tracking can be arbitrarily selected, and the channel to be used as the reference can be arbitrarily set. The tracking function includes two methods, "absolute change" and "proportional change".

Absolute value change

Function to change the output voltage value (or current value) of a specified channel by the same amount (absolute value) as the change in the output voltage value (or current value) of the reference channel.

Proportional changes

This function changes the output voltage (or current) of a specified channel by the same ratio (%) as the set output voltage (or current).

※Variable range: 0.0%～200.0%

Example of tracking function in action: PMX32-2QU

When the knob is rotated during the tracking function operation, the output is changed by the same ratio as the preset ± output ratio (b/a). b/a = d/c The proportional equation is established.

delay function

When the OUTPUT switch is pressed, the time for each input to be OUTPUT ON (ON DELAY) or OFF (OFF DELAY) can be set. The DELAY TIME can be set from 0.1s to 99.9s. If the power is not supplied in the specified order, the entire system may be out of control or even damaged, so it is necessary to set the delay control for the ON time when the power is output. It is also necessary to set the delay control when the power supply is output OFF. This function is very convenient for driving this type of circuit.

Easy access with embedded WEB server

The web server embedded in the PMX-Multi series can be accessed using a WEB browser on a personal computer, smart phone, tablet PC, etc. for power control and monitoring.

rear panel

LAN (LXI equivalent), USB, RS232C communication interfaces are standard.

ON/OFF control of the outputs is possible via an external contact.
