4 MX-Q & MX-QP Series 2 Instruction Manual
PRODUCT DESCRIPTION
The MX100Q is a quad-output laboratory power supply incorporating four outputs of
similar power and features. Each output can provide 0 to 35 volts at 0 to 3 amps (105
watts), with range switching extending its capabilities to provide voltages up to 70V and
currents up to 6A (210 watts).
The MX103Q is a quad-output laboratory power supply with three outputs that provide 0
to 35 volts at 0 to 6 amps (210 watts), and a fourth providing 0 to 35 volts at 0 to 3 amps
(105 watts)
Power sharing allows up to 420W total output power at any time across the four outputs
without disabling other outputs.
Mixed-mode regulation is used, which combines switch-mode power conversion with
linear final regulation to give good noise and transient performance.
All information is displayed on a large backlit graphic LCD, and control is via soft keys
together with a numeric keypad and spin wheel.
Advanced features include 50 settings memories for each output plus 50 further memories
that record the settings for all four outputs together.
TripLink is a feature that allows the OVP and OCP trips of one output to be linked to other
outputs. If a trip occurs, all linked outputs will be tripped simultaneously.
Multi-On and Multi-Off keys supplement the individual output On/Off keys and can be
programmed to turn the outputs on or off in a timed sequence.
The front panel can be locked to prevent accidental changes to settings.
The power supply is housed in a ¾ rack width, 3U high case with front input ventilation. An
intelligent fan is used to minimise cooling noise.
The MX100Q & MX103Q P version has the same manual control features and adds USB,
RS232, GPIB (Optional), and LXI-compliant LAN interfaces together with duplicate power
and sense terminals at the rear.

INSTALLATION
Mains Operating Voltage
This instrument has a universal input range and will operate from a nominal 115V or 230V
mains supply without adjustment. Check that the local supply meets the AC Input
requirement given in the Specification see ‘Technical Specifications’.
Mains Lead
Connect the instrument to the AC supply using the mains lead provided. Should a mains
plug be required for a different mains outlet socket, a suitably rated and approved mains
lead set should be used, which is fitted with the required wall plug and an IEC60320 C13
connector for the instrument end. To determine the minimum current rating of the lead set
for the intended AC supply, refer to the power rating information on the equipment or in
the Specification.
Mounting
This instrument is suitable both for bench use and rack mounting. It is delivered with feet
for bench mounting. The front feet include a tilt mechanism for optimal panel angle.
A rack kit for mounting in a 19” rack is available from the manufacturers, or their agents
and distributors overseas.
Ventilation
The power supply is cooled by an intelligent multi-speed fan which vents at the rear.
Cooling air is drawn in through slots in the front panel directly above the terminals and by
slots in the base of the unit close to the front.
In a rack-mounted situation, when using the recommended Aim-TTi rack mount (RM460),
no additional space is required above or to the sides of the unit. Some air space below the
unit will ensure the best possible airflow and the lowest fan speeds for a given power but is
not required.
Ensure that the ventilation slots and rear fan exhaust are not obstructed. In the event of
overheating, a temperature trip will turn all of the outputs off – see ‘Over-temperature Trip
(OTP)’.

terminals
For each output, the load should be connected to the positive (red) and negative (black)
terminals marked OUTPUT. Both are fully floating and can be connected to the ground
terminal or to a terminal of another output. The outputs of the power supply are fully
floating and may connected to other equipment resulting in the voltage appearing at a
terminal being greater than the output voltage alone.
CAUTION
The maximum permissible voltage between any terminal and earth ground ( ) is
300VDC; the maximum permissible voltage between either terminal of one output and
either terminal of another output on the same power supply is also 300VDC. Exceeding the
maximum reverse voltage (40V [80V for MX100Q OP3 & 4]) and current (3A) will damage the
unit
WARNING Such voltages are exceedingly hazardous and great care should be taken by the
user. The front terminals are intrinsically touch proof, but hazard may still exist depending
upon the type of connection made to the terminal. On no account should the connections
be touched under such use. Voltages appearing on the front terminals will also appear on
the rear terminals
Remote sense connections to the load, if required, are made from the positive (+) and
negative (-) SENSE terminals. Switch the SENSE switch to REMOTE when remote sensing is
required. Switch back to LOCAL when remote sensing is not in use. See ‘Remote Sense’ for

Initial operation
Selecting the parameter to edit
The function of the soft keys ①change as the instrument is operated, the current
function is shown on the display in a box above each key ②. A hidden box means that the
key currently has no function ③.
For example, to set the voltage, press the soft key associated with the required function
④, the selected key is illuminated.
When active, appears in front of the selected parameter ⑤. (Pressing the same key
again or pressing ESC (Escape) cancels the key and disables all setting capability.)
Setting voltage or current using the numeric keypad
Press the required numeric key, the OK key will start to flash. When the
numeric value entry is completed, press OK to be accept and action.
Entry can be abandoned at any point by pressing ESC (Escape)
Entry is in volts or amps to a resolution of 0.001 volts and 0.0001 amps
for 16V and 35V ranges, and 0.01 volts and 0.001 amps for 70V range on
the MX100Q/P. Entries need only to be completed as far as the desired
digit of resolution, e.g. to enter 5.000 volts it is only necessary to enter 5 followed by OK.
Setting voltage or current using the spin wheel
The spin wheel is disabled by default, press the Enable key to activate, the key
will be illuminated when active, the spin wheel will then change the output
settings immediately (live), no OK confirmation is required.
The spin wheel has a non-linear action. If it is moved slowly the value is
incremented in minimum steps (1mV/0.1mA for 16V and 35V ranges, or
10mV/0.1mA for 70V range on MX100Q/P). When the spin wheel is rotated more rapidly
the rate of increment is increased, enabling the value to be changed quickly. The action of
the spin wheel can be changed from System Preferences to reduce the speed-related
increment rate if preferred. see ‘Changing System Preferences’ for more details.
Turning the Output on
Alternate presses of the On/Off key turn the output on or off. The on state
is indicated by the key being illuminated in red. At power-up, the default
behaviour is for all the outputs to be set to off. However, the user can
change this default setting such that the outputs are restored to their
condition when the instrument was switched off. This change is made from
System Preferences, see ‘Changing System Preferences’for more details.

The eight soft keys are used to set voltage and current (V set and I set), over-voltage and
over-current protection levels (OVP & OCP), current meter averaging (I avg), range
selection (Range) and store or recall of settings (Stores).
Setting voltage or current is as previously described in ‘Initial operation’.
Power Display (VxA)
The power being supplied to the load (VxA) is displayed in watts on the lower right-hand
side. The value is calculated from the metered values of voltage and current and is
displayed with a maximum resolution of 0.001 watts; and 0.01 watts for outputs 3 and 4 in
70V range on the MX100Q/P model.
Selecting Current Meter Averaging
Iavg
Current meter averaging is useful when the load current is varying rapidly. It can help to
reduce the variation in the reading and make the display easier to follow.
Selection is done from each individual output screen. Pressing the soft key marked Iavg
toggles current meter averaging on or off. The present status is shown in the area above
the key and by an asterisk ( * symbol) appearing directly after the current meter. This *

Pressing the OVP/OCP soft key creates a new set of soft keys from which OVP & OCP values
can be set or turned on or off.
Pressing OVP Set causes the key to illuminate and makes the OVP value settable. A new
value can be entered using the numeric keypad or by the spin wheel if enabled. OVP can be
turned off by pressing OVP OFF and turned back on by pressing OVP On. The previous OVP
value is retained when OVP is off and is displayed in brackets.
Similar capabilities are provided for controlling OCP.
NOTE
When set to OFF, the function is not completely disabled but is set to the maximum value
for the output. Thus, if OVP was set to OFF on output 1 and an external voltage greater
than 40V was applied to the terminals, an OVP trip would occur.
More information on using OVP and OCP is provided in section ‘Using OVP and OCP’.

MENU - ADVANCED FUNCTIONS
Menu
Pressing the key marked Menu selects the System Menu screen, providing access to
advanced options and functions.
Each item of the system menu is selected by using the two arrow keys, or by turning the
spin wheel until the desired line is highlighted, and then pressing the Select soft key. This
selects a menu screen relating to the function selected.
Setting Voltage Tracking
Menu > Voltage Tracking Setup
By default, all four outputs are completely independent. However, it is possible to make the
voltage of an output always equal to the voltage set on another output. This is called
voltage tracking.
Tracking voltages can be useful in setting up adjustable voltages of equal or opposite
polarity, or when outputs are wired in parallel or in series.
Three alternative voltage tracking arrangements are possible:
Mode 1: Output 2 tracks Output 1.
Mode 2: Output 4 tracks Output 3.
Mode 3: Output 2 tracks Output 1 and Output 4 tracks Output 3.
The controlling output is described as Master, whilst a controlled output is described as
Slave. Voltage tracking can only be selected when the voltage range for the Slave output is
equal to or higher than that of the Master output.
The tracking condition is displayed on the top line of the display, see ‘Display Symbols’.
NOTE
When tracking is set, changing the range of either the Master or Slave output will cancel
tracking regardless of the direction of the change.

Current Meter Averaging Setup
Menu > Current Meter Averaging Setup
The degree of averaging of the current meter reading when Iavg is turned on can be set
individually for each output.
The System Menu function “Current Meter Averaging Setup” provides an individual
choice of Low, Medium or High for each of the four outputs set via the soft keys. The
default value is Medium.
Store and Recall of Settings for All Outputs
Menu > Stores: All Outputs (Store/Recall)
Each output has its own set of 50 memories in which settings can be stored for that output.
A further set of 50 memories is provided that allow the user to store and recall the settings
status for all four outputs simultaneously.
Unlike the individual memories, which store only Range, Volts, Amps, and OVP/OCP, these
memories also store the output ON/OFF state, current meter averaging state, and the
Multi-On/Multi-Off settings.
The System Menu function “Stores: All Outputs (Store/Recall)”creates a screen similar
to the Stores screen for the individual outputs, but with an extra column for ON/OFF. The
four outputs are listed on successive rows.
The output On/Off state is included in order to allow memories to be recalled in sequence
including the turning of outputs on or off.
NOTE
Recalling a memory will override the existing On/Off state and this should be considered
when setting up the power supply prior to storing each status entry.
Current meter averaging being set on is indicated by the * symbol after the set current
value. If any of the Multi-On/Multi-Off settings are set to Delay this indicated by a clock
symbol after the On/Off state.
NOTE
Output delay settings are only applied when the Multi-On/Multi-Off function is used and
not when a memory is recalled.
