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.

be followed by the user to ensure safe operation and to retain the instrument in
a safe condition.
WARNING
Do not operate while condensation is present.
Do not operate outside its rated supply voltages or environmental range.
THIS INSTRUMENT MUST BE EARTHED.
Ensure that only fuses with the required rated current and of the specified type are used for
replacement.
The use of makeshift fuses and the short-circuiting of fuse holders is prohibited.
Use of this instrument in a manner not specified by these instructions may impair the safety
protection provided.
Any interruption of the mains earth connector, inside or outside, will make the instrument
dangerous. Intentional interruption is prohibited. The protective action must not be negated by
the use of an extension cord without a protective conductor.
Any adjustment, maintenance, and repair of the opened instrument under voltage must be
avoided. When connected, terminals may be live and opening the covers or removal of parts
(except those that can be accessed by hand) may expose live parts.
Voltages above 60VDC are hazardous live according to EN 61010-1, great care must be taken
when using the power supply at voltages above this level.
Capacitors inside the power supply may still be charged even if the power supply has been
disconnected from all voltage sources but will be safely discharged about 10 minutes after
switching off.
To avoid electric shock or damage to the instrument, never allow water to get inside the case. If
the instrument is clearly defective, or has been subject to mechanical damage, excessive
moisture, or chemical corrosion, the safety protection may be impaired, and it must be
withdrawn from use and returned for repair.
CAUTION

3 - Installation
7 MX-Q & MX-QP Series 2 Instruction Manual
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)’.

Power
Output
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
more information.
The Earth terminal is connected to the chassis and safety earth ground.

NOTE Image shows the protective cover in place as supplied by the manufacturer.
The Output and Sense terminals are duplicated on the rear panel terminal block
marked Output +, Output-, Sense + and Sense-.
These connections are paralleled with their front panel equivalents. Switch the
front panel LOCAL/REMOTE switch to REMOTE when remote sensing is required.
When the rear panel output terminals are used, the use of remote sense is always
recommended to ensure that output regulation is maintained within specification;
connections can be made to either the front or the rear remote sense terminals
but never to both pairs of terminals at the same time. Switch back to LOCAL when
remote sensing is not in use.
WARNING Voltages appearing on the front terminals will also appear on the rear
terminals. The rear terminals have protective walls but are not intrinsically touch
proof. A protective cover is provided and must be used if voltages above 60 volts
DC could be present; it is advised that the cover is used at all times. If any
hazardous voltages could exist, all connections to the front or rear terminals must
be made with the power switched off on all voltage sources
