• Up to 70V/3A or 35V/6A per output
• 420W total power
• Up to 210 watts from a single output with power sharing
• Multiple range combinations for maximum flexibility
• Low output noise and ripple via linear final regulation

The MX100Q and MX103Q both share 420W total power between four independent outputs. Each output features simultaneous high resolution metering, switchable remote sense, and an individual output switch. Versions with a P suffix (MX100QP and MX103QP) incorporate programmable interfaces (RS232, USB, LAN and optional GPIB).

• The MX100Q and MX100QP have four outputs, each capable of outputting up to 210W with power shared between them.
• The MX103Q and MX103QP have three outputs capable of up to 210W and one of 105W.
• The MX100Q and MX100QP can source up to 70V at 3A or 35V at 6A from a single channel
• The MX103Q and MX103QP can source up to 35V at 6A from a single channel and don't provide the 70V range, making them SELV compliant.

Ranges are subject to power sharing, 210W max

Ranges are subject to power sharing, 210W max (105W on output 4)

To provide its impressive power density, the MX series combines high frequency switch-mode pre-regulation with linear post-regulation to offer performance that comes close to that of an all-linear design.

Excellent line and load regulation is matched by low noise and good transient response.

Variable trips for over-voltage and over-current are provided on each output. Unlike a limit setting, the trip setting turns the output off and provides a different level of protection.

For example, when repetitively testing a unit which normally takes a peak current of 4A; the current limit could be set to 5A and the OCP to 4.1A to ensure that a faulty unit will trip the supply off and not be damaged by over dissipation.

TripLink 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.

When measuring rapidly varying loads it can become difficult to get useful readings from a digital current meter.

By selecting meter averaging, the reading is stabilized by displaying the average of several readings to reduce the speed and extent of the variation.

All outputs are completely independent and isolated. However, it is possible to configure the power supply so that the voltage on an output automatically tracks the voltage on another output.

Because the outputs are isolated, tracking can be used to set equal voltage of the same polarity or opposite polarities. It can be particularly useful when outputs have been wired in parallel or series where control can be made by adjusting a single output voltage.

• Option 1
• V2 tracks V1
• Option 2
• V4 tracks V3
• Option 3
• V2 tracks V1 and V4 tracks V3

Many circuits can be damaged if one voltage rail is present without the other, or if voltage rails are not applied in the correct order. In addition to the individual output on/off buttons there are further buttons for Multi-On and Multi-Off.

By default these turn all of the outputs on or off simultaneously. They can also be set to operate any combination of outputs in a user defined sequence with delays between 10 milliseconds and 20 seconds
