TTi MX100TP – Triple Multi Range 315W Combined Output with USB, RS232 and LAN Interfaces

• Three high performance outputs each with full functionality
• 315 watts total power
• Range switching provides up to 70 volts and up to 6 amps
• Includes USB, RS232 and LAN  Interfaces

The MX series uses mixed mode regulation to provide up to 420W of power split across up to four outputs, this series differs from most other multi-output power supplies in offering full capabilities on all outputs.

Each output features CV or CI operation, simultaneous high resolution metering, switchable remote sensing, OVP and OCP trips, and an individual output switch. To increase its ability to match the widest range of applications, each output has more than one range giving the choice of higher voltage or higher current.

When higher power is required, up to two outputs can be disabled to provide twice the power from one or two outputs – up to 210 watts for the MX100T/MX100Q and up to 360 watts for the MX180T.

Typical Application Areas Include:

• Medium to high power bench-top applications requiring multiple outputs
• Situations where voltage and current requirements may vary widely between projects
• Powering rail sensitive circuits using the on/off synchronism and sequencing
• Repetitive testing applications requiring multi- output settings memories
• High density system applications requiring multiple outputs from limited rack space
• Remote control applications where bus interface requirements may change

When a higher power level is needed, up to two outputs can be disabled to provide 210 watts (MX100T/ MX100Q) or 360 watts (MX180T) from a single output.

High Setting Resolution

For applications requiring the highest accuracy and resolution, up to 5 digit setting and metering is provided for voltage and current. Best resolution is 1mV/0.1mA (MX100T/ MX100Q) and 1mV/1mA (MX180T).

Non-volatile stores are incorporated for rapid recall of voltage and current settings (along with Range, OVP and OCP). Each output has its own set of 50 setting stores.

Multi-Output Linked Memories

In addition to the individual memories for each output, 50 further memories are provided that store settings for all outputs together.

Clarity and Ease-of-use

Unlike some other multi-output power supplies, the MX Series displays voltage, current and other essential information for all outputs simultaneously.

The illuminated keypad includes soft keys via which voltage or current can be instantly set for any output, or which can be used to set up other functions using a menu system. Values can be set numerically direct from the keypad or can be adjusted in a quasi-analog manner using the control knob.

A unique capability of the products is synchronous on/off switching and programmable on/off sequencing. 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.

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.

Current Meter Averaging

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 stabilised by displaying the average of several readings to reduce the speed and extent of the variation.

Each output also has an individual display mode which provides larger digits and enables OVP, OCP, current meter averaging and range to be viewed and changed. Access to 50 memory stores for the output is also available from this screen.

Front Panel Locking

An illuminated front panel key locks out the keypad to guard against accidental mis-setting. For even greater security, as might be required when the PSU is incorporated into a fixed system, the keypad can optionally be locked using a pass code chosen by the user.
