Triple output power supply has twelve ranges

Aim-TTi has differentiated its laboratory power supply from other triple output power supplies, by having all three outputs with a similar power capability with each providing 0 to 35V at 0 to 3A. Range switching extends the capabilities so that outputs can be set to 16V/6A or 70V/1.5A for maximum versatility.

The MX100T is a 315W watt precision laboratory power supply. Where higher power is needed from one output, internal switching circuitry enables up to 210 watts to be provided from a single output arranged as either 35V/6A or 70V/3A.

All outputs are fully isolated and independent but voltage tracking can be selected to make two or even three outputs track a single voltage control. The isolated tracking capability is useful for creating tracking voltages to different ground points, tracking voltages of opposite polarity, or series and parallel connection of outputs.

The MX100T has a large backlit graphic LCD that can show full settings for all three outputs simultaneously. Soft key control provides a fast and intuitive user interface that includes other display modes and menu screens when required.

Voltages and currents can be set by direct numeric entry or in quasi-analog mode using the large spin wheel. Each output has switchable remote sensing and variable over-voltage and over-current protection trips.

200 settings memories are provided arranged as 50 for each output and a further 50 that store the settings for all three outputs simultaneously.

Each output has its own DC On/Off control key but additional keys are provided that turn any combination of outputs on or off simultaneously. This function can be extended to turn the outputs on or off in a timed sequence.

The front panel can be locked against accidental operation by the Lock key. If further security is required locking can be done using a four digit pass code.

The MX100T is housed in a compact case suitable for benchtop or rack mounting (half rack width by 3U height). A rack mount for one or two units is available. Front input ventilation is used to enable horizontal and vertical stacking without compromising cooling.

It has all the same features but adds remote control via USB, RS232, GPIB and LXI compliant LAN interfaces. It also includes duplicate terminals on the rear panel.
