This enables two or more power supplies to be placed in parallel for increased output current or in series for increased output voltage.
With master/slave operation, power supplies operate at near equal voltage and current.
TS series power supplies can be configured through the front panel for different applications.
The power supply can be programmed to have its control functions accessible from the front panel, rear connector, or through RS232, optional IEEE-488, or optional ethernet communications.
Sensing can be established at the output terminal of the power supply or through a rear terminal block for sensing at the load.
An external interlock can be set to enable operation only when an external connection is made.
Even calibration has been simplified with front panel access to calibration digital potentiometers.
TS series power supplies incorporate an optically isolated feedback system.
The result is that all user interface circuitry is referenced to earth ground -- not the negative terminal of the power supply.
This enables users to connect external circuitry without concern of ground loops or voltage breakdown.

TS series power supplies are designed to operate at rated load 24 hours per day.
Standard air cooled units are equipped with variable speed, load dependent blowers to maintain comfortable margins for removing heat from sensitive power semiconductors.
Variable speed operation maximizes fan life and a minimises external environmental hazards.
Optional water cooled models contain integrated semiconductor chillers and air to water heat exchangers to manage cooling of heat producing components.
This option allows the power supply to be sealed from the environment enabling placement in harsh environments.
These units provide long life in plating facilities, electrodeionisation treatment plants, shipboard, and other corrosive environments.
Water cooling also permits power supplies to be stacked in high density equipment racks where air cooling is not possible or desirable.
TS series power supplies have extensive diagnostic functions -- all of which, when activated, take command to shut down the system.
Diagnostic functions include phase loss, excessive thermal conditions, over voltage trip, over current trip, fuse clearing, and program line.
Program line monitors externally applied analogue set point signals to insure they are within the specified range.
Upon a diagnostic fault condition, main power is disconnected and the diagnostic condition is latched into memory.
Pressing the clear key clears the memory.
All diagnostic functions can be monitored through a rear connector.
Furthermore, control functions can also be set through the rear connector to allow simultaneous control of one or more TS series units.
TS series supplies have three levels of over voltage/current protection: shutdown of controlling insulated gate bipolar transistors (IGBT's), disconnect of main power, and input fuses.
After an over voltage/current trip condition, the supply must be reset.
The Remote Interface Software is shipped with all TS series power supplies.
The software provides the user with a quick method to operate a Magna-Power Electronics's power supply under computer control.
The remote interface software has six windows: the virtual control panel, command panel, register panel, calibration panel, firmware panel, and modulation panel.
The Virtual Control Panel emulates the front panel of the TS series power supply, the Command panel programmes and reads SCPI commands with user friendly buttons, the Register Panel programs and reads registers, the Calibration Panel enables calibration of the digital potentiometers, the Firmware Panel enables the program stored internal to the power supply to be upgraded, and the Modulation Panel eases programming of modulation parameters.
