The classical Delta EST150 with 3 outputs and ES150/ES300 bench models has options for analoge control.

The SM800 to SM3300 Series consists of power supplies with excellent efficiency, stability and flexibility. Thanks to the auto-ranging power output, one power supply can cover two ranges of traditional power supplies with an rectangular VI-curve.
The SM3300 series can use both single-phase or three-phase grid power.
The SM15K is presented in separate AC/DC High power page.

The SM800 to SM3300 series can be controlled via the front, web interface or Ethernet. This connectivity can be expanded at any time by interface cards.
On SM3300 the Master/slave interface allows parallel operation of up to 8 units.

Auto-ranging output in the SM800 to SM3300 series allows the power supply to switch between two output regions dynamically. This feature boosts the power supply's versatility, essentially performing the function of two traditional units. The L-curve V-I diagram demonstrates the auto-ranging behaviour.

High speed programming and Power sink
The SM3300 series offers optional 10-20x higher programming speed and lower output capacitance, perfect for laser applications, fast test systems, or as a low parallel capacitance current source in plasma chambers. The Power Sink Option absorbs bursts of power, maintaining constant output voltage. It's ideal for PWM-speed control in electric motors and automotive waveform generation. 

SM15K Flex output
The SM15K series delivers unmatched versatility and flexibility with its constant power output characteristic. It adapts seamlessly to varying voltage and current requirements, offering performance equivalent to three traditional power supplies with a rectangular VI-curve or autoranging output. This results in exceptional value and adaptability, ilustrated by Flex output in left column.

Bidirectional Power Flow
The SM15K series standard offers bidirectional power flow, with the ability to absorb 100% of the power, and is symmetric across both quadrants, see figure on the left column. Voltage and current are fully programmable from zero to maximum. Delta's innovative Power Regeneration Technology ensures up to 95% efficiency by returning full power to the grid, eliminating the need for expensive water-cooling systems. This leads to cost savings, reduced carbon footprint, and highly efficient, compact test setups ideal for battery, PV, and inverter applications.
