The DSP-Wx series provides various voltage and current combinations at full power. This makes the DSP-Wx useful in a broader range of applications, replacing multiple traditional DC power supplies.

DSP-Wx series provides CV(Constant Voltage), CC(Constant Current) and CP(Constant Power) modes; users can select the mode suitable to their test requirements.Below shows an application of CC mode avoiding any current/voltage overshoot during diode validation.

The DSP-Wx series includes built-in resistance simulation allowing users to replicate battery behavior, accurate to 5 digits.

The output slope is based on the Slew Rate setup. If the Ramp Up/Down is more rapid than the Slew Rate,the DSP-Wx will default to Slew Rate settings. In the example below, the Ramp Up setting is higher than the Slew Rate, so the output voltage increases more gradually.

Several configurations of pre-assembled rack with Power Distribution Unit (PDU) are available.

The DSP-Wx series automatically dissipates energy to about 60V or less within 10 seconds of Output OFF.

iDRC wide range DC Power Supply can adjust output range to fit various battery layouts. The DSP-Wx series reduces the cost of purchasing purpose-built power supplies. By using DSP-Wx series DC Power Supply, one unit can reach high voltage/low current and low voltage/high current, significantly reducing the cost and space requirements of test equipment. DSP-Wx series Wide Range DC Power Supply with sufficient current and voltage capacity to test batteries in parallel or series.

Definitions for miniature fuses and general requirements for miniature fuse-links

• DSP-WA/WAe/WAs series without front panel are suitable for ATE and SUBsidiary unit application.
• Full function design capable of acting as a MAIN unit.
• Equipped with indicators to show operating conditions for convenient visual checks.

While electric vehicle design pursues better endurance and energy conversion efficiency, there is an increasing demand for highly flexible and reliable DC power supplies.The DSP-Wx series DC power supply provides 5kW-1800kW wide-range voltage/current control. They are capable of adjusting to all test scenarios.

The DSP-WS series power supplies simulate the output of solar arrays and fuel cells, making them capable of testing a wide range of products to meet domestic and commercial regulations.
Commercial Solar array Power System voltage rating has improved from 1000V to 2000V.
Higher voltages require less current to achieve the same power rating so new generation solar cell arrays usually have high loop voltages to simplify wiring, reduce capital expenditures and lower running costs.
DSP-WS DC Power Supply 1950V output meets the demand of high voltage testing.
