Operational 5" touch screen with 3 definable background colors, 3 spin knobs with push-select and two push buttons give a clear and intuitive control. Patented multi-function HOME/RETURN key. Patented output ON/OFF button gives an extra layer of safety, allowing powered output only when both internal switches are triggered. Two kinds of output mode which can be changed following adjustment or after confirmation. Programmable over-voltage and over-current protection. Programmable output ramp-up and ramp-down protect the device under test. Up to 8000 sets of V/A/W data at 1ms intervals can be...

Output Characteristic 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. Output power comparison Wide range 1950V/18kW power output range Conventional 1950V/18kW power output range Power rating (DSP-WR / DSP-WE / DSP-WA / DSP-WAe) Output Power (32 models) * Any output power combination from V1 x A1 to V2 x A2 is possible, but V1 x A2 is not allowed.

Block Diagram Power Module The power module of the DSP-Wx series uses a state-of-the-art SiC MOSFET/SBD and full 3-stage structure, with the following features: : 1. 3-phase line input keeps AC mains balanced and conforms with worldwide power distribution standards. 2. Forms 10-18kW models by internal series or parallel. 3. All power modules (up to 3) inside the unit are controlled by a single CV/CC circuit, eliminating chasing during transition. 4. Full 3 stage structure delivers the best efficiency with synergy efficiencies near 96%. 5. The 1st stage (APFC) has a two-phase interleaved...

Techniques Comparison iDRC's decades of research and development allow us to offer DC power supplies that are significantly more efficient and environmentally friendly. Compared with traditional DC power supplies, our DSP-Wx series systems offer: higher efficiency iDRC CDSP series times faster DSP-Wx series MHz Switching Frequency The DSP-Wx multi-phase interleaved design boosts switching frequency to 1 MHz. The higher frequency allows the system to output with minimal ripple and respond to load variations faster than other systems. The DSP-Wx series is the first programmable DC power...
