PSW 250-4.5

PSW 250-4.5 is a PSW-series single-output multi-range programmable switching DC power supply. The CV/CC priority selection of the PSW-series is a very useful feature for DUT protection. The conventional power supply normally operates under CV mode when the power output is turned on. This could bring a high inrush current to the capacitive load or current-intensive load at the power output-on stage. Taking the I-V curve verification of LED as an example, it becomes a very challenging task to perform this measurement using a conventional power supply. With LED connected to a power supply under CV mode as the initial setting, when the power output is turned on and the voltage rises to the LED forward voltage, the current will suddenly peak up and exceed the preset value of current limit. Upon detecting this high current, the power supply starts the transition from CV mode to CC mode.

• Supports parallel operation up to 250V/13.5A (4.5A single unit, 9A with 2 units, 13.5A with 3 units)
• 360W power rating
• CV/CC priority; particularly suitable for the battery and LED industry
• Adjustable voltage and current slew rate
• High efficiency and high power density
• LAN, USB, analogue control interface
• LabView driver
• OVP, OCP and OHP (OTP) protection
• User adjustable bleeder control to quickly dissipate the power after shutdown to safe levels
