300V Variable Bench DC Power Supplies (0–300V Adjustable)

Q: Can I operate a 0-300V DC power supply in both Constant Voltage (CV) and Constant Current (CC) modes?

Yes. All catalog 0-300V power supplies support automatic, seamless CV/CC crossover. You can set the target voltage up to 300V and current limit independently to protect sensitive Devices Under Test (DUT) from unexpected overcurrent.

Q: What AC input voltage options are supported for these 0-300V models?

For models up to 3000W, fixed 110V–130V AC input is supported with zero power de-rating, alongside standard 220V–240V AC. Models rated at 1500W and above are shipped with heavy-duty industrial open-wire leads to connect securely to your distribution panel or industrial plug.

Q: Do these 0-300V power supplies support remote computer automation (RS485/SCPI/Modbus)?

Select programmable models (including SP/SPV/SPL suffixes and rackmount units) feature isolated RS485 / RS232 interfaces with standard Modbus-RTU and SCPI protocol support for automated test equipment (ATE) integration.

Regulated 0–300V DC power supplies available across 1A–20A current and 300W–6kW rated power configurations. Compare technical specifications, check live stock and direct USD pricing for instant online checkout or formal Proforma Invoice (PI).
