Technical Reference & Guidelines
Frequently Asked Questions for 40V DC Power Supplies
Q: Can I operate a 0-40V DC power supply in both Constant Voltage (CV) and Constant Current (CC) modes?
Yes. All catalog 0-40V power supplies support automatic, seamless CV/CC crossover. You can set the target voltage up to 40V and current limit independently to protect sensitive Devices Under Test (DUT) from unexpected overcurrent.
Q: What AC input voltage options are supported for these 0-40V 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 0-40V 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.
