Product Description:
-
Adjustable Voltage and Current Output
The DPH8920-RF offers 0-96V adjustable voltage and 0-20A adjustable current, making it ideal for a range of applications, including laboratories, factory testing, and electronic equipment maintenance. Its ability to deliver stable and precise output ensures reliability in all use cases. -
Three Convenient Control Methods
Operate this power supply with flexibility:- Panel Buttons: Adjust voltage and current directly on the front panel.
- PC Software Control: Use free PC software that supports both SIMPLE and MODBUS communication protocols for remote operation.
- Wireless Remote Control: Manage the device within a 10-meter range. A single remote can control up to 30x99 units by configuring communication channels and addresses.
-
BUCK Architecture for Efficiency
Built on BUCK architecture, the DPH8920-RF operates with high efficiency and stability, supporting an operating frequency up to 150kHz and a voltage difference as low as 0.5V. This ensures minimal energy loss and consistent performance. -
Versatile Input Compatibility
This power supply supports input voltages ranging from 20-110V DC, allowing compatibility with various power sources, such as AC-DC switching power supplies, solar panels, wind turbines, and battery-powered systems. -
Advanced Safety Features
Protect your devices with programmable voltage and current limits that prevent over-voltage and over-current damage. A temperature-controlled fan intelligently adjusts its speed and shuts off output during overheating, ensuring safe operation in demanding conditions. -
Convenient Memory Storage
Save time and improve efficiency with 10 parameter storage slots (M0-M9). Store and recall configurations for repeated tasks, simplifying setup and workflow management. -
Rapid Voltage Regulation and Stable Output
The power supply offers a fast voltage regulation response, ensuring steady performance under varying loads. Its high conversion efficiency makes it a reliable choice for professional and industrial use.
