DC Power Supply OWON SPM3051
General information
OWON SPM3051 combines a single-channel programmable DC power supply with a rated voltage of up to 30 V, current of 5 A, and a power output of 150 W and a built-in high-resolution 4½ digit auto/manual range multimeter with multiple measurement functions in a small body for convenience of use and ease of carrying.
OWON SPM3051 has multiple settings for circuit protection, a flexible configuration of voltage and current within the rated power range, and a variety of measurement and testing functions, thus allowing fora wide range of applications.
Features
- 2 in 1 device integrating a DC power supply and a digital multimeter
- Output voltage and current curve monitoring function, facilitating the repair of consumer electronics such as laptops and smartphones, PCB aging testing, battery charging and discharging testing
- Constant voltage/current output with intelligent switching mode to protect the circuit: after the actual current exceeds the preset current value, the power supply automatically switches to the CC mode
- List waveform editing output, with 10 editable groups of timing output function
- Four groups of memory shortcut parameters for quick output
- Overvoltage and overcurrent protection
- Dual DC power supply and multimeter display interface
- USB communication interface
- In-built multimeter measurement functions:
- AC/DC voltage
- AC/DC current
- capacitance
- resistance,
- continuity test
- diode (0-2 V) test
